The Mueller HG80 Knee Brace is a cutting edge knee brace which provides support for stiff, weak or unstable knees, as well as protection after injury. Featuring MUELLER`s exclusive HYDRACINN fabric, the HG80 Knee Brace offers quality support and heat management. Its base sleeve is made up of antimicrobial fabric that is uniquely breathable, extremely soft to the touch, and features a conforming hourglass design. The Mueller HG80 Knee Brace also offers inner grip strips complete with anti-sweat/non-slip design to help prevent brace migration and preserve high-end performance support. With an upper strapping system which locks the brace into position, and an outer mesh with bidirectional stretch fabric which comfortably locks across the quadriceps, the HG80 Knee Brace offers a stable and comfortable protection for your knees. Flexible steel springs support both sides of the knee, yet allow leg flexation and extension. Together with its Tibial Containment System, and formfitting HOURGLASS Design, the Mueller HG80 Knee Brace is by far a must have for today`s aggresive tennis player.
