The OS1st AS6 Performance Arm Sleeves provide relief from elbow pain from arthritis, bursitis, and other conditions using support and graduated, medical-grade compression. OS1st's Compression Zone Technology applies varying levels of pressure to six 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 AS6 Performance Arm Sleeves can also be comfortably worn under clothing. During workouts, moisture-wicking fabric helps keep the sleeves on securely, preventing chafing and making sure they stay in place no matter what you're doing! Reflective logos on each sleeve also give night runners a little extra visibility on the streets. Each package includes two compression sleeves.
