KJUS Ski Apparel utilizes innovative design and materials to make their ski jackets and pants waterproof, insulated and breathable. Kjus was launched in 2000 by the Olympic Champion Skier, Lasse Kjus. The KJUS focus was to develop ski apparel that provided comfort and allowed unrestricted movement using the best materials and technologies available. KJUS uses DERMIZAX and Primaloft insulation both of which offers the best water resistant fibers. Buckmans.com is proud to carry KJUS Performance Apparel.
