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 porous fluoropolymer membrane having an average ball burst load greater than 17 lb force, the porous fluoropolymer film having a colorized, oleophobic outer film surface, and an inner film surface opposite the outer film surface;
- and
- 2) 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, oleophobic outer film surface is the garment exterior film surface, the textile composite has a moisture vapor transmission rate greater than 4000 g/m2/24 hours, and the textile composite is abrasion resistant remaining 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 garment exterior film surface, and
- a laminate comprising
- 1) a porous fluoropolymer film having an abrasion resistant, colorized outer film surface, and inner film surface opposite the outer film surface, and an oil rating greater than 2, comprising a porous fluoropolymer membrane having an average maximum load in the transverse and longitudinal direction greater 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.
An outerwear garment having an abrasion resistant, low water pickup exterior film surface, comprising
- a garment exterior film surface, and
- a laminate comprising
- 1) a porous polymer film having an abrasion resistant, colorized outer film surface, and inner film surface opposite the outer film surface, and an oil rating greater than 2, comprising a membrane having an average maximum load in the transverse and longitudinal direction greater than 10 N, and
- 2) a knit or woven textile layer bonded to the porous polymer film by attachment adjacent to the inner film surface;
- the laminate having an MVTR greater than 4000 g/m2/24 hours and a mass per area less than 150 g/m2,
- wherein the outerwear garment is assembled so that the outer film surface of the laminate is the garment exterior film surface having a water pickup of less than 10 g/m2.
