Abstract: A garment applies heat to the neck, head or torso with air-activated chemical heating packets. The garment is formed from cloth and is preferably soft and sufficiently supple to conform to the body contours during use. The garment has at least one pouch positioned between two layers of cloth for holding the air-activated heat-producing packet. A layer of cloth between the heating packet and the body is a high pile cloth with air-trapping qualities for diffusing heat supplied by the heating packet to distribute the heat evenly to the body for assuring comfort for the user. In one form of the invention, the garment comprises a neck wrap, scarf, bandanna, a head covering in the form of a hat liner, or a cap insert. The neck wrap, scarf or bandanna includes an elongated pouch for holding the heating packet and has overlapping ends that can be fastened together by means of hook-and-loop fasteners.

Abstract: A reversible vest is provided for heating the body core by applying heat to the torso by means of an air-activated chemical heating packet. The vest is formed from cloth and is preferably soft and sufficiently supple to conform to the body contours during use. The vest includes two layers of cloth lying adjacent to one another. A pouch is provided between these layers of cloth for holding the air-activated heat-producing packet. The layer of cloth between the hot chemical packet and the body is a high pile cloth with air-trapping qualities for diffusing heat supplied by heating packets to distribute the heat evenly to the body to assure comfort to the user. The reversible vest has front and rear panels with pouches in different positions. The pouches are in heat-conductive relationship with the body for transferring heat from the chemical heating packet to the body core.
