CW X Men's Full Length Conditioning Tights belong to a new class of high performance equipment known as conditioning wear. This clothing is engineered to provide a host of benefits to your body, including key muscle group support, increased endurance, shorter recovery times after exercise, lactic acid buildup prevention, and precise knee joint alignment. Established in Japan in 1991, CW X based its designs on the human body's unique motion during exercise. Perfect for running, cycling, climbing, and snowsports, Conditioning Tights work by combining two unique zones of stretch material. The body is constructed from a Coolmax and 4 way stretch Lycra blend, providing targeted muscle support and impressive moisture wicking properties. The key to the Conditioning Tights, however, lies in the 2 way stretch Conditioning Web that encircles the knee joint and key muscle groups. While stretching longitudinally, this web holds muscles securely in place laterally, reducing vibration and increasing comfort. Flat seam stitching throughout ensures chafing is never a problem.
