Patent ID: 8425578

Claim:
A warming product comprising: a thermal composite that includes a first fibrous layer positioned adjacent to and in contact with a second fibrous layer, a permeability of the first fibrous layer being greater than a permeability of the second fibrous layer, the warming product product further comprising an exothermic composition distributed through the first fibrous layer and the second fibrous layer of the composite, the exothermic composition comprising a metal configured to undergo an exothermic reaction upon exposure to oxygen and moisture, the exothermic composition further comprising a carbon component and metal halide; a moisture-holding layer positioned adjacent to the second fibrous layer and adjacent an exterior of the thermal composite of the thermal composite, the moisture-holding layer containing an absorbent web that includes cellulosic fibers, wherein at least a portion of the exothermic composition is in contact with the moisture-holding layer and adheres the thermal composite thereto; and an aqueous solution contained within the moisture-holding layer that is capable of supplying moisture to the exothermic composition.
