Cooler Shock Reusable Ice Packs for Cooler 14x10 (3-Pack) — 18°F Phase-Change, Up to 48-Hour Cold Retention

Cooler Shock Reusable Ice Packs are refillable, nylon-reinforced freezer packs sized 14" x 10" that deliver up to 48 hours of cold without messy melting ice.

Take the guesswork out of keeping food and drinks cold on trips, at the beach, or during outdoor events. These Cooler Shock packs use an 18°F phase-change formula to hold safe temperatures longer than plain frozen water. Each pack is built to be refilled with water, frozen, and reused indefinitely, freeing you from buying or lugging bulky loose ice and giving you more usable cooler space.

How long will these ice packs keep my cooler cold?

Under typical use in a size-appropriate insulated cooler, each pack helps maintain safe cold temperatures for up to 48 hours. Performance varies with cooler insulation, ambient temperature, and how often the cooler is opened.

• 18°F phase-change formula for extended cold retention
• Designed to maintain safe temps up to 48 hours in matched coolers
• Works best when paired with a properly sized cooler and minimal door openings

How do you prepare and reuse a Cooler Shock pack?

Preparation is simple: fill the pack with water using the included funnel, shake to distribute the fluid, securely tighten the cap, and freeze flat. After use, refill and refreeze—no disposal or special recycling required.

• Fill once with tap water, using the funnel for quick, clean filling
• Nylon-reinforced exterior resists punctures and repeated handling
• Cap and seal design prevents leaks during transport

Will these replace loose ice and save space in my cooler?

Yes: each 14" x 10" x 1.5" pack displaces roughly 5–6 pounds of loose ice, so you reclaim cooler volume for more food, beverages, and gear. A 3-pack allows placement across compartments or layering for even cooling.

• Each pack replaces about 5–6 lbs of ice to free up interior space
• Flat profile stacks neatly against cooler sides or lids
• Three packs provide flexible placement for even temperature coverage

What activities are these packs best suited for?

They’re built for outdoor and travel use—camping, fishing, tailgates, beach days, and road trips—where long-lasting cold and durability matter. Check your cooler's interior dimensions before you buy to ensure a good fit.

• Ideal for coolers, beach totes, lunch boxes, and soft-sided ice chests
• Durable construction stands up to transport and repeated freezing cycles
• 3-pack gives coverage for multi-day trips or multiple cooler compartments

Who is this for? If you regularly pack coolers for outdoor adventures, weekend trips, or event catering and want reliable cold without the bulk and mess of loose ice, Cooler Shock 14" x 10" reusable packs are designed for you. They’re particularly useful for people who need predictable cold retention, want to maximize usable cooler space, or prefer reusable gear that reduces waste. Measure your cooler interior to confirm fit, then use one to three packs depending on trip length and cooler size. Cooler Shock is a practical, reusable alternative to bagged ice for campers, anglers, tailgaters, and families who want longer-lasting cold with minimal fuss.
