Its manufacture with an elastic microfiber fabric, polyurethane foam and cotton terry ensures a better fit by providing more elasticity and rapid dispersion of sweat. Its design allows immobilization of the knee in different degrees of flexion-extension (0-5-30-45-60-90) thanks to its femoral and tibial straps for better fit, with silicone dots for comfort. It is indicated for post-surgical knee treatments, rehabilitation and pathologies in which it is necessary to control the degree of flexion. This size 3 knee brace fits a perimeter between 44 and 49 centimeters and has a length of 45 centimeters.
