We're so excited to be able to offer this new PowerGrip leg band on our FS Pro line of Shorts, Bib Shorts and Skinsuits. With a fantastic array of features, we're sure you will experience nothing but the ultimate in comfort, durability, and performance. Made from form fitting, Silicone free Lycra fabric with 2-way stretchability. Specially engineered breathable fabric with carbon-texture on the inside of the band guarantees an effective grip on your skin. With a balanced level of compression proportionate to muscle volume, these PowerGrip bands help prevent the legs from riding up and eliminate the sausage effect you can sometimes experience with standard leg grippers. The compression also helps improve blood circulation and body performance. Standard on FS Pro Short, Bibs and Skinsuits.
