Womens CW-X Insulator Stabilyx 3/4 Capri Tights - Women's CW-X® Insulator Stabilyx™ 3/4 Tights :: Insulator Stabilyx™ Tights use WarmStretch™ temperature-regulation fabric to maintain a constant comfortable surface temperature in a variety of conditions -- perfect for the cold weather athlete. Our patented CW-X® Support Web™ bands together the muscles and ligaments of the 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.
