ABSTRACT:
Thick floatation pads for securement within the walls of floatation garments, such as life-saving vests and the like, are formed of stacks of aligned, relatively thin, flexible, resilient, foamed plastic sheets which are secured together along at least one edge. The sheets are substantially free of securement, one to another, between their edges. Thus, the sheets may relatively flex, move and bulge relative to each other for closely and comfortably conforming to the shape of the wearer's body and for tending to maintain maximum floatation volume at all times.
