Patagonia Capilene 4 Expedition Weight Pants

The Patagonia Capilene 4 Expedition Weight Pants are the thickest and warmest baselayer in the Capilene® family. Polartec® Power Dry® High Efficiency™ fabric has a super-soft, stretchy feel designed with a smooth jersey face that glides beneath layers. This baselayer breathes, wicks perspiration, and dries in a flash, but also insulates well beneath layers at 20,000 feet for weeks on end.
