The GORE-TEX® membrane is the heart of all GORE-TEX® products. It contains over
1.4 billion microscopic pores per square cm (9 billion per inch). These pores
are 20,000 times smaller than a water droplet, but 700 times larger than a water vapor molecule, which makes the GORE-TEX® membrane completely waterproof from the outside, while allowing perspira-tion to escape from the inside. In order to meet the specific needs of each end use,
W. L. Gore & Associates has developed different GORE-TEX® membranes and applies them as appropriate.
POLARTEC® POWER DRY® fabrics are designed to keep your skin dry when you sweat. All fabrics in this series feature a patented bi-component knit construction that used different yarns on either side of the fabric. This creates two different surfaces: one that is optimized to move moisture away from the skin, the other to dry quickly. POWER DRY® combined with technology Anti-UV, UPF 15 and + certified.
