The Reebok 10K Elbow Pad has special modified EVA foam in the forearm and tricep areas which make it extremely lightweight and form fitting. F.I.T construction conforms the elbow for a custom fit. The F.A.V system provides comfort with superior air circulation. The 10K Elbow Pads feature griptonite on the elbow, forearm and tricep area to lock in the perfect fit and keep pad from sliding down the arm. Reebok Play Dry wicks moisture away from the body and the Direct Sweat Management channels moisture away from the elbow.
