This is the wrap for elbows and knees that combines targeted hot and cold therapies to relieve pain and promote healing. The contoured, hands-free design straps securely to the affected area, with an integrated stretch sleeve to keep the pad secure on the elbow. Three settings allow the application of soothing moist or dry heat; the removable freezable gel pack provides anti-inflammatory cold therapy. Heat increases blood flow to the source of the pain to accelerate tissue healing, while cold reduces inflammation from acute injuries like strains, sprains, bumps, and bruises. With 2-hour auto shut-off. Compact controller is conveniently tethered to a 9' cord. Machine washable pad. (1 1/2 lbs.)
