A simple but effective training tool to add to your gym bag necessities. Evolution’s Performance Cuff provides support and compression to those nagging injuries, arm or leg, that you are determined to train through. The Performance Cuff 3” version comes in lengths 8” through 20” allowing you to choose the perfect fit for you. We recommend measuring the circumference of the intended body part and then going down one to three sizes, depending on the amount of compression and support you desire. Performance Cuffs are sold as an individual unit.
