This is the heated wrap designed to simultaneously soothe sore muscles in the neck and shoulders. Unlike typical rectangular heating pads that do not provide ideal coverage or contact, this wrap features slightly weighted edges and a magnetic closure that provide a custom fit around the upper body. The integrated heating element delivers even, deep-penetrating heat that stimulates blood circulation to loosen muscles, helps relieve swelling, and soothes joints. The tethered controller adjusts the temperature to four different levels and the 100% polyester flannel wrap is soft against skin. With 30-,60-, and 90-minute timed shut-off. Machine washable. AC plug with 9' cord. 24" L x 33" W x 3/4" D. Not for use with pacemakers.
