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. Because of the different positions of the front and rear pouches, the user can reverse the vest on the body to change the location at which heat is applied to the front and rear of the body.
