1. A heating pad comprising:
a heat pad including an anterior side and a posterior side, the heat pad comprising:
a first layer on the posterior side of the heat pad;
a second layer having a wire, the wire capable of being selectively heated to increase the temperature of the heat pad;
a third layer comprising a reflective fabric positioned to reflect heat from the second layer towards the first layer, thereby decreasing the amount of heat emitted on the anterior side of the heat pad, the reflective fabric comprising hollow polyester fibers passing through a reflective metallized film;
the third layer being located further towards the anterior side than the first and second layers, the second layer being located in between the first layer and the third layer of the heat pad;
a first air gap between the second layer and the third layer;
a fourth layer comprising a batting fiber layer, the fourth layer being located further towards the anterior side than the third layer;
a second air gap between the third layer and the fourth layer;
a battery being in electronic communication with the wire of the heat pad; and
an engagement mechanism to secure the heating pad to a user; and
wherein the second and third layers are configured to direct heat generated in the second layer toward the posterior side and the first layer is configured to conduct the heat generated in the second layer to an outer surface of the posterior side.
