The Women's Patagonia R1 Thermal Bottom is a technical pant for alpine adventures. The smooth and durable outer face fabric glides when pulling a shell over top, and is capable of deterring wind and snow while hanging around camp. The soft microgrid fleece backing wicks moisture to keep you warm and comfortable while moving in cold conditions.
