Before putting on the inner cap, the user pre-stores the cooling member 100 in each of the three pockets 24. The user puts the cap portion 1 on his head. In the wearing state, the cap portion 1 is in a state of being inclined backward with the rear side being the lower side. The user wraps the neck portion 2 around the neck. The neck portion 2 is located below the ear. The user connects both ends of the neck portion 2 in the left-right direction with the hook-and-loop fastener 27. The left and right ends of the neck portion 2 are connected to each other at a position on the front side of the neck. The connecting portion of the neck portion 2 is located below the chin. When both ends of the neck portion 2 in the left-right direction are connected to each other, the neck portion 2 becomes an annular shape, and the neck portion 2 orbits the neck. Since the neck portion 2 has a band shape, the user can easily wrap the neck portion 2 around the neck.

When the neck portion 2 is attached to the neck, the cooling member 100 on the left side is located on the left side of the neck, the cooling member 100 on the right side is located on the right side of the neck, and the cooling member 100 in the center is located on the rear side of the neck. To do. Since the neck portion 2 has a band shape, the three cooling members 100 come into close contact with the neck via the neck portion 2. The cooling member 100 on the left side faces the side of the carotid artery 200 on the left side, and the cooling member 100 on the right side faces the side of the carotid artery 200 on the right side.

As described above, the left and right carotid arteries 200 can be directly cooled by the cooling members 100 housed in the left and right pockets 24. The carotid artery 200 is a blood vessel from the heart to the brain. Therefore, heat stroke can be effectively prevented by cooling the carotid artery 200 with the left and right cooling members 100. Since the cooling members 100 are symmetrically located on the left side and the right side of the neck, the left-right balance is excellent. Therefore, the neck portion 2 is less likely to be displaced, and the burden on the user is small. In addition, the central cooling member 100 can cool the rear part of the neck. Since the rectangular cooling member 100 is housed in the pocket 24 sideways, it has an excellent sense of stability. Further, the vertical dimension of the neck portion 2 is suppressed as compared with the configuration in which the cooling member 100 is vertically stored in the pocket 24. Therefore, the user can stably wrap the neck portion 2 around the neck.

Since the neck portion 2 is not separated from the cap portion 1, misalignment of the neck portion 2 in the circumferential direction can be easily prevented. Moreover, since the neck portion 2 is connected only to the rear portion of the cap portion 1, the user can easily move the head up, down, left and right. Even if the user moves his / her head, the neck portion 2 is unlikely to be displaced from the neck. Therefore, the cooling member 100 is unlikely to be displaced from the carotid artery 200 in the circumferential direction. In particular, since the length of the upper end portion 21a of the connecting piece portion 21 in the left-right direction is shorter than the diameter of the cap portion 1, the cap portion 1 is easy to move with respect to the neck portion 2. Since the neck portion 2 has the connecting piece portion 21, the front portion and the left and right side portions of the cap portion 1 can be easily separated from the neck portion 2 upward.
