WPB – Waterproof and breathable! Gore-Tex® is an excellent outdoor gear and clothing fabric. It is rugged and keeps you dry while allowing moisture vapor to escape.
The GORE-TEX® membrane: The secret of GORE-TEX® products — which are both completely waterproof and completely breathable at the same time — lies within its our revolutionary bi-component membrane. The membrane contains over 9 billion microscopic pores which are approximately 20,000 times smaller than a drop of water, but 700 times bigger than a molecule of moisture vapor. So while water in its liquid form cannot penetrate the GORE-TEX® membrane, as moisture vapor it can easily escape. – From the Gore-Tex website
