ABSTRACT:
A cold weather buoyant garment has inner and outer layers with an intermediate layer therebetween. The intermediate layer is formed of a major portion of open cell foam material, such as polyurethane, with a minor portion of a closed cell material, such as polystyrene beads, uniformly dispersed in the open cell material. This composite intermediate layer exhibits good vapor transmission characteristics while simultaneously providing buoyancy characteristics sufficient to assist an individual immersed in cold water and wearing the garment to remain afloat.
