I love a good wool suit, and I appreciate the fact that it’s a natural fiber. I know where it comes from, and I know how it’s bred. And it’s built to last. It breathes and it feels good. A lot of my climbing and hiking gear is all wool, because I can wear it for a week straight and it doesn’t smell. And when you get hot and sweaty in a cold temperature, it stays warm. So your body temperature stays at a good warmth rather than freezing your ass off.
