The Men's CW-X Insulator Tights are the perfect compression tights for cold-weather activity. These pants are made with WarmStretch temperature-regulation fabric to keep a constant comfortable surface temperature. The patented CW-X Support Web supports the lower abdominal section, hips and back to direct power through your core section and supports lower leg muscles and and ligaments for support and vibration reduction for increased efficiency. The Stabilyx Insulator tights help promote circulation both during and after exercise to minimize lactic acid buildup. That means better endurance and shortened recovery times.
