Let it snow: KJUS FAST Thermo Core™ and our specially developed Black Magic fabric keep your legs warm when temperatures drop, and prevent chills after intensive exercise by balancing body climate. And the Schoeller Dynatec fabric in the lower parts – which is resistant to tears and abrasions – acts as a shield against tears and injuries caused by ski edges. The high-tech membrane is 100% waterproof, highly breathable and extremely stretchable, providing comfort and ease of movement.
