The Copper Knee Sleeve utilizes copper ion, nylon, and polyester blend with 3D weave technology to create compression. Copper claims their sleeve and the copper ion fibers relieve swelling and muscle soreness. Unfortunately, there is a latex anti-slip strip included to prevent the sleeve from rolling down. So if you have a latex allergy, this is not the product for you.
Customer reviews have found this sleeve to be supportive for everyday wear around the house and wearing on the job. Some customers had trouble with the knee sleeve rolling down, especially at sizes large and above. If you are not satisfied with the product, Copper has a 100% after-sales guarantee.
