Sugoi's Piston 200 Tights are high-tech and super comfortable with a progressive support design that targets specific areas to increase blood flow and speed recovery. While providing optimal breathability and moisture transfer, Sugoi’s Piston 200 fabric takes key muscle groups, isolates and fully encapsulates them to reduce muscle vibration and stabilize them for less immediate fatigue and reduced chance of injury during activity. Their articulated cut, flat-lock seams and elastic drawstring waist ensure a comfortable fit. Plus, you get an inside key pocket and 3M Scotchlite reflective accents for enhanced visibility, too. Sugoi thought of everything.
