The Stabilyx tights provide optimum targeted support to the core and knees. They're ideal for activities with lateral motion such as skiing and snowboarding and for athletes seeking our best form of knee support. The patented CW-X Support Web™ bands together the muscles and ligaments of the lower leg to stabilize the knee and reduce vibration for increased efficiency. The CW-X Support Web™ also harnesses the midsection, supporting the lower abdominals, hips and back to channel power through the core. Variable compression facilitates circulation during and after activity, minimizing lactic acid build-up so that you can be active longer and recover faster.
