-14. (canceled)
An outerwear garment having an abrasion resistant exterior film surface, comprising
- a textile composite consisting essentially of
- 1) a first layer consisting essentially of a porous fluoropolymer film comprising a microporous PTFE membrane having an average ball burst load greater than 17 lb force, the porous fluoropolymer film having a colorized outer film surface having an oleophobic coating, and an inner film surface opposite the outer film surface;
- and
- 2) a second layer consisting essentially of a knit layer bonded to the porous fluoropolymer film by adhesive attachment adjacent to the inner film surface;
- wherein the outerwear garment is assembled so that the colorized outer film surface is the garment exterior film surface, the fabric composite has a moisture vapor transmission rate greater than 1000 g/m2/24 hours, and the laminate is durably water proof after more than 1400 abrasion movements on the outer film surface.

An outerwear garment having an abrasion resistant exterior film surface, comprising
- a laminate comprising
- (1) a porous PTFE film having a colorized outer film surface, and inner film surface opposite the outer film surface, and an oil rating greater than 2, comprising a microporous PTFE membrane having an average maximum load in the transverse and longitudinal direction greation than 10 N, and
- (2) a knit or woven textile layer bonded to the porous fluoropolymer film by attachment adjacent to the inner film surface;
- wherein the laminate has a mass per area less than 150 g/m2, and the outerwear garment is assembled so that the outer film surface of the laminate is the garment exterior film surface, and the outer film surface of the laminate is abrasion resistant.
