The GORE-TEX® membrane is the heart of all GORE-TEX® products. It contains over 9 billion microscopic pores square 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 perspiration to escape from the inside. An oleophobic, or oil-hating, substance is integrated into the membrane, preventing the penetration of body oils and insect repellent that could otherwise affect the membrane



To construct a GORE-TEX® laminate, the GORE-TEX® membrane is bonded between high-performance fabrics that are extremely breathable. All GORE-TEX® fabrics are waterproof, windproof, and breathable. However, there are many different outer fabrics and fabric constructions available so that you can choose what's most important to you: weight, texture, abrasion resistance

Seams and stitching are essential aspects of a garment's construction. Unfortunately, they compromise the water and liquid protective properties of the fabric: seams and needle holes may be small, but they will still leak. That's why they must be completely sealed.

For absolute waterproofness and liquid resistance, gore-tex products rely on GORE-SEAM® TAPE. This unique tape, backed by reliable Gore equipment and know-how, ensures that every seam and tiny stitch hole is sealed.

The use of GORE-TEX® is tightly controlled to ensure its effectiveness.
