Abstract
A layered fabric for constructing action sportswear. The fabric generally comprises the following two layers: (1) a shell fabric comprised of a blend of polypropylene filaments and DORLASTAN.RTM. brand spandex fibers, and (2) a waterproof membrane laminated to the back of the shell fabric. Optionally, a third layer, a crepe or mesh lining, can be attached to the back of the membrane. The fabric has the qualities of being waterproof, breathable, and elastic and possess a number of other qualities which are highly desirable in action sportswear.

A layered fabric for use in constructing sports apparel comprising:
- a first layer comprised substantially of polypropylene filaments blended with elastomeric fibers, which layer substantially resists absorption of liquid water;
- and
- a second layer, laminated to said first layer, said second layer being impervious to liquid water but pervious to water vapor.
A dry suit for surfers constructed substantially of a layered fabric comprising:
- a first layer comprised substantially of polypropylene filaments blended with elastomeric fibers, which layer substantially resists absorption of liquid water;
- and,
- a second layer, laminated to said first layer, said second layer being impervious to liquid water but pervious to water vapor.
A layered fabric for use in constructing sports apparel comprising:
- two layers,
- a first said layer comprised substantially of polypropylene filaments blended with elastomeric fibers which layer substantially resists absorption of liquid water;
- and
- a second said layer, laminated directly to said first layer, said second layer being impervious to liquid water but pervious to water vapor.
A dry suit for surfers constructed substantially of a layered fabric comprising:
- two layers,
- a first said layer comprised substantially of polypropylene filaments blended with elastomeric fibers which layer substantially resists absorption of liquid water;
- and
- a second said layer, laminated directly to said first layer, said second layer being impervious to liquid water but pervious to water vapor.
A layered fabric for use in constructing sports apparel consisting essentially of:
- a first layer comprised substantially of polypropylene filaments blended with elastomeric fibers, which layer substantially resists absorption of liquid water;
- and
- a second layer, laminated to said first layer, said second layer being impervious to liquid water but pervious to water vapor.
