A low-temperature thermal insulation garment is proposed for low-energy requirement, self-sustaining body temperature maintenance. The proposed garment uses the body's expired respiratory gases and natural thermal production capabilities to insulate and maintain a comfortable skin temperature. The garment provides a constant re-supply of heated air with each exhaled breath. The garment has a mouthpiece with a check-valve that shunts exhaled air into a network of channels and bladders that cover the entire body. The garment also consists of a heat reflective lining to reduce radiant heat loss and a neoprene outer layer providing conductive insulation, durability, and waterproofing. Inhaled air is heated prior to entering the mouthpiece due to heat exchange with warmer areas of the garment. This allows residual heat from the exhalant to be transferred to incoming air. The garment can be fitted with artificial air supply, worn as is, or under a pressurized suit.

1. A heat recycling garment, worn to provide thermal protection to a wearer's body from low temperature environments, said garment utilizing the wearer's own expired respiratory gases to continuously transfer heat back to the wearer's body, via direct conductive heat transfer to the skin's surface, said garment further comprises a means for the continuous capture of the wearer's exhaled gases, and the controlled direction of the wearer's exhaled gases through a network of interconnected channels and bladders whose flow path extends from said means of gas capture over the entire body, extending to the hands and feet, and a means for the continuous controlled transfer of the gas's thermal energy back to the wearer's body surface.
