Without a good base layer, the rest of your outfit isn’t able to function as designed. As the first barrier between your skin and the elements; it’s critical a good baselayer be warm, comfortable, and moisture-wicking. The Pyrex Extreme Pant has all those things in a durable, well cut package. The proprietary GRIDtech 4-way stretch fabric works as a second skin, providing additional warmth without weight and maximum breathability.
