How does Gore-Tex® Work?

When we buy skiing and snowboarding clothing, we all check it’s windproof, waterproof and breathable, because we want to stay warm and dry on the mountain.

Gore-Tex® is synonymous with windproofness, waterproofness and breathability! So how does Gore-Tex® stop water coming in, and at the same time let water out? Is it magic?

Gore-Tex® is a sandwich of Polytetrafluoroethene (PTFE) and Nylon layers, and the PTFE layer has millions of tiny holes in it. These holes are too small to let the snowy water droplets in, but big enough to let your sweaty water molecules out – clever eh!

Here’s a thought; does it matter which way round you have the Gore-Tex®?
