  Here, the air permeability of the lining is appropriately selected according to the use mode. For example, when an exhaust port is formed in the lining, it is preferable that the lining has a lower air permeability. On the contrary, when an exhaust port is not formed in the lining, it is preferable to increase air permeability and exhaust air through the lining fabric to fill the body with air.

  Such an exhaust port may be formed in the lining and / or the outer surface. At that time, a flap (a cloth covering the opening), a filter, a mesh cloth, a chuck (zipper), or the like may be attached to the exhaust port. For example, it is preferable to form the exhaust port only on the outer surface because air containing a strange odor or dust can be exhausted so as not to hit the face.
