A wool base layer knitted in soft merino wool provides good warmth, wicks moisture, and breathes well. It keeps you properly warm in truly chilly temperatures, and in addition, the base layer dries quickly should it get wet. Unlike many other materials, merino wool doesn ’t begin to smell bad even if the garments get sweaty. We offer a wide selection of comfortable wool base layers for women. Choose between base layer tops and bottoms in several different colors and patterns from well-known brands like Kari Traa, Icebreaker, and Woolpower.
