Get the Support You Need to Succeed! Copper Joe products have the highest copper content GUARANTEED! Rather than spraying fabrics with copper, we infuse it directly into the nylon fibers. Our products are constructed with 85% copper-infused nylon with the HIGHEST genuine copper quality ions (Cu+ and Cu++) rather than copper oxide (Cu2O). While having the highest copper content and BEST quality copper ions, Copper Joe products will give you the support you need whether recovering after or during any activity and are also designed to support athletes, weekend warriors or anyone with an active lifestyle seeking relief. Copper Joe products are designed to provide enhanced protection and give you a superior experience while helping to reduce muscle soreness and pain.
