When you need a reliable foundation for cold-weather adventures, the Patagonia Capilene Midweight Bottom delivers technical performance that moves with you from dawn patrol to après ski. This men's base layer features an innovative diamond-grid construction with hollow-core yarns that trap warm air close to your skin while actively wicking moisture away, keeping you comfortable whether you're skinning up for first tracks or settling into camp after a long day on the trail. The gusseted crotch and flatlock seams ensure unrestricted movement and chafe-free comfort during dynamic activities like climbing or backcountry skiing, while HeiQ Mint odor control technology keeps things fresh during multi-day expeditions when washing isn't an option. Built from 100% recycled polyester in a Fair Trade Certified factory, these midweight bottoms prove that high-performance outdoor gear can be both technically superior and environmentally conscious, making them the ideal choice for adventurers who demand excellence without compromise.
