Gore-Tex is an amazing invention and used in all sorts of applications across many industries. I know what you’re thinking: Isn’t that just waterproof, and won’t I be hot? The short answer is no. Gore-Tex is designed to keep you comfortable in all climates. While Gore-Tex is a waterproof breathable membrane, it will also keep you from losing too much moisture in extreme conditions. Having too much air flow in extreme conditions may feel nice in the short term but can dehydrate you faster. Many manufactures use Gore-Tex in their touring and adventure gear such as the Klim Adventure Rally jacket pictured above.
