Keep comfortable in any weather with merino wool base layers for women. Our women’s base layers are praised for being warm, soft, breathable, and odor resistant. Merino wool absorbs and releases vapor, so you won’t overheat, and they have tiny air pockets that trap body heat for insulation, without the bulk. Shop our full collection of women’s base layers including short sleeve, long sleeve, and leggings. Our women’s base layers keep you warm on their own, but even warmer when worn under a fleece or a jacket for optimal layering. We even have merino wool sports bras to complete the perfect layering system.
