Women's wool base layers are just what you need to stay active in all kinds of weather. Stock up on women's base layers from tanks and tees to long sleeve shirts and full-length pants in a variety of styles. Whether you need to warm up or cool off, Merino base layers help regulate your core temperature, staying soft and dry next to your skin. Features like flatlock seams that help prevent chafing, as well as the natural breathability of Merino wool, add up to extraordinary comfort.
