Cordless Lower Back Heat Therapy Wrap by Sharper Image

The Cordless Lower Back Heat Therapy Wrap by Sharper Image uses Far Infrared Ray (F.I.R.) heat to melt away chronic pain. The infrared heat penetrates bone and muscle tissue, but doesn’t get hot to the touch, making it ideal for those with sensitive skin. Features 4 adjustable heat settings and soft, stretchable fleece material. Available in sizes S/M (waists up to 40″) and L/XL (waists 40″-50″).
