ATHLETIC GEAR PROVIDING ENHANCED MOISTURE MANAGEMENT
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority from U.S. Patent Application 61/865,416 filed on August 13, 2013 and hereby incorporated by reference herein.
FIELD
The invention relates to athletic gear and, more particularly, to athletic garments and protective athletic equipment worn by individuals engaged in sports such as hockey, football and lacrosse. BACKGROUND
Individuals engaging in various sports, such as hockey, football, and lacrosse, typically wear protective athletic equipment (e.g., shoulder pads, elbow pads, gloves, helmets, etc.) to protect themselves against impacts with other people and/or objects (e.g., pucks, sticks, playing surfaces, boards, etc.), often over and/or under athletic garments (e.g., baselayer shirts, pants and socks worn under the protective athletic equipment, team jerseys worn over the protective athletic equipment, etc.). For example, a hockey player typically wears a baselayer shirt, baselayer pants and socks under shoulder pads, elbow pads, protective pants, and leg pads, a team jersey over the shoulder pads and elbow pads, as well as protective gloves and a helmet, and possibly other gear (e.g., a jockstrap, a jock short, etc.). The player's protective athletic equipment increases sweating and humidity and reduces air circulation about the player's body. The player's "micro-climate" therefore tends to be relatively highly humid with limited ventilation. While the
player's baselayer shirt and pants may be made of moisture-wicking fabric that moves sweat towards their outer surfaces, the protective athletic equipment considerably impedes air circulation at the baselayer shirt and pants' outer surfaces and, therefore, tends to keep moisture within the player's micro-climate.
Similar issues often arise in other sports, such as football and lacrosse, in which players wear protective athletic equipment.
For these and other reasons, there is a need for improvements in athletic gear worn by individuals engaged in sports involving protective athletic equipment.

DETAILED DESCRIPTION OF EMBODIMENTS
Figures 1 to 7 show an example of athletic gear 1 1 wearable by a wearer when engaging in a sport (e.g., hockey, lacrosse, football, etc.) in accordance with an embodiment of the invention. The athletic gear 1 1 comprises protective athletic equipment 12 and an athletic garment 10 that is configured to be worn by the wearer under or over the protective athletic equipment 12. In this embodiment, the athletic garment 10 is an undergarment configured to be worn by the wearer under the protective athletic equipment 12. More particularly, in this embodiment, the undergarment 10 is a baselayer garment configured to be worn in contact with the wearer's body. In this example, the baselayer garment 10 is a baselayer shirt. The protective athletic equipment 12 is wearable by the wearer to provide impact protection, i.e., to protect the wearer's body against impacts with another person and/or an object (e.g., a puck, a ball, a stick, a playing surface, a board, a post, or any other object involved in the sport) as the wearer engages in the sport. In this example, the protective athletic equipment 12 includes a plurality of articles of protective athletic equipment (i.e., protective athletic devices), namely shoulder pads 13 for protecting a chest, an upper back, and shoulders of the wearer and elbow pads 15i, 152 for protecting elbows and adjacent parts of the wearer's arms. Specifically, in this embodiment, the wearer is a hockey player playing hockey such that the shoulder pads 13 are hockey shoulder pads, the elbow pads 15i, 152 are hockey elbow pads, and the baselayer shirt 10 is a hockey baselayer shirt.
As further discussed below, in this embodiment, the athletic gear 1 1 provides enhanced moisture management to deal with sweat produced by the player's body. Notably, in this embodiment, the athletic gear 1 1 has a quick-drying capability to increase a rate of evaporation of moisture within a "micro-climate" of the player. This is particularly useful in view of the protective athletic equipment 12 worn by the player that increases sweating and humidity and reduces air circulation about the player's upper body. In other words, the quick-drying capability of the athletic gear 1 1 helps to deal with the player's micro-climate that is affected by the protective athletic equipment 12.
1 . Athletic garment
The shirt 10 comprises an inner surface 17 for facing towards the player and an outer surface 19 for facing away from the player. In this embodiment in which the shirt 10 is a baselayer shirt to be worn under the protective athletic equipment 12, the inner surface 17 is configured to contact the player's body and the outer surface 19 is configured to contact the protective athletic equipment 12. The shirt 10 comprises a torso portion 14 including a front 16, a back 18, a top opening 20 for passing a neck and head of the player, and a lower opening 22 for fitting around a lower torso region (e.g., a waist and hips) of the player. In this embodiment, the shirt 10 also comprises a pair of sleeves 24i, 242 for receiving arms of the player. In this example, the sleeves 24i, 242 are long sleeves extending to wrists of the player. The sleeves 24i , 242 may be short sleeves (e.g., the shirt 10 may be a T-shirt) in other examples. In other embodiments, the shirt 10 may be sleeveless.
The shirt 10 comprises a material 30 making up at least part of the shirt 10. That is, the shirt 10 is at least partly (i.e., partly or entirely) made of the material 30. In this embodiment, the shirt 10 is at least mainly (i.e., mainly or entirely) made of
the material 30. More particularly, in this embodiment, the material 30 makes up at least part of the torso portion 14 and each of the sleeves 24i, 242.
In this embodiment, with additional reference to Figure 8, the material 30 is a fabric. The fabric 30 is a thin pliable textile material comprising a fibrous base substance 29 including fibers 31 1-31 F arranged in a network by weaving, knitting, interlacing, felting or otherwise crossing them. The fibers 31 1-31 F may include any suitable natural or synthetic fibers (e.g., polyester, nylon, spandex (elastane), or other fibers, or blends of these fibers). In this embodiment, the fabric 30 includes yarns 32I-32Y that comprise respective ones of the fibers 31 1-31 F. More particularly, in this embodiment, the fabric 30 is a woven or knit fabric.
In this example of implementation, the shirt 10 is a compression shirt, i.e., a form- fitting shirt that has a compression fit when worn by the player. This may help to keep muscles warm to reduce muscle strain and fatigue, wick sweat away from the player's body, and prevent or reduce chafing and rashes. To that end, the fibers 31 1-31 F of the fabric 30 may include spandex (elastane) fibers or other stretchable fibers having suitable elasticity. The shirt 10 may not be a compression shirt in other examples of implementation.
For example, in this embodiment, the fibers 31 1-31 F of the fabric 30 include polyester and spandex fibers. For instance, the fabric 30 may comprise at least 75% polyester fibers and at least 10% spandex fibers (e.g., the fabric 30 may comprise 87% 75D/72F or 75D/48F textured polyester and 13% 40 denier spandex, may be a single jersey construction weighing 155 g/m2, and may have wicking finish applied to it). The fabric 30 may have any other suitable composition in other embodiments.
The fabric 30 is configured taking into account an interface between the shirt 10 and the protective athletic equipment 12 worn by the player. Notably, the fabric 30 has mechanical properties to resist tearing or other excessive damage due to
friction or other contact between the shirt 10 and the protective athletic equipment 12. For example, in some embodiments, the fabric 30 may have an abrasion resistance of at least 10000 rubs according to ASTM 4966 - Option 1 . As another example, in some embodiments, the fabric 30 may have a bursting strength of at least 40 psi if the fabric 30 weighs 3.4 oz./yd.2 or less, or at least 55 psi if the fabric 30 weighs 3.5 oz./yd.2 or more, according to ASTM D3788. As another example, in some embodiments, the fabric 30 may have a snagging resistance of at least 3 according to ASTM D3939 (Mace Snap). These properties of the fabric 30 may have any other suitable values in other embodiments.
In this embodiment, the fabric 30 is a quick-drying material, i.e., a material exhibiting a drying rate which is relatively high, to quickly evaporate moisture as the player sweats. For example, in some embodiments, the drying rate of the fabric 30 may be at least 2.1 ml/hr, in some cases at least 2.3 ml/hr, in some cases at least 2.5 ml/hr, and in some cases even more, according to AATCC Test Method 201 of the American Association of Textile Chemists and Colorists (AATCC). Alternatively or additionally, in some embodiments, the drying rate of the fabric 30 may be at least 15 ml/hr, in some cases at least 20 ml/hr, in some cases at least 25 ml/hr, and in some cases even more, according to AATCC Test Method 200 of the AATCC. The drying rate of the fabric 30 may have any other suitable value in other embodiments.
More particularly, in this embodiment, to facilitate moisture evaporation, the fabric 30 is configured to (1 ) spread moisture over a large surface area and (2) harness heat generated by the player's body to vaporize liquid moisture.
For example, in some embodiments, a surface area of the fabric 30 may be at least 300 cm2 per square centimeter of fabric, in some cases at least 400 cm2 per square centimeter of fabric, in some cases at least 500 cm2 per square centimeter of fabric, in some cases at least 600 cm2 per square centimeter of
fabric, and in some cases even more. Alternatively or additionally, in some embodiments, a surface area of a constituent of the fabric 30 may be at least 200 m2 per gram of the constituent, in some cases at least 400 m2 per gram of the constituent, in some cases at least 600 m2 per gram of the constituent, in some cases at least 800 m2 per gram of the constituent, in some cases at least 1000 m2 per gram of the constituent and in some cases even more. The surface area of the constituent of the fabric 30 may have any other suitable value in other embodiments. To harness heat generated by the player's body to vaporize moisture, a constituent of the fabric 30 captures this heat to raise its temperature and cause vaporization of liquid moisture in contact with it. For example, in some embodiments, a specific heat capacity of a constituent of the fabric 30 (i.e., an amount of heat required to increase the temperature of a unit mass of the constituent of the fabric 30 by one degree) may be relatively low. For instance, in some embodiments, the specific heat capacity of the constituent of the fabric 30 may be less than polyester's specific heat capacity and less than spandex's specific heat capacity. The specific heat capacity of the constituent of the fabric 30 may have any other suitable value in other embodiments. Additionally or alternatively, in some embodiments, a molar absorptivity at an infrared wavelength of a constituent of the fabric 30 (i.e., a measurement of how strongly a chemical species of the constituent of the fabric 30 absorbs electromagnetic radiation at the infrared wavelength) may be relatively high. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the constituent of the fabric 30 may be greater than polyester's molar absorptivity at that infrared wavelength and greater than spandex's molar absorptivity at that infrared wavelength. The molar absorptivity at the infrared wavelength of the constituent of the fabric 30 may have any other suitable value in other embodiments.
Also, in some embodiments, a constituent of the fabric 30 may be configured to manifest an exothermic reaction releasing heat to accelerate the drying process. That is, a constituent of the fabric 30 may be configured to exothermically react (i.e., produce heat when reacting) with liquid moisture. The exothermic reaction may be chemical and/or physical. For example, in some embodiments, the exothermic reaction manifested by the constituent of the fabric 30 may be adsorption of liquid moisture by the constituent of the fabric 30, such that heat is released when the liquid moisture is adsorbed by the constituent of the fabric 30. With additional reference to Figure 9, in this embodiment, the fabric 30 comprises active elements 40I-40P to manage moisture as the player sweats, including to enhance evaporation of liquid moisture in the fabric 30.. The active elements 40i- 40P are "active" in that they have a property allowing them to induce a chemical and/or physical reaction in response to a stimulus at their surface. In this example, this reaction induced by the active elements 40I-40P helps accelerate the drying process of the fabric 30. The fabric 30 thus dries faster than if the active elements 40I-40P were omitted but the fabric 30 was otherwise identical (i.e., dries faster than a comparative fabric identical to the fabric 30 but without the active elements 40I-40P) .
In this example of implementation, the active elements 40I-40P are connected to the fibers 33ι-33κ of the fibrous base substance 29. In other examples of implementation, the fibers 33ι-33κ of the fabric 30 may themselves be the active elements 40I-40P that enhance the drying process of the fabric 30 on their own, without having distinct active elements connected to the fibers 33ι-33κ.
More particularly, in this embodiment, the active elements 40I-40P are active particles distributed within the fabric 30. In this example, the active particles 40i- 40P have an adsorptive property that causes them to adsorb liquid moisture as the player sweats. This reaction, i.e., adsorption, caused by the active particles 40I-40P helps evaporating the liquid moisture.
With additional reference to Figure 1 0, in this embodiment, each of the active particles 40I-40P is a microporous particle that includes a multitude of pores 42i- 42T (e.g., several thousands of pores) which can trap the liquid moisture.
Because of their pores 42ι-42τ, the active particles 40I-40P have a surface area which is very large, thereby vastly spreading the liquid moisture to aid evaporating it. For example, in some embodiments, the surface area of the active particles 40I-40P may be such that the surface area of the fabric 30 is at least 300 cm2 per square centimeter of fabric, in some cases at least 400 cm2 per square centimeter of fabric, in some cases at least 500 cm2 per square centimeter of fabric, in some cases at least 600 cm2 per square centimeter of fabric, and in some cases even more. Alternatively or additionally, in some embodiments, the surface area of the active particles 40I-40P may be at least 200 m2 per gram of active particle, in some cases at least 400 m2 per gram of active particle, in some cases at least 600 m2 per gram of active particle, in some cases at least 800 m2 per gram of active particle, in some cases at least 1 000 m2 per gram of active particle and in some cases even more. The surface area of the active particles 40I-40P may have any other suitable value in other embodiments.
Also, in this embodiment, the active particles 40I-40P use heat generated by the player's body to vaporize moisture. For example, in some embodiments, a specific heat capacity of the active particles 40I-40P may be relatively low. For instance, in some embodiments, the specific heat capacity of the active particles 40I-40P may be less than a specific heat capacity of the fibrous base substance 29 of the fabric 30. Thus, in this example, the specific heat capacity of the active particles 40I-40P may be less than polyester's specific heat capacity and less than spandex's specific heat capacity. The specific heat capacity of the active particles 40I-40P may have any other suitable value in other embodiments. Additionally or alternatively, in some embodiments, a molar absorptivity at an
infrared wavelength of the active particles 40I-40P may be relatively high. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the active particles 40I-40P may be greater than a molar absorptivity at that infrared wavelength of the fibrous base substance 29 of the fabric 30. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the active particles 40I-40P may be greater than polyester's molar absorptivity at that infrared wavelength and greater than spandex's molar absorptivity at that infrared wavelength. The molar absorptivity at the infrared wavelength of the active particles 40I-40P may have any other suitable value in other embodiments.
Furthermore, the adsorption of liquid moisture by the active particles 40I-40P is an exothermic reaction releasing heat that helps to accelerate the drying process. The active particles 40I-40P may be implemented in any suitable way. In this embodiment, the active particles 40I-40P comprise activated carbon. The activated carbon may be produced in various known ways. For instance, the activated carbon may be produced from carbonaceous materials such as wood, nutshells, coconut husk, coir, peat, lignite, coal, or other carbonaceous substances using known processes (e.g., physical reactivation using hot gases which involves carbonization and/or oxidation, or chemical activation using chemicals on raw material prior to carbonization), or synthetically using known processes (e.g., pyrolysis of polystyrene beads). In other embodiments, the active particles 40I-40P may comprise activated alumina (aluminum oxide), silica gel, soda ash, aluminum trihydrate, baking soda, cinoxate (p-methoxy-2- ethoxyethyl ester cinnamic acid), zinc oxide, zeolites, titanium dioxide, or any other suitable material.
The active particles 40I-40P may be incorporated into the fabric 30 using any suitable process. For example, in some embodiments, the active particles 40i- 40P may be joined to the fibrous base substance 29 of the fabric 30 using: an air
dispersion process in which the active particles are entrained in a gaseous carrier onto the fibrous base substance 29 of the fabric 30 where they are fixed; a padding process in which the fibrous base substance 29 of the fabric 30 is passed through a bath of the active particles; a liquid suspension or mixture of a binder and the active particles applied to the fibrous base substance 29 of the fabric 30; or a xerographic process using electrostatic or magnetic attraction to transfer a toner formulation including the active particles towards the fibrous base substance 29 of the fabric 30. In some cases, a protective substance may be provided onto the active particles 40I-40P to protect these active particles during manufacturing of the fabric 30 and subsequently removed. Examples of such processes are described in U.S. Patent 6,998,155, U.S. Patent Application Publication 2008/0121 141 and U.S. Patent 7,247,374, which are incorporated by reference herein. Examples of materials that can be used for the fabric 30 including the active particles 40I-40P may be commercially obtained from Cocona Inc., Boulder, Colorado.
In addition to its quick-drying fabric 30 which enhances moisture management, in this embodiment, the shirt 10 has functional features to interact with the protective athletic equipment 12, protect the player, and/or otherwise enhance the player's comfort and performance.
For instance, in this embodiment, the shirt 10 comprises grippers 44i-443 for engaging and gripping the protective athletic equipment 12 to help hold it in place. In this example, the grippers 44i, 442 are located on the sleeves 24i, 242 to engage the elbow pads 15i , 1 52, while the gripper 443 is located on the torso portion 14 to engage the shoulder pads 13. The grippers 44i-443 can grip the protective athletic equipment 12 in any suitable way to help hold it in place. In this embodiment, each of the grippers 44i-443 is a
frictional gripper that helps to hold the protective athletic equipment 12 in place by friction. That is, a frictional force exerted by a gripper 44x on an underside of the protective athletic equipment 12 is greater than a frictional force exerted by the fabric 30 on the underside of the protective athletic equipment 12 (i.e., a coefficient of friction between the gripper 44x and the underside of the protective athletic equipment 12 is greater than a coefficient of friction between the fabric 30 and the underside of the protective athletic equipment 12).
The grippers 44i-443 may comprise any suitable material to exert sufficient friction. For example, in this embodiment, each of the grippers 44i-443 comprises a tackifying material 43 such as a thermoplastic elastomer (e.g., Santoprene™), polyurethane (thermoplastic or thermoset), polyvinyl chloride (e.g., Plastisol), silicone, or any other suitable material providing tackiness. More particularly, in this example, each of the grippers 44i-443 includes frictional gripping members 45I-45B which are made of the tackyfing material 43.
Any other suitable material providing a high coefficient of friction may be used in other embodiments. For instance, in some embodiments, each of the grippers 44-I-443 may comprise hooks or loops of a hook-and-loop fastener (e.g., VelcroTM)) to engage the underside of the protective athletic equipment 12. In some cases, the underside of the protective athletic equipment 12 may include complementary loops or hooks of the hook-and-loop fastener to engage the hooks or loops of the grippers 44i-443. In other cases, the underside of the protective athletic equipment 12 may not include complementary loops or hooks, in which case the grippers 44i-443 may have hooks that anchor themselves in a material (e.g., fabric) on the underside of the protective athletic equipment 12.
The grippers 44i-443 may be provided in the shirt 10 in any suitable way. For instance, in this embodiment, the grippers 44i-443 may be printed (e.g., screen- printed) onto the fabric 30. In other embodiments, the grippers 44i-443 may be
adhesively bonded to the fabric 30, stitched to the fabric 30, or provided using any other suitable process.
In this embodiment, the shirt 10 comprises a protector 48 for protecting a body part of the player. In this example, the protector 48 comprises a neck guard at a collar 39 of the shirt 10 to protect the player's neck against cuts from and possibly other impacts with skates, hockey sticks, pucks, or other objects.
More particularly, in this embodiment, with additional reference to Figure 1 1 , the neck guard 48 comprises a cut-resistant material 50 to provide resistance against cuts from a skate's blade. In this example, the cut-resistant material 50 is a cut- resistant fabric. More specifically, in this example, the cut-resistant fabric 50 is a para-aramid fabric (e.g., Kevlar™). The cut-resistant material 50 may be implemented in any other suitable way in other examples (e.g., using high performance polyethylene (HPPE), fiberglass, etc.).
Also, in this embodiment, the neck guard 48 comprises padding 51 to provide padded protection and comfort to the player. The pad 51 may comprise foam, such as ethylene vinyl acetate (EVA) foam, expanded polypropylene (EPP) foam, expanded polyethylene (EPE) foam (e.g., low-density polyethylene (LDPE) foam), vinyl nitrile (VN) foam, polyurethane foam, or any other suitable foam, and/or may comprise any other shock-absorbing material (e.g., a gel).
Furthermore, in this embodiment, the neck guard 48 comprises an outer covering 52 disposed over the cut-resistant material 50 and the padding 51 and forming an external surface of the neck guard 48. In this example, the outer covering 52 is a fabric. More particularly, in this example, the fabric 52 is a quick-drying fabric as described above in respect of the fabric 30. The neck guard 48 is configured to receive the player's neck when the player puts on the shirt 10 and to be removed from the player's neck when the player
takes off the shirt 10. In this embodiment, the neck guard 48 is openable to receive and be removed from the player's neck. More particularly, in this example, the neck guard 48 includes a closure 53 that is selectively openable and closable to allow the player's neck to be received by and removed from the neck guard 48. In this case, the closure 53 includes a fastener (e.g., a hook-and- loop fastener, a button, etc.) to keep it closed, and cooperates with a zipper 27 extending in the back of the shirt 10. In other examples, the neck guard 48 may be stretchable to permit it to be stretched over the player's head and then closed by contracting around the player's neck when the player puts on the shirt 10.
Although it comprises a neck guard in this embodiment, the protector 48 may be provided to protect another body part of the player in other embodiments (e.g., a pad secured to the fabric 30 to protect a chest, back, shoulder, elbow, or other body part of the player).
While the shirt 10 is constructed in a particular way in this embodiment, the shirt 10 may be constructed in various other ways in other embodiments.
For example, in some embodiments, as shown in Figures 12 and 13, the drying rate of the shirt 10 may differ over a plurality of areas 60I-60D of the shirt 10. That is, the drying rate of a given one of the areas 60I-60D of the shirt 10 may be different from (i.e., greater or lesser than) the drying rate of another one of the areas 60I-60D of the shirt 10. For instance, the drying rate of a first one of the areas 60I-60D of the shirt 10 that is disposed to (i) be covered by the protective athletic equipment 12 and/or (ii) overlie a first region of the player's body which is expected to generate more sweat may be greater than the drying rate of a second one of the areas 60I-60D of the shirt 10 that is disposed to (i) not be covered by the protective athletic equipment 12 and/or (ii) overlie a second region of the player's body which is expected to generate less sweat.
For instance, in this embodiment, the area 6O1 of the shirt 1 0 is an area of the torso portion 14 of the shirt 1 0 that is disposed to overlie a front region of the player's torso and be covered the shoulder pads 13, the area 6Ο2 of the shirt 10 is an area of the torso portion 14 of the shirt 1 0 that is disposed to overlie a back region of the player's torso and be covered the shoulder pads 1 3, the areas 6Ο3, 604 of the shirt 1 0 are areas of the torso portion 14 of the shirt 1 0 that are disposed to overlie lateral regions of the player's torso and not be covered by the shoulder pads 1 3, the areas 60s, 60e of the shirt 1 0 are areas of the sleeves 24i , 242 of the shirt 1 0 that are disposed to overlie elbow regions of the player's arms and be covered by the elbow pads 1 5i , 1 52, and the areas 6Ο7, 60s of the shirt 1 0 are areas of the sleeves 24i , 242 of the shirt 1 0 that are disposed to overlie upper arm regions of the player's arms and not be covered by the elbow pads 15i , 1 52.
As an example, the drying rate of the areas 6Ο1 , 6Ο2, 6Ο3, 604 of the shirt 1 0, which overly regions of the player's torso that may generate more sweat, may be greater than the drying rate of the areas 60s, 60e, 6Ο7, 60s of the shirt 1 0, which overly regions of the player's arms that may generate less sweat. As another example, the drying rate of the areas 6Ο1 , 6Ο2 of the shirt 1 0, which overly regions of the player's torso that are beneath the shoulder pads 1 3, may be greater than the drying rate of the areas 6Ο3, 604 of the shirt 1 0, which overly regions of the player's torso that are not beneath the shoulder pads 1 3. As yet another example, the drying rate of the area 6Ο2 of the shirt 1 0, which overlies the back region of the player's torso that may generate more sweat, may be greater than the drying rate of the area 6Ο1 of the shirt 10, which overlies the front region of the player's torso that may generate less sweat, even though both of the areas 6Ο1 , 6Ο2 of the shirt 10 are covered by the shoulder pads 1 3. As yet another example, the drying rate of the areas 60s, 60e of the shirt 1 0, which overly regions of the player's arms that are covered by the elbow pads 1 5i , 1 52, may be greater than the drying rate of the areas 6Ο7, 60s of the shirt 1 0, which overly regions of the player's arms that are not covered by the elbow pads 1 5i , 1 52.
For example, in some embodiments, a ratio of (i) the drying rate of a given area 60i of the shirt 1 0 over (ii) the drying rate of another area 60j the shirt 1 0 may be at least 1 .1 , in some cases at least 1 .2, in some cases at least 1 .3, in some cases at least 1 .4, in some cases at least 1 .5, and in some cases even more (e.g., 2 or more). The difference between the drying rate of the area 60i of the shirt 1 0 and the drying rate of the area 60j of the shirt 1 0 may take on any other suitable value in other embodiments. The variation of the drying rate over the areas 60I -60D of the shirt 1 0 can be implemented in any suitable manner. In this embodiment, this may be achieved by varying a concentration or loading of the active particles 40I -40P of the fabric 30 over the areas 60I -60D of the shirt 1 0. The concentration or loading of the active particles 40I -40P of the fabric 30 in a given area 60i of the shirt 1 0 may be greater than the concentration or loading of the active particles 40I -40P of the fabric 30 in another area 60j of the shirt 1 0 such that the drying rate of the area 60i of the shirt is greater than the drying rate of the area 60j of the shirt 1 0. The concentration or loading of the active particles 40I -40P of the fabric 30 in a particular area 60x of the shirt 1 0 can be measured as a weight percent of the active particles 40I -40P in the area 60x of the shirt 1 0, i.e., a weight of the active particles 40I -40P in the area 60x of the shirt 1 0 divided by a total weight of the area 60x of the shirt 1 0 and multiplied by one hundred. For example, in some embodiments, a ratio of (i) the concentration or loading of the active particles 40I -40P of the fabric 30 in the given area 60i of the shirt 1 0 over (ii) the concentration or loading of the active particles 40I -40P of the fabric 30 in the other area 60j of the shirt 1 0 may be at least 1 .1 , in some cases at least 1 .2, in some cases at least 1 .5, in some cases at least 2, in some cases at least 4, and in some cases even more (e.g., 8 or more). In some examples of implementation, an area 60x of the shirt 1 0 may be free of active particles, i.e., there is no active particle in the area 60x of the shirt 1 0, such that the concentration or loading of the active particles 40I -40P of the fabric 30 in the area 60x of the shirt 1 0 is
substantially zero. The variation of the drying rate over the areas 60I-60D of the shirt 10 can be implemented in other ways in other embodiments (e.g., by varying a yarn size or fabric weight in different areas). To further enhance moisture management, in some embodiments, with additional reference to Figures 14 to 16, in addition to its fabric 30 which is a quick-drying material, the shirt 10 may comprise a cooling material 65 providing a cooling effect perceivable by the player. As the quick-drying material 30 works to accelerate moisture evaporation to help dry the shirt 10, the cooling material 65 may help the player feel cooler.
In this embodiment, the cooling material 65 is a fabric. The cooling fabric 65 comprises a fibrous base substance 37 including fibers 33I-33R, which may include any suitable natural or synthetic fibers (e.g., polyester, nylon, spandex (elastane), or other fibers, or blends of these fibers). In this example, the cooling fabric 65 is a woven or knit fabric.
The cooling effect provided by the cooling fabric 65 may be implemented in any suitable way. In this embodiment, the cooling fabric 65 comprises active elements 70i-70v to generate the cooling effect. More particularly, in this embodiment, the active elements 70i-70v are connected to the fibrous base substance 37. For example, in some embodiments, the cooling fabric 65 may be configured to cool down when absorbing moisture as the player sweats, i.e., a moisture-activated cooling fabric. For instance, the active elements 70i-70v may be swellable elements configured to swell when absorbing moisture to create the cooling effect. Examples of materials that can be used for the cooling fabric 65 that is moisture-activated are fabrics including Nexar™ polymers which may be commercially obtained from Kraton Performance Polymers Inc., Houston, Texas. As another example, in some embodiments, the cooling fabric 65 may be configured to cool down when absorbing heat from the player's body, i.e., a heat- activated cooling fabric. For instance, the active elements 70i-70v may be phase-
change material (PCM) elements (e.g., microencapsulated PCM elements) configured to change phase when absorbing heat to create the cooling effect. Examples of materials that can be used for the cooling fabric 65 that is heat- activated are fabrics including Thermocules™ PCM elements which may be commercially obtained from Outlast Technologies LLC, Boulder, Colorado. In other embodiments, the fibers 33I-33R of the cooling fabric 65 may themselves be the active elements 70i-70v that generate the cooling effect on their own, without having distinct active elements connected to the the fibers 33I-33R of the fibrous base substance 37. For instance, the fibers 33I-33R of the cooling fabric 65 may be configured to cool down when absorbing and trapping moisture inside them as the player sweats. Examples of materials that can be used for this purpose may be commercially obtained from CoolCore, Portsmouth, New Hampshire. Other examples of materials that can be used for the cooling fabric 65 may include IceFil by Ventex, Luxicool, Cool Jade, Advansa's Thermo Cool, and HeiQ's Adaptive.
The quick-drying fabric 30 and the cooling fabric 65 may be arranged in any suitable manner in the shirt 10. For example, in this embodiment, a quantity of the quick-drying fabric 30 in the shirt 10 is greater than a quantity of the cooling fabric 65 in the shirt 10. More particularly, in this embodiment, the quick-drying fabric 30 is present in a bulk of the shirt 10, while the cooling fabric 65 is present only in a limited area of the shirt 10 where the cooling effect may be better perceived by the player. Thus, in this embodiment, the cooling fabric 65 is present in a quick-cooling spot of the player's body, i.e., a spot of the player's body that is more efficient at cooling. The quick-cooling spot includes a pulse point, i.e., an area where the player's pulse can be felt since blood vessels are closer to his/her skin's surface, meaning that blood and body temperature can be more easily cooled. In this example, the cooling fabric 65 is disposed in the collar 39 of the shirt 10 since the cooling effect at the player's neck may be well perceived by the player. In cases where the shirt 1 0 includes the neck guard 48 as discussed previously, the outer covering 52 of the neck guard 48 may
comprise the cooling fabric 65. In other examples, the cooling fabric 65 may be disposed in other quick-cooling spots of the player's body (e.g., a crook of the elbow, a wrist, a forehead, an inner thigh, a bend of the knee, or an ankle). In some embodiments, the fabric 30, which makes up at least part of the torso portion 14 and the sleeves 24i , 242 of the shirt 10, may be a quick-drying and cooling fabric. That is, the fabric 30 may be configured such that (1 ) its drying rate is relatively high and (2) it provides a cooling effect perceivable by the player. For example, in some embodiments, as shown in Figures 17 and 18, the fabric 30 may comprise (1 ) the active elements 40I-40P for quick-drying and (2) the active elements 70i-70v for the cooling effect connected to the fibrous base substance 29. This may be done by applying the active elements 40I-40P and the active elements 70i-70v to the fibrous base substance 29 in a common process or sequential processes using known techniques (e.g., from companies mentioned above) to provide these elements in fabrics.
In some embodiments, as shown in Figures 49 and 50, the shirt 10 may comprise vents 66I-66A for ventilation. Facilitating air circulation may further enhance the quick-drying capability of the shirt 10. Each of the vents 66I-66A allows a greater air flow than parts of the shirt 10 outside of the vents 66I-66A.
More particularly, in this embodiment, each of the vents 66I-66A comprises a mesh material 63 (i.e., a material having an open texture) for ventilation. In this example, the vents 66I-66A are respectively located in underarm, back, neck, lateral sides, and arm areas of the shirt 10. The vents 66I-66A may be disposed in any other suitable manner in other examples. The vents 66I-66A may be implemented in various other ways in other embodiments (e.g., openings).
In some embodiments, the shirt 10 may comprise an indicator 71 to indicate a current quick-drying effectiveness of the quick-drying fabric 30. This "quick-drying effectiveness indicator" 71 may be useful in cases where the effectiveness of the
fabric 30 at quickly-drying itself can decrease (e.g., after the shirt 10 has been repeatedly used or has been washed with a detergent) in order to allow the player to know when the shirt 10 may no longer work as desired. While in embodiments considered above it is a fabric making up a bulk of the shirt 10, the quick-drying material 30 may be another type of material making up one or more smaller parts of the shirt 10 in other embodiments. For example, in some embodiments, as shown in Figures 19 to 21 , the quick-drying material 30 may be foam making up parts 69I-69G of the shirt 10 (e.g., pads secured to a fabric 21 making up a bulk of the shirt 10). For instance, the quick-drying foam 30 may comprise a cellular (i.e., foamed) base substance 67 (e.g., EVA, EPP, EPE, VN, PU or any other suitable cellular substance) and active elements 68I-68G, such as the active particles 40I-40P discussed above, connected to the cellular base substance 67 to enhance evaporation of liquid moisture in the foam 30. As another example, in some embodiments, the quick-drying material 30 may be a membrane.
In some embodiments, the quick-drying material 30 may be anti-microbial. For instance, in some embodiments in which it is a fabric, the quick-drying material 30 may be treated (e.g., via a pad bath or exhaust process) or may have yarn- based anti-microbial or anti-odor technology.
Although in this embodiment the baselayer garment 10 is an undershirt, the baselayer garment 10 may be any other baselayer garment in other embodiments. For example, in some embodiments, the baselayer garment 10 may be underpants (e.g., shorts or a cup supporter) configured to be worn under protective pants (e.g., protective shorts), a sock configured to be worn under a shin guard, a compression sleeve (e.g., arm or shin sleeve) configured to be worn under an arm pad (e.g., an elbow pad) or a leg pad, or a head cap configured to be worn under a helmet.
While in this embodiment the athletic garment 10 is configured to be worn under the protective athletic equipment 12, the athletic garment 10 may be configured to be worn over the protective athletic equipment 12 in other embodiments. For example, in some embodiments, the athletic garment 10 may be a jersey (e.g., a team jersey) configured to be worn over the protective athletic equipment 12.
2. Protective athletic equipment
The shoulder pads 13 protect various regions of the player's upper body. As shown in Figures 56 and 57, the player's thorax has a front side FS and a back side BS. The front side FS of the player's thorax, which can also be referred to as a "chest" or "ventral" side, comprises left and right pectoral regions LPR, RPR overlying left and right pectoral muscles of the player and a sternum region SR overlying a sternum of the player. The back side BS of the player's thorax, which can also be referred to as a "dorsal" side, comprises a thoracic spinal region TSR overlying thoracic vertebrae of the player, left and right trapezius regions LTR, RTR overlying left and right trapezius muscles of the player, and left and right latissimus dorsi regions LLR, RLR overlying left and right latissimus dorsi muscles of the player. Each of the player's shoulders has a clavicle region CR, a scapular region BR, an acromioclavicular joint region ACR, and a deltoid region DR respectively overlying a clavicle, a scapula, an acromioclavicular joint, and a deltoid muscle of that shoulder.
The shoulder pads 13 comprise an inner surface 23 for facing towards the player and an outer surface 25 for facing away from the player. In this embodiment in which the shoulder pads 13 are to be worn over the shirt 10, the inner surface 23 of the shoulder pads 13 is configured to contact the outer surface 19 of the shirt 10. The shoulder pads 13 comprise a front 54, a back 55, left and right shoulder arches 56i, 562, and left and right shoulder protectors 57i, 572. The front 54, the
back 55, and the shoulder arches 56i, 562 define a neck opening 58 for receiving the player's neck. In this embodiment, the shoulder pads 13 also comprise left and right upper arm protectors 59i , 592. The front 54 of the shoulder pads 13 is configured to cover at least part of the front side FS of the player's thorax. In this embodiment, the front 54 of the shoulder pads 13 comprises left and right pectoral portions 72i, 722 for covering the left and right pectoral regions LPR, RPR of the player, a sternum portion 73 for covering the sternum region SR of the player, and a top edge 74 delimiting the neck opening 58.
In this embodiment, with additional reference to Figure 22, the front 54 of the shoulder pads 13 comprises protective padding 75 disposed between an inner liner 76 and an outer covering 77. The protective padding 75 provides padded protection to the left and right pectoral regions LPR, RPR and the sternum region SR of the player. The protective padding 75 comprises a shock-absorbing material 47. For instance, in some examples of implementation, the shock- absorbing material 47 may comprise foam, such as ethylene vinyl acetate (EVA) foam, expanded polypropylene (EPP) foam, expanded polyethylene (EPE) foam (e.g., low-density polyethylene (LDPE) foam), vinyl nitrile (VN) foam, or any other suitable foam, or any other shock-absorbing substance other than foam (e.g., a gel).
The outer covering 77 of the front 54 of the shoulder pads 13 faces away from the player's body. The outer covering 77 comprises a material 78 making up at least part of the outer covering 77. That is, the outer covering 77 is at least partly (i.e., partly or entirely) made of the material 78. For instance, in some embodiments, the material 78 may be a flexible material (e.g., a woven fabric, a polyurethane or other elastomeric layer, etc.). In other embodiments, the material 78 may be a rigid material (e.g., polycarbonate, high-density polyethylene (HDPE), polypropylene, etc.) that forms a rigid shell.
The inner liner 76 of the front 54 of the shoulder pads 13 faces the player's body. More particularly, in this embodiment, the inner liner 76 faces and engages the shirt 10. The inner liner 76 comprises a material 80 making up at least part of the inner liner 76. That is, the inner liner 76 is at least partly (i.e., partly or entirely) made of the material 80. In this embodiment, the inner liner 76 is at least mainly (i.e., mainly or entirely) made of the material 80.
In this embodiment, with additional reference to Figures 23 and 24, the material 80 of the inner liner 76 of the front 54 of the shoulder pads 13 is a fabric. The fabric 80 is a thin pliable material comprising a fibrous base substance 81 including fibers 82I-82R arranged in a network by weaving, felting, knitting, interlacing, or otherwise crossing them. The fibers 82I-82R may include any suitable natural or synthetic fibers (e.g., polyester, nylon, spandex (elastane), or other fibers, or blends of these fibers). In this embodiment, the fabric 80 includes yarns 83ι-83τ that comprise respective ones of the fibers 82I-82R. More particularly, in this embodiment, the fabric 80 is a woven or knit fabric.
For example, in this embodiment, the fibers 82I-82R of the fabric 80 of the inner liner 76 include polyester fibers. For instance, the fabric 80 may comprise different types of polyester fibers (e.g., the fabric 80 may comprise 51 % 75D/48F textured polyester and 49% 50D/72F polyester and weigh 120 g/m2). The fabric 80 may have any other suitable composition in other embodiments. The fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 is configured taking into account movements of the player. In this example, the fabric 80 is also configured taking into account an interface between the shirt 10 and the shoulder pads 13. For instance, in this embodiment, the fabric 80 has mechanical properties to resist tearing or other excessive damage due to movements of the player and/or friction or other contact between the shirt 10 and the shoulder pads 13.
In this embodiment, the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 is a quick-drying material, i.e., a material exhibiting a drying rate which is relatively high, to quickly evaporate moisture as the player sweats. In this example, at least some liquid moisture evaporated by the fabric 80 may have been transported to the inner liner 76 by the shirt 10 which wicked this liquid moisture away from the wearer's body. For example, in some embodiments, the drying rate of the fabric 80 may be at least 2.1 ml/hr, in some cases at least 2.3, in some cases at least 2.5, and in some cases even more, according to AATCC Test Method 201 of the American Association of Textile Chemists and Colorists (AATCC). Alternatively or additionally, in some embodiments, the drying rate of the fabric 80 may be at least 15 ml/hr, in some cases at least 20 ml/hr, in some cases at least 25 ml/hr, and in some cases even more, according to AATCC Test Method 200 of the AATCC. The drying rate of the fabric 80 may have any other suitable value in other embodiments.
More particularly, in this embodiment, to facilitate moisture evaporation, the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 is configured to (1 ) spread moisture over a large surface area and (2) harness heat generated by the player's body to vaporize liquid moisture.
For example, in some embodiments, a surface area of the fabric 80 may be at least 300 cm2 per square centimeter of fabric, in some cases at least 400 cm2 per square centimeter of fabric, in some cases at least 500 cm2 per square centimeter of fabric, in some cases at least 600 cm2 per square centimeter of fabric, and in some cases even more. Alternatively or additionally, in some embodiments, a surface area of a constituent of the fabric 80 may be at least 200 m2 per gram of the constituent, in some cases at least 400 m2 per gram of the constituent, in some cases at least 600 m2 per gram of the constituent, in some cases at least 800 m2 per gram of the constituent, in some cases at least 1000 m2 per gram of the constituent and in some cases even more. The surface area
of the constituent of the fabric 80 may have any other suitable value in other embodiments.
To harness heat generated by the player's body to vaporize moisture, a constituent of the fabric 80 captures this heat to raise its temperature and cause vaporization of liquid moisture in contact with it. For example, in some embodiments, a specific heat capacity of a constituent of the fabric 80 (i.e., an amount of heat required to increase the temperature of a unit mass of the constituent of the fabric 80 by one degree) may be relatively low. For instance, in some embodiments, the specific heat capacity of the constituent of the fabric 80 may be less than polyester's specific heat capacity. The specific heat capacity of the constituent of the fabric 80 may have any other suitable value in other embodiments. Additionally or alternatively, in some embodiments, a molar absorptivity at an infrared wavelength of a constituent of the fabric 80 (i.e., a measurement of how strongly a chemical species of the constituent of the fabric 80 absorbs electromagnetic radiation at the infrared wavelength) may be relatively high. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the constituent of the fabric 80 may be greater than polyester's molar absorptivity at that infrared wavelength. The molar absorptivity at the infrared wavelength of the constituent of the fabric 80 may have any other suitable value in other embodiments.
Also, in some embodiments, a constituent of the fabric 80 may be configured to manifest an exothermic reaction releasing heat to accelerate the drying process. That is, a constituent of the fabric 80 may be configured to exothermically react (i.e., produce heat when reacting) with liquid moisture. The exothermic reaction may be chemical and/or physical. For example, in some embodiments, the exothermic reaction manifested by the constituent of the fabric 80 may be adsorption of liquid moisture by the constituent of the fabric 80, such that heat is released when the liquid moisture is adsorbed by the constituent of the fabric 80.
In this embodiment, the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 comprises active elements 84I-84E to manage moisture as the player sweats, including to enhance evaporation of liquid moisture in the fabric 80. The active elements 84I-84E are "active" in that they have a property allowing them to induce a chemical and/or physical reaction in response to a stimulus at their surface. In this example, this reaction induced by the active elements 84i- 84E helps accelerate the drying process of the fabric 80. The fabric 80 thus dries faster than if the active elements 84I-84E were omitted but the fabric 80 was otherwise identical (i.e., dries faster than a comparative fabric identical to the fabric 80 but without the active elements 84I-84E).
In this example of implementation, the active elements 84I-84E are connected to the fibers 82I-82R of the fibrous base substance 81 . In other examples of implementation, the fibers 82I-82R of the fabric 80 may themselves be the active elements 84I-84E that enhance the drying process of the fabric 80 on their own, without having distinct active elements connected to the fibers 82I-82R.
More particularly, in this embodiment, the active elements 84I-84E are active particles distributed within the fabric 80. In this example, the active particles 84i- 84E have an adsorptive property that causes them to adsorb liquid moisture as the player sweats. This reaction, i.e., adsorption, caused by the active particles 84I-84E helps evaporating the liquid moisture.
With additional reference to Figure 25, in this embodiment, each of the active particles 84I-84E is a microporous particle that includes a multitude of pores 85i- 85L (e.g., several thousands of pores) which can trap the liquid moisture.
Because of their pores 85I-85L, the active particles 84I-84E have a surface area which is very large, thereby vastly spreading the liquid moisture to aid evaporating it. For example, in some embodiments, the surface area of the active particles 84I-84E may be such that the surface area of the fabric 80 is at least
300 cm2 per square centimeter of fabric, in some cases at least 400 cm2 per square centimeter of fabric, in some cases at least 500 cm2 per square centimeter of fabric, in some cases at least 600 cm2 per square centimeter of fabric, and in some cases even more. Alternatively or additionally, in some embodiments, the surface area of the active particles 84I-84E may be at least 200 m2 per gram of active particle, in some cases at least 400 m2 per gram of active particle, in some cases at least 600 m2 per gram of active particle, in some cases at least 800 m2 per gram of active particle, in some cases at least 1000 m2 per gram of active particle and in some cases even more. The surface area of the active particles 84I-84E may have any other suitable value in other embodiments.
Also, in this embodiment, the active particles 84I-84E use heat generated by the player's body to vaporize moisture. For example, in some embodiments, a specific heat capacity of the active particles 84I-84E may be relatively low. For instance, in some embodiments, the specific heat capacity of the active particles 84I-84E may be less than a specific heat capacity of the fibrous base substance 81 of the fabric 80. Thus, in this example, the specific heat capacity of the active particles 84I-84E may be less than polyester's specific heat capacity.. The specific heat capacity of the active particles 84I-84E may have any other suitable value in other embodiments. Additionally or alternatively, in some embodiments, a molar absorptivity at an infrared wavelength of the active particles 84I-84E may be relatively high. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the active particles 84I-84E may be greater than a molar absorptivity at that infrared wavelength of the fibrous base substance 81 of the fabric 80. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the active particles 84I-84E may be greater than polyester's molar absorptivity at that infrared wavelength.. The molar absorptivity at the infrared wavelength of the active particles 84I-84E may have any other suitable value in other embodiments.
Furthermore, the adsorption of liquid moisture by the active particles 84I-84E is an exothermic reaction releasing heat that helps to accelerate the drying process. The active particles 84I-84E may be implemented in any suitable way. In this embodiment, the active particles 84I-84E comprise activated carbon. The activated carbon may be produced in various known ways. For instance, the activated carbon may be produced from carbonaceous materials such as wood, nutshells, coconut husk, coir, peat, lignite, coal, or other carbonaceous substances using known processes (e.g., physical reactivation using hot gases which involves carbonization and/or oxidation, or chemical activation using chemicals on raw material prior to carbonization), or synthetically using known processes (e.g., pyrolysis of polystyrene beads). In other embodiments, the active particles 84I-84E may comprise activated alumina (aluminum oxide), silica gel, soda ash, aluminum trihydrate, baking soda, cinoxate (p-methoxy-2- ethoxyethyl ester cinnamic acid), zinc oxide, zeolites, titanium dioxide, or any other suitable material.
The active particles 84I-84E may be incorporated into the fabric 80 using any suitable process. For example, in some embodiments, the active particles 84i- 84E may be joined to the fibrous base substance 81 of the fabric 80 using: an air dispersion process in which the active particles are entrained in a gaseous carrier onto the fibrous base substance 81 of the fabric 80 where they are fixed; a padding process in which the fibrous base substance 81 of the fabric 80 is passed through a bath of the active particles; a liquid suspension or mixture of a binder and the active particles applied to the fibrous base substance 81 of the fabric 80; or a xerographic process using electrostatic or magnetic attraction to transfer a toner formulation including the active particles towards the fibrous base substance 81 of the fabric 80. In some cases, a protective substance may be provided onto the active particles 84I-84E to protect these active particles during manufacturing of the fabric 80 and subsequently removed. Examples of such
processes are described in U.S. Patent 6,998,155, U.S. Patent Application Publication 2008/0121 141 and U.S. Patent 7,247,374, which are incorporated by reference herein. Examples of materials that can be used for the fabric 80 including the active particles 84I-84E may be commercially obtained from Cocona Inc., Boulder, Colorado.
The back 55 of the shoulder pads 13 is configured to cover at least part of the back side BS of the player's thorax. In this embodiment, the back 55 of the shoulder pads 13 comprises a spinal portion 85 for covering the thoracic spinal region TSR of the player, left and right trapezius portions 881 , 882 for covering the left and right trapezius regions LTR, RTR of the player, left and right latissimus dorsi portions 89i , 892 for covering the left and right latissimus dorsi regions LLR, RLR of the player, and a top edge 89 delimiting the neck opening 58.
In this embodiment, with additional reference to Figure 26, the back 55 of the shoulder pads 13 comprises protective padding 90 disposed between an inner liner 91 and an outer covering 92. The protective padding 90 provides padded protection to the thoracic spinal region SR, the left and right trapezius regions LTR, RTR, and left and right latissimus dorsi regions LLR, RLR of the player. The inner liner 91 faces the player's body, while the outer covering 92 faces away from the player's body. In this example of implementation, these components of the back 55 of the shoulder pads 13 may be constructed similarly to the protective padding 75, the inner liner 76, and the outer covering 77 of the front 54 of the shoulder pads 13. Notably, in this embodiment, the inner liner 91 of the back 55 of the shoulder pads 13 comprises a quick-drying fabric 180 like the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 (e.g., including active elements such as the active particles 84I-84E of the fabric 80).
The left and right shoulder arches 56i , 562 are configured to respectively arch over the left and right shoulders of the player and interconnect the front 54 and the back 55 of the shoulder pads 1 3. In this embodiment, with additional reference to Figure 27, each of the shoulder arches 56i, 562 comprises protective padding 93 disposed between an inner liner 94 and an outer covering 95. The protective padding 93 provides padded protection, the inner liner 94 faces the player's body, and the outer covering 95 faces away from the player's body. In this example of implementation, these components of each of the shoulder arches 56i , 562 may be constructed similarly to the protective padding 75, the inner liner 76, and the outer covering 77 of the front 54 of the shoulder pads 1 3. Notably, in this embodiment, the inner liner 94 of each of the shoulder arches 56i , 562 comprises a quick-drying fabric 280 like the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 1 3 (e.g., including active elements such as the active particles 84I -84E of the fabric 80) .
The shoulder protectors 57i , 572 are configured to respectively cover at least part of the left and right shoulders of the player. In this embodiment, each of the shoulder protectors 57i , 572 comprises an acromioclavicular joint portion and a deltoid portion for respectively covering at least part of the acromioclavicular joint region ACR and the deltoid region DR of the shoulder it protects.
Each shoulder protector 57x is connected to at least one of the front 54, the back 55, and a given one of the shoulder arches 56i , 562. In this embodiment, the shoulder protector 57x, is connected to the shoulder arch 56x arching over the shoulder that it protects. Also, in this embodiment, the shoulder protector 57x is connected to the arm protector 59x which is on the arm extending from the shoulder it protects. The shoulder protector 57x may be directly connected (e.g., sewed) to the shoulder arch 56x and/or the arm protector 59x or may be indirectly connected (e.g., via one or more straps sewed) to the shoulder arch 56x and/or the arm protector 59x.
In this embodiment, with additional reference to Figure 28, the shoulder protector 57x comprises protective padding 96 disposed between an inner liner 97 and an outer covering 98. The protective padding 96 provides padded protection, the inner liner 97 faces the player's body, and the outer covering 98 faces away from the player's body. In this example of implementation, these components of the shoulder protector 57x may be constructed similarly to the protective padding 75, the inner liner 76, and the outer covering 77 of the front 54 of the shoulder pads 1 3. Notably, in this embodiment, the inner liner 97 of the shoulder protector 57x comprises a quick-drying fabric 380 like the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 1 3 (e.g., including active elements such as the active particles 84I -84E of the fabric 80) .
The upper arm protectors 59i , 592 are configured to cover at least part of the left and right arms of the player. Each of the upper arm protectors 59i , 592 comprises an outer arm portion for overlying an outer region of the arm it protects and a strap for retaining itself on the arm.
In this embodiment, with additional reference to Figure 29, each upper arm protector 59x comprises protective padding 99 disposed between an inner liner 1 00 and an outer covering 1 01 . The protective padding 99 provides padded protection, the inner liner 1 00 faces the player's body, and the outer covering 1 01 faces away from the player's body. In this example of implementation, these components of the upper arm protector 59x may be constructed similarly to the protective padding 75, the inner liner 76, and the outer covering 77 of the front 54 of the shoulder pads 1 3. Notably, in this embodiment, the inner liner 97 of the upper arm protector 59x comprises a quick-drying fabric 480 like the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 1 3 (e.g., including active elements such as the active particles 84I -84E of the fabric 80).
While the shoulder pads 30 are constructed in a particular way in this embodiment, the shoulder pads 30 may be constructed in various other ways in other embodiments. For example, in some embodiments, as shown in Figures 30 and 31 , the drying rate of the shoulder pads 1 3 may differ over a plurality of areas 1 60I-160H of the shoulder pads 1 3. That is, the drying rate of a given one of the areas 1 60I-1 60H of the shoulder pads 1 3 may be different from (i.e., greater or lesser than) the drying rate of another one of the areas 1 60I-160H of the shoulder pads 1 3. For instance, the drying rate of a first one of the areas 1 60I-160H of the shoulder pads 1 3 that is disposed to overlie a first region of the player's body which is expected to generate more sweat may be greater than the drying rate of a second one of the areas 1 60I-160H of the shoulder pads 13 that is disposed to overlie a second region of the player's body which is expected to generate less sweat.
In this embodiment, the area 1 60i of the shoulder pads 1 3 is an area of the front 54 of the shoulder pads 1 3 that is disposed to overlie a chest region of the player's torso, the area I 6O2 of the shoulder pads 13 is an area of the back of the shoulder pads 13 that is disposed to overlie a back region of the player's torso, and the areas I 6O3, 1 604 of the shoulder pads 13 are areas of the shoulder protectors 57i , 572 that are disposed to overlie shoulder regions of the player's torso. As an example, the drying rate of the areas I 6O1 , I 6O2 of the shoulder pads 13, which are overlying regions of the player's body which may generate more sweat, may be greater than the drying rate of the areas I 6O3, 1 604 of the shoulder pads 1 3, which are overlying regions of the player's body which may generate less sweat. As another example, the drying rate of the area I 6O2 of the back 55 of the shoulder pads 1 3, which overlies the back region of the player's body, may be greater than the drying rate of the area I 6O1 of the front 54 of the
shoulder pads 1 3, which overlies the front region of the player's body that may generate less sweat than the back region of the player's body.
For example, in some embodiments, a ratio of (i) the drying rate of a given area 1 60i of the shoulder pads 1 3 over (ii) the drying rate of another area 1 60j of the shoulder pads 1 3 may be at least 1 .1 , in some cases at least 1 .2, in some cases at least 1 .3, in some cases at least 1 .4, in some cases at least 1 .5, and in some cases even more (e.g., 2 or more). The difference between the drying rate of respective ones of the areas 1 60I - 1 60H of the shoulder pads 1 3 may take on any other suitable value in other embodiments.
The variation of the drying rate over the areas 1 60I -1 60H of the shoulder pads 1 3 can be implemented in any suitable manner. In this embodiment, this may be achieved by varying a concentration or loading of active particles of a fabric, such as the active particles 84I -84E of the fabric 80 of the front 54 of the shoulder pads 1 3 and similar active particles of the fabric of other parts of the shoulder pads 1 3, over the areas 1 60I -1 60H of the shoulder pads 1 3. The concentration or loading of the active particles of the fabric in a given area 1 60i of the shoulder pads may be greater than the concentration or loading of the active particles of the fabric in another area 1 60j of the shoulder pads 1 3 such that the drying rate of the area 1 60i of the shoulder pads 1 3 is greater than the drying rate of the area 1 60j of the shoulder pads 1 3. For example, in some embodiments, a ratio of (i) the concentration or loading of the active particles of the fabric in the given area 1 60i of the shoulder pads 1 3 over (ii) the concentration or loading of the active particles of the fabric in the other area 1 60j of the shoulder pads 1 3 may be at least 1 .1 , in some cases at least 1 .2, in some cases at least 1 .5, in some cases at least 2, in some cases at least 4, and in some cases even more (e.g., 8 or more). The concentration or loading of the active particles of the fabric in a particular area 1 60x of the shoulder pads 1 3 can be measured as a weight percent of the active particles in that particular area 1 60x of the shoulder pads 1 3, i.e., a weight of the active particles in the area 1 60x of the shoulder pads 1 3
divided by a total weight of the fabric of the area 1 60x of the shoulder pads 1 3 and multiplied by one hundred. In some examples of implementation, an area 1 60x of the shoulder pads 1 3 may be free of active particles, i.e., there is no active particle in the area 1 60x of the shoulder pads 1 3, such that the concentration or loading of the active particles of the fabric in the area 1 60x of the shoulder pads 1 3 is substantially zero. The variation of the drying rate over the areas 1 60I - 1 60H of the shoulder pads 1 3 can be implemented in other ways in other embodiments (e.g., by varying a yarn size or fabric weight in different areas).
In some embodiments, the drying rate of a given area of the shirt 1 0 may be different from the drying rate of an overlapping area of the shoulder pads 1 3 which overlaps the given area of the shirt 1 0. For example, in some embodiments, the drying rate of the given area of the shirt 1 0 may be greater than the drying rate of the overlapping area of the shoulder pads 1 3 since the shirt 1 0 is more directly exposed to the player's sweat. For instance, in this example of implementation, the concentration or loading of the active particles of the fabric in the given area of the shirt 1 0 may be greater than the concentration or loading of the active particles of the fabric in the overlapping area of the shoulder pads 1 3 such that the drying rate of the given area of the shirt 1 0 is greater than the drying rate of the overlapping area of the shoulder pads 1 3. For example, in some embodiments, a ratio of (i) the concentration or loading of the active particles of the fabric in the given area of the shirt 1 0 over (ii) the concentration or loading of the active particles of the fabric in the overlapping area of the shoulder pads 1 3 may be at least 1 .1 , in some cases at least 1 .2, in some cases at least 1 .5, in some cases at least 2, in some cases at least 4, and in some cases even more (e.g., 8 or more).
To further enhance moisture management, in some embodiments, with additional reference to Figures 32 to 34, in addition to comprising a quick-drying material (i.e., the fabric 80 of the front 54 of the shoulder pads 1 3 and similar fabrics of
other parts of the shoulder pads 1 3 in this embodiment), the shoulder pads 13 may comprise a cooling material 1 65 providing a cooling effect perceivable by the player. As the quick-drying material works to accelerate moisture evaporation to help dry the shoulder pads 1 3, the cooling material 1 65 may help the player feel cooler. This may be particularly useful in a portion of the shoulder pads 13 contacting the player's body (e.g., in cases where the shirt 1 0 is not worn or another shirt covering less of the player's body is worn).
In this embodiment, the cooling material 1 65 is a fabric. The cooling fabric 1 65 comprises a fibrous base substance 137 including fibers 1 33ι-1 33κ, which may include any suitable natural or synthetic fibers (e.g., polyester, nylon, spandex (elastane), or other fibers, or blends of these fibers). In this example, the cooling fabric 1 65 is a woven fabric. The cooling effect provided by the cooling fabric 1 65 may be implemented in any suitable way. In this embodiment, the cooling fabric 1 65 comprises active elements 1 70i-1 70c to generate the cooling effect. More particularly, in this embodiment, the active elements 170i-170c are connected to the fibers 1 33i- 1 33K of the fibrous base substance 1 37. For example, in some embodiments, the cooling fabric 1 65 may be configured to cool down when absorbing moisture as the player sweats, i.e., a moisture-activated cooling fabric. For instance, the active elements 1 70i-170c may be swellable elements configured to swell when absorbing moisture to create the cooling effect. Examples of materials that can be used for the cooling fabric 1 65 that is moisture-activated are fabrics including Nexar™ polymers which may be commercially obtained from Kraton Performance Polymers Inc., Houston, Texas. As another example, in some embodiments, the cooling fabric 1 65 may be configured to cool down when absorbing heat from the player's body, i.e., a heat-activated cooling fabric. For instance, the active elements 1 70i-170c may be phase-change material (PCM) elements (e.g., microencapsulated PCM elements) configured to change phase when absorbing heat to create the cooling effect. Examples of materials that can
be used for the cooling fabric 1 65 that is heat-activated are fabrics including Thermocules™ PCM elements which may be commercially obtained from Outlast Technologies LLC, Boulder, Colorado. In other embodiments, the fibers 1 33i- 1 33K of the cooling fabric 1 65 may themselves be the active elements 1 70i-170c that generate the cooling effect on their own, without having distinct active elements connected to the fibers 1 33ι-133κ of the fibrous base substance 1 37. For instance, the fibers 1 33ι-1 33κ of the cooling fabric 1 65 may be configured to cool down when absorbing and trapping moisture inside them as the player sweats. Examples of materials that can be used for this purpose may be commercially obtained from CoolCore, Portsmouth, New Hampshire. Other examples of materials that can be used for the cooling fabric 1 65 may include IceFil by Ventex, Luxicool, Cool Jade, Advansa's Thermo Cool, and HeiQ's Adaptive. The quick-drying material (i.e., the fabric 80 of the front 54 of the shoulder pads 1 3 and similar fabrics of other parts of the shoulder pads 1 3 in this embodiment) and the cooling fabric 1 65 may be arranged in any suitable manner in the shoulder pads 1 3. For example, in this embodiment, a quantity of the quick- drying material in the shoulder pads 1 3 is greater than a quantity of the cooling fabric 1 65 in the shoulder pads 1 3. For instance, in this embodiment, the cooling fabric 1 65 may be present only in a limited area of the shoulder pads 1 3 where the cooling effect may be better perceived by the player. Thus, in this embodiment, the cooling fabric 1 65 is present in a quick-cooling spot of the player's body, i.e., a spot of the player's body that is more efficient at cooling. In this example, the cooling fabric 165 is disposed about the neck opening 58 since the cooling effect at the player's neck may be well perceived by the player. In other examples, the cooling fabric 165 may be disposed in other quick-cooling spots of the player's body (e.g., a crook of the elbow, a wrist, a forehead, an inner thigh, a bend of the knee, or an ankle).
In some embodiments, a fabric of an inner liner of the shoulder pads 1 3 (e.g., the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 or a similar fabric of another inner liner of the shoulder pads 13) may be a quick-drying and cooling fabric. That is, the fabric may be configured such that (1 ) its drying rate is relatively high and (2) it provides a cooling effect perceivable by the player. For example, in some embodiments, as shown in Figures 35 and 36, the fabric 80 of the front 54 of the shoulder pads 1 3 may comprise (1 ) the active elements 84i- 84E for quick-drying and (2) the active elements 1 70i-170c for the cooling effect connected to the fibrous base substance 81 . This may be done by applying the active elements 84I-84E and the active elements 1 70i-1 70c to the fibrous base substance 81 in a common process or sequential processes using known techniques (e.g., from companies mentioned above) to provide these elements in fabrics. In some embodiments, as shown in Figure 51 and 52, the shoulder pads 1 3 may comprise vents 1 66I-166F for ventilation. Facilitating air circulation may further enhance the quick-drying capability of the shoulder pads 1 3. Each of the vents 1 66-1-166F allows a greater air flow than parts of the shoulder pads 1 3 outside of the vents 166I-166F.
More particularly, in this embodiment, each of the vents 1 66I-166F comprises a an opening 1 63 and a mesh material 263 (i.e., a material having an open texture) disposed within the opening 1 63 for ventilation. In this example, the vents 166i- 1 66F are respectively located in front and back areas of the shoulder pads 13. The vents 166I-166F may be disposed in any other suitable manner in other examples.
In some embodiments, as shown in Figure 53, a vent 1 66i of the shoulder pads 1 3 may overlap a vent 66i of the shirt 1 0. This may further facilitate air flow though the athletic gear 1 1 . For instance, in some embodiments, such as shown
in Figures 49 to 52, each of the vents 1 665-166s in the back of the shoulder pads 1 3 may overlap a respective one of the vents 66s-66n in the back of the shirt 1 0.
The vents 1661-I 66F may be implemented in various other ways in other embodiments. For example, in some embodiments, a vent 1 66x may include the opening 1 63 without any mesh material in it (e.g., a through-hole extending through the shoulder pads 1 3). As another example, in some embodiments, as shown in Figures 54 and 55, a vent 1 66x may comprise a channel 257 to direct air flow in a particular direction or to a particular location (e.g., a particular location on the shirt 1 0 or the player's body that is expected to have more moisture). The channel 257 may extend within the shoulder pads 1 3, as shown in the embodiment of Figure 54, and/or may extend on an inner side 240 of the shoulder pads 1 3 as shown in the embodiment of Figure 55. In some embodiments, the shoulder pads 1 3 may comprise an indicator 1 71 to indicate a current quick-drying effectiveness of a quick-drying fabric (e.g., the fabric 80 of the front 54 of the shoulder pads 1 3 or a similar fabric of another part of the shoulder pads 1 3 in this embodiment). This "quick-drying effectiveness indicator" 1 71 may be useful in cases where the effectiveness of the fabric at quickly-drying itself can decrease (e.g., after the shoulder pads 1 3 have been repeatedly used or has been washed with a detergent) in order to allow the player to know when the shoulder pads 1 3 may no longer work as desired.
While in embodiments considered above the shoulder pads 1 3 comprise a quick- drying material that is a fabric making up at least part of an inner liner of the shoulder pads 1 3 (e.g., the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 1 3 or a similar fabric of another inner liner of the shoulder pads 1 3), in other embodiments, the shoulder pads 1 3 may comprise a quick-drying material that is another type of material making up another part of the shoulder pads 1 3. For example, in some embodiments, as shown in Figure 37, the shoulder pads 1 3 may comprise a quick-drying material 230 that is foam making
up protective padding 232 of the shoulder pads. For instance, the quick-drying foam 232 may comprise a cellular (i.e., foamed) base substance 267 (e.g., EVA, EPP, EPE, VN, PU or any other suitable cellular substance) and active elements 268-1 -268w, such as the active particles 84I -84E discussed above, connected to the cellular base substance 267 to enhance evaporation of liquid moisture in the foam 232. For example, in some embodiments, the protective padding 232 may be the protective padding 75 of the front 54 of the shoulder pads 1 3, the protective padding 90 of the back 55 of the shoulder pads 1 3, the protective padding 93 of each of the shoulder arches 56i , 562, the protective padding 96 of each of the shoulder protector 57i , 572, or the protective padding 99 of each of the upper arm protectors 59i, 592.
In some embodiments, the quick-drying material may be anti-microbial. For instance, in some embodiments in which it is a fabric, the quick-drying material may be treated (e.g., via a pad bath or exhaust process) or may have yarn-based anti-microbial or anti-odor technology.
The elbow pads 1 5i , 1 52 are wearable to protect the player's elbows and adjacent parts his/her arms. Each elbow pad 1 5x comprises an inner surface 1 23 for facing towards the player and an outer surface 1 25 for facing away from the player. In this example in which the elbow pad 1 5x is to be worn over the shirt 1 0, the inner surface 1 23 of the elbow pad 1 5x is configured to contact the outer surface 1 9 of the shirt 1 0. In this embodiment, with additional reference to Figure 38, each elbow pad 1 5x comprises protective padding 1 90 disposed between an inner liner 1 91 and an outer covering 1 92. The protective padding 1 90 provides padded protection to the elbow and adjacent parts of the player's arm. The inner liner 1 91 faces the player's body, while the outer covering 1 92 faces away from the player's body. In this example of implementation, these components of the elbow pad 1 5x may be constructed similarly to the protective padding 75, the inner liner 76, and the outer covering 77 of the front 54 of the shoulder pads 1 3. Notably, in this embodiment, the inner liner 1 91 of elbow pad 1 5x comprises a
quick-drying fabric 680 like the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 (e.g., including active elements such as the active particles 84I-84E of the fabric 80). Also, in this example of implementation, any feature or variant mentioned above in respect of the shoulder pads 13 (e.g., areas of different drying rates, inclusion of a cooling material, etc.) is applicable to the elbow pad 15x.
