The Thermoskin 4 Way Compression Knee Sleeve is an anatomically designed support that combines spandex with advanced hosiery technology to provide protection and support for weak and injured knees without continual bunching. It aids in the reduction of swelling and provides temporary pain relief. This four-way stretch support is designed for women and men, and is suitable for both adults and children. It features innovative 4-way elastic contours that provide even compression to reduce swelling and support for injured muscles and joints, with comfort for extended wear. The sleeve is made from a blend of 45% polyester and 35% rubber, and is designed to be worn on the knee. To use, simply slip the end of the support over your foot and slide it up and over your knee so that the mid-section of the diamond-shaped weave sits directly over the knee patella. Please note that this product contains natural rubber latex, which may cause an allergic reaction. If pain persists, discontinue use and consult your medical professional.
