Patagonia Capilene Thermal Weight Boot Length Bottoms (Women's)

Built for cold conditions, these boot-length baselayer bottoms deliver warmth without the bulk. The Polartec® Power Grid® fabric—92% recycled polyester with a touch of spandex—traps heat, wicks moisture, and moves easily with you, while the smooth outer face makes layering simple. The open-grid interior adds loft and breathability, keeping you warm but never stifled, and HeiQ® Pure odor control helps them stay fresh over long days.

The fit is designed for movement, with a gusseted crotch and flatlock seams to minimize chafing. A flat waistband with brushed elastic sits comfortably against the skin, and the cropped 22" inseam sits above boots so there’s no bunching in your socks.

Made in a Fair Trade Certified™ factory, these bottoms balance performance, comfort, and responsibility. Lightweight, packable, and reliable, they’re the kind of baselayer you’ll reach for whenever the forecast turns cold.
