The Women’s Capilene Thermal Weight Bottoms are ideal as a baselayer for endurance activities in cold temperatures. These bottoms excel on trails, rivers, backcountry slopes and any other location that sees moderate exertion in chilly conditions. Designed to help you stay dry and warm beneath layers, the Thermal Weight Bottoms were fashioned with an open-grid pattern for superior warmth and moisture-wicking performance. The Men's Capilene Thermal Weight bottoms have a smooth faced exterior that glides easily beneath layers. Other features of these Patagonie Capilene Bottoms include a brushed elastic waistband for next-to-skin comfort and a gusseted crotch for unimpeded mobility. These Thermal Weight Baselayers were designed with flatlock seams to minimize chafing, and the fabric has HeiQ® Fresh to provide durable odor control. For cold weather environments, it just doesn't get any better than the Womens Patagonia Capilene Thermal Weight Bottoms!
