Cold won’t harm you: some parts of the upper back boast a special fabric containing tiny wax balls, which trap excess heat and release it when temperatures drop. Not only will this super-stretchy jacket with its elastic insulation fabric keep you warm, it’s also 100% waterproof and highly breathable, so you stay dry all day long. Super comfortable to wear, this jacket has AC vents for a fast, natural cooling effect, eyewear cleaning bag, detachable hood, and many more features that serious skiers will love.
