This soothing back warmer is made from a blend of genuine angora, which warms the skin to boost circulation and ease arthritis and back pain. Exclusively from Hammacher Schlemmer, the silky, fluffy hair of angora rabbits is eight times warmer than sheep's wool yet lightweight and breathable, providing a comfortable layer of insulation that can be worn all day. Without the bulk of standard back braces, it covers the torso from the diaphragm to the hips and ensures skin maintains a constant temperature, stimulating blood flow and preventing the stiffness that can occur when muscles become cold. The cozy garment pulls over the head and has a seamless design that will not show through clothing or irritate the skin with scratchy zippers or fasteners. 44% angora blended with 41% nylon/11% wool/4% spandex for durability and a comfort fit. Hand wash. White. Unisex sizes L (52"-54"), and XL (56"-58"). 15 1/4" H X 10 1/4" W. (1 oz.)
