摘要

The survival clothing has a valve for the mouth (1) which passes exhaled air into a tube system (2) to warm or cool the body. Condensation is carried into a collection vessel (3), fitted with a controlled exhaust valve (4). The tube system is coated on one side so that warmth is directed at the body.
