Compresses exterior muscle complex for relief from symptoms of epicondylitis. Simple, effective and easy to apply. Uses a single, preinflated air cell to concentrate compression on the extensor muscle (and not around the arm) for more support and less constriction. Conforms to the arm’s tapered contour, and comfortably cushions sensitive injured muscles. Air cell within elastic band fits either arm of most adults. One size fits most. Available in beige or black.
