Kae Hwa’s ThermoBreathe™, the thermal-focused tier of the FunPack series, is a highly engineered air-permeable laminate designed specifically for exothermic heat packs, medical heating patches, and pocket warmers. By acting as a precise "oxygen valve," ThermoBreathe™ dictates the exact heating profile of the product while providing the extreme mechanical toughness required to safely contain abrasive iron powder during active use.
