an attachment unit which is attached to an edge part of the guide sheet and which is used to attach the guide sheet to the helmet,

wherein the air is made to flow through the air flow path by the at least one fan and the flowing air evaporates sweat coming out from the body to cool the body with heat of evaporation and in a case where the helmet is worn, the air which blows out from the air blow-out unit is guided to the helmet by the guide sheet and taken into the helmet from an air intake which is formed between an inner edge of the helmet and the head of the user in order to circulate the air inside the helmet, and

wherein the clothing main body includes a loose section at an upper back part thereof along a section from the at least one fan to the air blow-out unit, a range of the loose section extending from a center back part of the clothing main body onto the guide sheet, and the loose section being formed so as to make the clothing main body loose at the loose section and so that a distance between the loose section and the body or the underwear is larger than a distance between an area of the clothing main body other than the loose section and the body or the underwear, when the air is made to flow through the air flow path by the at least one fan.
