Calf muscles seem to get all the focus from compression gear, but the muscles in your arms can benefit just as much from the improved circulation and support that compression can deliver. 2XU provides you with the opportunity to show your arms some love with the MCS Elite Compression Arm Guards, specifically designed to reduce fatigue and improve recovery time after hard arm workouts. Whether you're cross-training to build upper body strength or doing endless tennis ball drills in the pool for your forearm stroke, the arm guards will add support while remaining breathable and quick-drying. 2XU even constructed them to be left and right-specific, so you can be sure you're getting targeted compression where you need it.
