A Butterfly Strapping System is both lightweight and incredibly supportive. Pressure is distributed through the torso, then gradually over the upper back. The Granfondo base fabric in the leg achieves greater quadricep compression, with a low profile cuff. Welded Seams and the New Elastic Interface Black Sheep Pad are included. Race fit, crafted for performance. Expect a tight fit to ensure aerodynamics on the bike, or at the coffee shop!
