The compression technology utilized in the Zensah Compression Shooter Sleeve increases the circulation throughout your arm, keeping your muscles fresh and minimizing swelling so that you can focus on shooting with a smooth stroke. Ideal for basketball players as well as any other athletes who need their arm muscles to be warm and energized when called upon. Seamless technology has a second-skin feel, so it won"t get in your way or cause you to overheat. Can also be used in cases where compression would help to treat tennis elbow (tendonitis).
