This Sunbeam Heated Back Wrap delivers soothing heat therapy for common muscle pain in the back. The 23 x 15-inch luxurious Micromink wrap contours to the shape of the back to help accelerate tissue healing and relax sore muscles associated with muscle tension and stress. The back wrap stays in place with an adjustable waist strap that securely fits up to an 85-inch waist for hands-free, targeted pain relief. Customize treatment with 4 heat settings and 2-hour auto-shutoff. Enjoy convenient features such as an easy-to-use push-button controller with LED heat setting lights for visibility in the dark, and a long 9-foot cord. For optional moist heat therapy, spray fabric with water for deep, penetrating pain relief. The entire flexible, Micromink hot pad is fully machine washable for easy care—just disconnect the controller.
