The OTC 0308 neoprene knee stabilizer features spiral stays. Excellent support with moderate medial-lateral stability; buttress pad surrounds the kneecap for added support and stability; upper and lower hook and look encircling straps are adjustable and removable. Designed to retain natural body heat to help soothe aching muscles and maintain flexibility, provides firm, uniform compression to support weakened joints, and offers moderate protection from bumps and bruises. The high-tech, perforated neoprene material breathes, allowing perspiration and moisture to escape for extended wearing comfort. For precisely targeted pressure over soft tissues, any combination of buttress quarter sections can be removed by using scissors to cut through the slits on the interior pocket. The patella (kneecap) opening helps support maintain its correct position at all times.
