Each pack includes a funnel for easy filling, a durable cap, and a phase-change formula that targets a ~18°F freeze point so your perishables stay colder longer than plain ice. Sold as a 5-pack, they give you flexible coverage across compartments or multiple outings.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these packs keep things cold longer than regular ice?\u003c\/h3\u003e\n\u003cp\u003eThe Cooler Shock formula is a phase-change gel engineered to maintain a targeted cold temperature as it slowly melts, absorbing heat at a steady rate. Because it’s designed to linger near 18°F while melting, it reduces temperature spikes that commonly occur with ordinary ice.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePhase-change gel holds a consistent low temperature longer than water ice.\u003c\/li\u003e\n  \u003cli\u003eNylon-reinforced exterior resists punctures and repeated freeze cycles.\u003c\/li\u003e\n  \u003cli\u003eDisplaces free water so cooler contents remain drier and easier to organize.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I prepare and use these freezer packs?\u003c\/h3\u003e\n\u003cp\u003ePreparation is simple: add water through the included funnel, tighten the cap, shake to settle the gel, and place the pack in the freezer flat until fully solid.
