| Abstract: |
Articles of clothing and the method of making the same which will allow water vapor due to perspiration to transpire through the article but will prevent liquid water from external sources from reaching the wearer's foot. The articles made by this method of the invention include socks and gloves which are of three-ply construction with the inside and outside plies being knit and the intermediate ply being made from an elastomeric polyurethane film. The three plies are uniquely bonded together using a pliant, waterproof adhesive to form a laminated article having specific elasticity characteristics.

I claim:
1. A method of making an article of apparel used to cover a wearer's extremities comprising the steps of:
- (a) depositing a heat activated adhesive on the surface of a stretchable, waterproof, breathable membrane of a first wall thickness to form a coated membrane;
- (b) forming said coated membrane into a bladder having a perimeter of a first size and an extremity receiving portion in the general shape of the wearer's extremity to be covered, said bladder having a smooth outer surface and a smooth inner surface generally conformable to the contours of the extremity to be covered;
- (c) placing said bladder over a first fabric member having a perimeter of a second size smaller than said first size and being in the general shape of the wearer's extremity to form an assemblage comprising said first fabric member and said bladder overlaying said first fabric member in an unstretched state; and
- (d) simultaneously heating and compressing said assemblage at a pressure sufficient to reduce the wall thickness of said bladder to form a composite comprising a thinned bladder with said first fabric member being securely bonded thereto, said composite being such that said thinned bladder can be stretched by at least 10 percent in at least one direction by a load less than that required to stretch said composite in at least one direction by the same amount.
