| For more than ten years, the Japanese have been using copper supports, which are thought to enhance blood circulation and promote the body's natural healing process. Slip on our knee support, interwoven with copper complex, if you have arthritic knees or general knee pain. Slight electrical charges-so light you don't feel them-work between the support and skin to promote the body's natural healing process. The fiber continues to conduct electricity like copper does as long as you are wearing it. Because the fiber has the ability to store heat, this knee support also raises skin temperature while providing air circulation so you stay comfortable without being overly hot. Machine washable. 62% acrylic/14%cotton/13% polyurethane; 11% acrylic with copper complex. Measure around knee at kneecap. Med (10-13 ) Lrg (13 1/2-16 ) X-Lrg (16 1/2-20 ) |
