Long-lasting and comfortable, the Proflex 500 Tennis Elbow Support is designed to provide a wide base of support, transferring pressure from the point of muscle attachment to the larger mass of the forearm. It supports both rigorous and natural arm movements. Held in place by a strap with a hook-and-loop fastener that adjusts easily inside a rubberized loop, the Proflex 500 guarantees a custom fit every time. Made of durable, nylon-laminated neoprene, the Proflex 500 Tennis Elbow Support can be worn next to the skin or over clothing.
