ABSTRACT:
The subject invention is a buoyancy jacket constructed of a pair of separate buoyancy compartments overlying each other. There is an inner buoyancy compartment and an outer buoyancy compartment with the inner buoyancy compartment to be located directly adjacent the skin of the wearer of the jacket. Each of the buoyancy compartments are to be inflated by a separate inflation valve. The body of the jacket includes a plurality of baffles with each baffle including a small loop of sheet material. Each loop is to be fixedly connected between the outer layer of the jacket and the intermediate layer, and also between the inner layer of the jacket and the intermediate layer. It is the function of the loops to limit the expansion of the buoyancy compartments when inflated.
