Women's base layers
603 productsA 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.
Merino keeps you warm even when damp and stays odour-free for a long time, which you'll appreciate on a multi-day trail; synthetics dry faster and handle frequent washing better. Choose the weight according to the season and the intensity of movement: thin for summer and sports, thicker for static winter activities. Flatlock seams won't rub under backpack straps. Cotton is not suitable here, as it soaks up moisture and then makes you cold exactly where it shouldn't.

Expert advice
Our gear specialists are here for you. We offer tailored advice for any adventure.
Contact an expertFAQs
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.
