ABSTRACT:
The invention is directed to a layered fabric material that is breathable and has resistance to fluid penetration. The fabric has a lightweight, breathable outer layer and a layer of non-woven material. The non-woven material is breathable and fluid resistant. The fabric also includes a thermoplastic film having a plurality of perforations. The perforations form capillaries that extend from a surface of said film. The capillaries are disposed at an angle from about 5.degree. to about 60.degree. with respect to the surface of said film. The capillaries formed by the perforations allow the film layer to be breathable while resisting direct flow of liquid through the film.
