CW-X Insulator Performx Tights - Men's If you need something light to wear on your jogs that will keep you warm and not weigh you down, then the CW-X Insulator Performx Tights are right for you! These 80% CoolMax®/20% Lycra® tights use Auto-Sensor® nanotechnology fabric to maintain a constant comfortable surface temperature in a variety of conditions perfect for the cold weather athlete. The PerformX line of tights keep everything in correct alignment for optimum balance, efficiency and power by providing support for the IT band, hip flexors and quads as well as good stabilization of the knees, calves and achilles. The Kinesio Support Web™ acts as a suspension system for the quadriceps, increasing power at the push phase of the running motion. Variable compression facilitates circulation during and after activity, minimizing lactic acid build-up so that you can be active longer and recover faster. The antibacterial fabric freshness is maintained in the garments through titanium and silver fiber technology. Flat seam construction. UV protection with UPF 50+. Imported.
