Abstract: A body warming device (10) for warming a user's feet during sedentary activities and a user's hands during substantially any selected activity. A shell member (26) is provided for covering the selected portion of the user's body to be warmed. A heat source receptacle (14) is provided for receiving and retaining a heat source (16). A closure (18) is provided for selectively closing the heat source receptacle (14) in order to prevent the unselected removal of the heat source (16). Insulation (20) is provided between the shell member (26) and the heat source receptacle (14) for regulating the temperature within the shell member (26). The insulation (20) is non-migratory to maintain an even distribution. A lining member (22) may be incorporated to cover the insulation (20). An edging member (24) may be provided for protecting the edges of the panel members (28), the lining (22), and the insulation (20). A heat source (16) is provided for generating heat within the shell member (26).
