Women's base layers

603 products

A base layer is designed to wick sweat away from the skin, so it is worn tightly — a looser piece will do this job significantly worse.

FAQs

Use a three-layer system: 1) base layer (wicks away sweat), 2) mid layer (thermal insulation, fleece), 3) outer layer (waterproof and windproof membrane).
Follow the size chart with specific measurements. Functional clothing should fit comfortably and allow for free movement; insulating layers can fit more snugly.
Merino wool, technical synthetics (polyester/nylon), and membranes like Gore-Tex® offer the best performance, moisture wicking, and durability.
Wash on a gentle cycle with a detergent for sports clothing. Avoid fabric conditioner. Air dry and occasionally renew the water-repellent (DWR) treatment.
Premium membranes like Gore-Tex offer a higher hydrostatic head and durability, while cheaper alternatives focus more on breathability or low weight.
