The Swede-O® Elastic Knee Tetra-Stretch is designed with a seamless, 4-way stretch material to help prevent fabric from slipping, bunching, or rolling during sports or activities. Its light support is ideal for mild injuries, aching and/or weakened knees. Gentle compression helps reduce inflammation. The seamless, ventilated material contours to the natural shape of the knee for comfort during active use. Discreet under clothing; bilateral design fits right or left knee.
