ABSTRACT:
A personal flotation apparatus is made of one or more layers of cross-linked polyethylene polymeric foam material. A nylon or polyester cloth preferably having a tight weave is fused to one or both of the inner or outer surfaces. When more than one layer is used the cloth may be fused to interfaces of both layers. Edge portions of the personal flotation apparatus are rounded inward and cloth fused to the outer surface is extended inward around the round edge to abut or overlap and be joined to cloth on an inner surface.
