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.
Wool is a 100% natural fiber, characterized by its flexibility and its insulating properties. Due to the structure of its fibre, it protects from cold as well as heat, and its absorption rate allows breathability. Mixed with cotton, the softness of the wool is increased; and mixed with synthetic fibers, it gains in ease of maintenance and durability.
