What is a GORE-TEX membrane?
GORE-TEX membranes are waferthin films that can be permeated by water vapour, not, however, by drops of water. This is because the pores of a GORE-TEX membrane are 20,000 times smaller than drops of water, but 700 times larger than the pores of water vapour.
How does a GORE-TEX membrane work?
How the GORE-TEX Membrane Works. Each microscopic pore is 20,000 times smaller than a water droplet, but 700 times larger than a water vapor molecule, resulting in a membrane that prevents water precipitation like rain and snow from penetrating through into your layers, but still allowing sweat vapor to escape.
Is GORE-TEX membrane waterproof?
Each of these tiny holes is 20,000 times smaller than a water droplet. This is what makes the membrane in everything in the original GORE-TEX products range waterproof: rain and snow simply cannot get in. Because the GORE-TEX membrane is also breathable, and windproof.
How long does GORE-TEX membrane last?
