ABSTRACT:
A flotation garment employs first and second sheets of a thermoplastic film bonded face to face along a rectilinear grid work of seams forming a spaced array of mutually isolated air cells, so that the garment will not substantially lose its buoyancy when a portion of the cells are punctured. The bonded seams are perforated at selected points to enable adequate ventilation.
