The icebreaker Men's 260 Tech Leggings are the ideal mid-weight base layer for skiing, winter hiking, or cold-weather layering. They are made with 100% Merino wool, meaning not only that they feel soft against the skin, but that they are also naturally odour-resisting & temperature-regulating, perfect for minimal packing. Slim fitting, with flatlock seams to prevent chafing & a gusseted crotch for mobility, they layer effortlessly under other trousers without being restrictive.
