Abstract: A body heating device which utilizes heat from one's own breath to warm various designated body parts during a cold outdoor activity. The device comprises a central conduit having a mouth opening, said central conduit connected to a network of tubes, and an attachment means for attaching said tubes and conduit to a person's body. The body heating device preferably includes a distribution control assembly connected between said central conduit and said network of tubes, for allowing the person to select the amount of heated air to be delivered to different body parts. The body heating device is worn on the person's body, and each of the open ends of the tubes are placed near those areas of the body to which hot air is to be delivered. By blowing air into the mouth opening end of said central conduit, a pocket of hot air travels to the open ends of the tubes, thereby delivering hot air to the selected body parts.
