The Mueller Adjustable Knee Support is comfortable to wear, giving you a full range of motion. The soft neoprene blend retains body heat for soothing warmth while the patented adjustable-tension strap supports your injured or arthritic knee. Antibacterial treatment controls or eliminates odor. The AEGIS Microbe Shield antimicrobial treatment is intended to protect the brace against odor, staining and deterioration caused by bacteria and microorganisms. This treatment does not extend protection to the skin. Its patented tension straps on top and bottom offer controlled compression and a custom fit. The contoured design of the support minimizes bunching behind the knee, while its padded double-layer provides stabilization around the kneecap and patella opening. Fully trimmed edges and smooth seams help prevent skin irritation. This support comes in one size that fits most.
