The super warm women’s Burton Expedition Pant is our most bomber base layer and a must-have for extremely cold conditions. The DRYRIDE Ultrawick™ Expedition 300 fabric is a force field that propels moisture away from your skin while keeping heat locked in. The women’s-specific contoured waistband feels like your favorite pair of yoga pants, while Stretch 360° mirrors your every move to prevent scrunching and bunching.
