On clearance from Galvin Green - the Apex Gore-Tex Jacket
The Gore-Tex membrane contains over 1.4 billion microscopic pores per square cm. These pores are 20,000 times smaller than a water droplet, but 700 times larger than a water vapour molecule, which makes the Gore-Tex membrane completely waterproof from the outside, while allowing moisture to escape from the inside.
