The 200 Oasis Leggings are Icebreaker's ultra-comfortable base layer bottoms that make the perfect foundation for your everyday cold-weather layering. Made with 100% Merino Wool jersey fabric that’s breathable, insulating, and odour-resistant, the Oasis also features a slim fit and gusseted construction for unrestricted freedom of movement. The brushed elastic waistband and flatlock seams also eliminate chafing with a smooth next-to-skin feel. Inspired by nature, Icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino is an annually renewable fibre that naturally resists odours, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
