The Women's 200 Oasis Tights from Icebreaker are a go-to lightweight baselayer bottom. The 200 Oasis Leggings provide the natural benefits of merino wool in a highly versatile, highly comfortable design. The original 100% merino wool jersey insulates during frigid days on the trail or the ski hill, and it resists odours and breathes efficiently on runs, hikes and summer trips into the mountains. The updated design features a gusseted construction for unrestricted movement, and a brushed elastic waistband and flatlock seams for chafe-free comfort. Womens 200 Oasis Thermal Leggings
