11. A sleeping bag comprising:
a shell including an inner layer defining an interior space for a user of the sleeping bag, and an outer layer defining an exterior surface of the bag;
a heating pad pocket secured to the shell on the inner layer, the pocket being sized and shaped to receive and retain a heating pad therein;
a battery pocket sized and shaped to receive and retain a battery electrically connected to the heating pad; and
further comprising at least one loop for securing a cord electrically connected to the heating pad to the inner layer of the shell.
12. A sleeping bag as set forth in claim 11 wherein the heating pad pocket has a top portion disposed generally adjacent to a torso of a user in use for positioning the heating pad generally adjacent to the torso of the user, and a bottom portion disposed generally adjacent to feet of a user in use for positioning the heating pad generally adjacent to the feet of the user, the bottom portion including a closable open end generally adjacent to a bottom peripheral edge of the shell.
13. A sleeping bag as set forth in claim 11 wherein the heating pad pocket has an intermediate portion disposed generally between the top portion and the bottom portion for positioning the heating pad generally between the torso and the feet of the user during use.
