Abstract
A disposable thermal pad includes a substantially planar laminate structure having a first side and a second side and a plurality of heat generating cells embedded between the first and the second sides. The plurality of heat generating cells each are spaced apart and fixedly attached to the laminate structure. The laminate structure provides oxygen permeability to each of the plurality of heat generating cells. Oxygen permeability is achieved entirely on the first side of the laminate structure. The disposable thermal pad is releasably attachable to an inside portion of a user's clothing. The disposable thermal pad is releasably attachable on its first side of the laminate structure so that the second side of the thermal pad may be placed directly against a user's body.
