The 3M™ elbow support provides mild compression that supports weak, injured or stiff elbows. A stretchy material fits snugly in place and moves with the body while you remain active. The stitched neoprene panel retains heat, improving blood circulation. This extra-large elbow support is also breathable to let sweat evaporate and keep skin dry. Reinforced edges prevent the Ace™ compression elbow support from slipping out of place. It fits onto either the left or right elbow for convenient versatility.
