Extended period cooling packs are provided by employing reaction mixtures of coated particulate matter and a liquid reactant, where the liquid reactant reacts with the particulate matter in an endothermic reaction. The coating acts to slow the rate of reaction between the reactants, so as to extend the period of cooling.
