Sugoi’s Piston 140 S/S keeps your body working and recovering at its best. While providing optimal breathability and moisture transfer, Sugoi’s Piston 140 fabric compresses key muscle groups to reduce muscle vibration and stabilize them for less immediate fatigue and reduced chance of injury during activity. Post activity, this compression long sleeve helps pump blood back to the heart, speeding recovery by allowing more efficient circulation to flush cramp-inducing carbon dioxide and lactic acid. And it’s comfy to wear, with raglan sleeves, flat seams and Sugoi’s soft PowerMesh Lite panels to keep you from overheating. Plus, you even get 3M Scotchlite reflective accents for enhanced visibility. Sugoi thought of everything.
