A disposable thermal pad comprises 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 has means for providing oxygen permeability to each of the plurality of heat generating cells. The means for providing oxygen permeability is located entirely on the first side of the laminate structure. The disposable thermal pad also comprises means for releasably attaching the thermal pad to an inside portion of a user\s clothing. The means for releasably attaching is also located on the first side of the laminate structure so that the second side of the thermal pad may be placed directly against a user\s body.

A disposable thermal pad comprising: a) a substantially planar laminate structure having a first side and a second side and a plurality of heat generating cells having an oxygen activated heat generating chemistry embedded between said first and said second sides, said plurality of heat generating cells each being spaced apart and fixedly attached to said laminate structure, said plurality of heat generating cells occupying an area less than about 42% of an area defined by said substantially planar laminate structure, so that said heat generating chemistry is minimized while providing an overall heating perception to a user, said laminate structure having means for providing oxygen permeability to each of said plurality of heat generating cells, said means for providing oxygen permeability located entirely on said first side of said laminate structure; and b) means for releasably attaching said thermal pad to an inside portion of a user\s clothing, said means for releasably attaching being located on said first side of said laminate structure so that said second side of said thermal pad may be placed directly against a user\s body.
