What is Gore-Tex® Fabric?
Gore-Tex® Fabric is a high performance fabric used in outdoor apparel to keep you dry and comfortable, even when exposed to extreme wet, windy and cold conditions. Gore-Tex® Fabric has a uniquely patented structure made up of two different substances. One is an ePTFE (expanded polytetrafluoroethlene) membrane, which is hydrophobic or water hating. It contains 9 billion pores per square inch. Liquid water cannot penetrate these pores, but moisture from perspiration can easily escape. Integrated into the membrane is an oleophobic or oil hating substance, which prevents penetration of contaminants that might affect waterproofness or breathability. The Gore-Tex® line also includes Dryloft® Fabric, Gore-Windstopper® Fabric, Activent® Fabric, and Gore-Tex® Immersion Technology® and Ocean Technology® Fabrics.
