When not using the air supply/exhaust type coldproof clothing, the air is let out from the air supply/exhaust port, and the air supply/exhaust type coldproof clothing can be folded. The air supply/exhaust type coldproof clothing consists of only sheets on the rear side and the front side except the air supply/exhaust port and attachments for wearing the air supply/exhaust type clothing as clothing, and does not have a filler thereinside.
