Abstract : The patent concerns a protective garment to provide a unitary, lightweight, stretchable or elastic, multi-layer garment through which air is circulated without resort to tubes or conduits. A further advantage of this garment is that it employs a counter-current flow of air which functions both to reduce the temperature gradient between the internal and external environment to purge any toxic gases that may have leaked inboard of the garment before they can contact the body. Counter-current air flow, as the term is used, refers to the movement of a first layer of air over the surface of the body in one direction and the movement of a second layer of air external of the first layer in the opposite direction. The method of circulation results in an increase in velocity and turbulence of the ventilating air passing over the body which, in turn, results in increased efficiency of heat transfer and moisture pickup.
