Abstract
An atmospheric air pressure inflatable garment has an inner layer and outer layer define a confined space with a compressible material therein. The compressible material has resiliency and strength characteristics so that it compresses under atmospheric conditions when the air pressure in the confined space is reduced to sub-atmospheric pressure and an air passage adapted to permit passage of air into and out of the confined space but not water when a seal for sealing the passage is released. The garment is stored with the air removed and permitting atmospheric air to fill the space when the seal is opened raise the pressure in the space to atmospheric and causes the compressible material to expand separating the inner and outer layers and forming an insulation therebetween.
