Move through crisp alpine mornings or push through demanding ascents with an almost imperceptible layer of support. The Brand REI Co-op Lightweight Base Layer Bottom - Women's is your foundation for unrestricted movement, whether navigating technical climbs or finding your rhythm on a frosty run. Crafted from a responsive blend of 84% recycled polyester and 16% spandex, this fabric actively moves moisture away from the skin, dries rapidly after exertion, and integrates a smart antimicrobial treatment to keep things fresh through multi-day excursions. Its smooth, stretchy feel and flatlock seams glide against the skin, eliminating any hint of chafing, while a gusseted design ensures a full, unhindered range of motion from scramble to stride. With reliable UPF 50+ protection and a brushed, soft-touch waist, it’s engineered for consistent comfort and confidence, performing perfectly beneath a shell on a high-altitude tour or as a standalone for an invigorating studio session, allowing full immersion in the moment.
