The OS1st ES3 Performance Elbow Sleeve provides relief from elbow pain from arthritis, tennis elbow, and other conditions using support and graduated, medical-grade compression. OS1st's Compression Zone Technology applies varying levels of pressure to three different zones, giving you just the right amount of compression in each area to promote circulation and hasten recovery while keeping you comfortable resting or during workouts. With a slim profile, the OS1st ES3 Performance Elbow Sleeve can also be comfortably worn under clothing. During workouts, moisture-wicking fabric helps keep the sleeve on securely, preventing chafing and making sure it stays in place no matter what you're doing! Each package includes one compression sleeve.
