The Women's Base Trousers No. 3 are comfortable, warm bottoms in a classic style, made from soft Merino wool with smooth terry knitting on the inside. They are perfect as a base layer closest to your skin since they wick away moisture and insulate even when wet. In addition, Merino wool is not scratchy and has natural anti-bacterial properties so it does not need to be washed as often. Flatlock seams prevent chafing.
