ABSTRACT:
A water-vapor-permeable, water-resistant composite material includes a water-resistant, water-vapor-permeable functional layer with a first and a second side, a material attached to the first side of the functional layer, a plurality of discrete polymer spots forming a discontinuous, lining-producing pattern on the surface of the second side of the functional layer, and a water-vapor-permeable cover layer that is joined at least to the polymer spots. Clothing produced from the water-vapor-permeable, water-resistant composite material includes the features listed above.
