An anti-exposure suit is disclosed that protects a wearer against environments characterized by extremely cold temperatures. The suit comprises a coverall type garment including an outer layer of lightweight fluid impervious material and an inner fluid impervious layer defining an air-tight bladder therebetween for injection of gas to form an insulative layer between the wearer and the surrounding environment. In a preferred embodiment of the suit the inwardly facing surface of both the inner layer and the outer layer are highly reflective to minimize the loss of radiant heat. A life vest including pockets adapted for in place injection of buoyant material may be provided as an integral part of the suit or provided separately as an overgarment as desired. The outwardly facing surface of the outer layer may be provided with a highly visible surface to facilitate location of a wearer during a search and rescue operation.

A survival suit comprising: an outer layer of lightweight gas and liquid impervious material adapted to cover substantially the entire body of a wearer; an inner layer of lightweight gas and liquid impervious material disposed within the outer layer and adapted to cover substantially the entire body

A survival suit comprising: an outer layer of lightweight gas and liquid impervious material adapted to cover substantially the entire body of a wearer; an inner layer of lightweight gas and liquid impervious material disposed within the outer layer and adapted to cover substantially the entire body of a wearer; said inner and outer layers selectively inter-connected to form a gas and liquid tight gas inflatable bladder therebetween; at least one of said layers having a highly reflective bladder facing surface to minimize radiant heat loss; means defining pockets selectively disposed on the suit and adapted to receive buoyant material to assure that a suit wearer floats in a upwardly facing orientation; and means providing a foaming reaction for producing a buoyant material for injection of said material into selected ones of said pockets.
