The Corwin Insulated Pant pairs perfectly with the warmest jackets like the Whitmer Down Parka to create an ultra-toasty system that feels balmy even when it’s downright frigid. 40g of 90% Recycled Polyfill throughout the pants provides ample warmth without feeling bulky or heavy, and the 10K/10K Oxford Weave fabric and CORDURA® reinforced cuffs stand up to endless days of cold-weather punishment.
