摘要： A portable water reservoir to be worn by a firefighter to provide a supply of water for use in extinguishing fires, e.g., the remnants of a forest or brushland fire, comprises a garment like body formed of an inner ply of flexible sheet material having a high resistance to rupture, puncture and delamination, and capable of being welded to itself such that the weld likewise has high resistance to rupture and delamination, the inner ply being doubled and welded to itself continuously along its free edges in a continuous wide weld to define therein a water-tight reservoir capable of holding several gallons of water; and an outer ply of flexible sheet material having high tensile and tear strength, shape retention, and resistance to heat, flame and hydrostatic pressure; the outer ply overlying and completely encompassing the inner ply and the reservoir defined thereby and being mechanically attached, preferably stitched or sewn, at its free marginal edges to and continuously along and solely within the continuous wide weld at the free edges of the inner ply, so that the integrity of the reservoir is preserved and the outer ply firmly supports and imparts strength and shape retention to the inner ply.
