| Abstract: |
A glove having three layers, an outer covering layer of leather, cloth or the like, an inner lining of an insulating material such as cloth, wool, fur and an intermediate member of a thin plastic having microscopically minute pores through which gas may pass but not liquids, e.g. water. The outer and inner layers are formed into gloves as by sewing. The intermediate layer of, for example, extremely thin polyurethane, is fabricated by heat sealing the edges of the front and back blank halves together to form an integral glove member. The intermediate glove layer is telescoped into the outer glove layer and similarly, the inner lining is telescoped into the intermediate layer. Only the outer and inner layers are stitched together at the wrist portion leaving a free-standing, breathable, waterproof intermediate layer therebetween which is integral and unattached. The resulting glove structure is water resistant and air permeable.
