Mizuno Volleyball Arm Sleeves Pair in Navy. Used by the U.S. national teams in International competition. Great for warmth, moisture management, and to help decrease the sting of the impact of the ball and ground (for example, when passing a ball or playing defense in volleyball). Extends from bicep to forearm. Mizuno Runbird logo. One size. Signs of wear, but in very good used condition. Pictures make it appear with more wear than the actual arm sleeves. Smoke free home.
