The Patagonia Women's Capilene 3 Midweight Baselayer Bottoms are designed to manage the extremes of high-output exertion in cool-to-cold conditions, our Capilene Midweight fabric hits the sweet spot of weight, breathability and wicking that, worn alone or with additional layers, is the essence of versatility. It keeps you dry and comfortable when worn during high-exertion activities in cool-to-moderate temperatures and insulates beneath a shell in cold weather. Constructed with a Polartec® Power Grid® fabric, it has a smooth face for easy layering and a brushed-back grid that aids in wicking as well as warmth. The fabric is bluesign® approved, has 66% recycled-polyester content and is treated with Polygiene® permanent odor control. Features include a flat waistband with brushed inner elastic for next-to-skin softness, a gusseted crotch for mobility and flatlock seams to minimize chafing.
