LONG LASTING INSTANT HEAT PACK: Instant hot packs are reusable by placing the body warmer heat pack in boiling water, with a rag underneath it, until the warmth pack returns to liquid form. For best possible results, let cool and store in liquid form.
HEAT PATCHES AND WRAPS: Camping heat packs and camping hand warmers can last from 1-2 hours depending on size and insulation. Body warmers go from liquid to solid by emitting heat from the protected, sodium acetate solution once you snap heat or click it hot to turn on.
