Abstract: A waterproof glove formed of a flexible inner glove body providing a thermal plastic resin film on a base fabric and an flexible outer glove body of the same fabric is thermally unified after the former is inserted into the later. The glove can also be manufactured by a thermal adhesion of the flexible inner glove body providing outwardly the thermal plastic resin film and a flexible outer glove body providing inwardly the same resin film or by a thermal adhession of the flexible inner glove body coating outwardly a thermal plastic resin film having a lower melting point and a flexible outer glove body after insertion of the former into the later. A glove for a skier or a rider in which the thumb is freely movable to grip a stick or a handle, can be manufactured by thermal adhesion of a thumb portion and an other body portion of the glove which was manufactured separately from the same manner and same materials.
