MUELLER-exclusive HYDRACINN™ fabric is the moisture-wicking catalyst for maintaining superior support with heat management. Base sleeve is made of antimicrobial fabric that is uniquely breathable, extremely soft to the touch with flatlock seams, and features a conforming hourglass design. Inner grip strips complete the anti-sweat/non-slip design to help prevent brace migration and preserve high-performance support. This comfortable brace provides support for stiff, weak or unstable knees, as well as protection after injury.
