Colder, Faster, Longer
Cooler Shock Premium Ice Packs (Medium)
An ice alternative that far outperforms ice, Cooler Shock reusable ice packs are designed to provide extended cooling at 18 degrees F that can last up to 48 hours.
Great for camping, picnics, boating, fishing, tailgating, and any perishable transport (both personal and commercial), Cooler Shock ice packs turn warm drinks ice cold in the cooler and your sandwiches won't turn soggy from melting ice. Just return Cooler Shock to your freezer and they'll be ready for the next outing.
DIY Reusable Bags — Just Add Water Once
Cooler Shock ice packs are shipped dry with a proprietary cooling gel mixture inside that turns into a solid block when frozen. Just add water at home, shake, and seal to create reusable ice packs that can be used over and over.
Choose from two closure types:
- Screw cap (with cork and included funnel for filling).
- Zipper version that's sealed permanently shut with an iron.
Thin, Durable Construction
Cooler Shock's flexible, multi-layer bags are made with aluminum and polyethylene to keep the contents secure and reinforced with thin nylon to help strengthen the pack.
Measuring about one-fifth the thickness of rigid ice packs, Cooler Shock's thin walls (8 mils, or about 0.2 mm) both freeze more quickly and transfer chill in a cooler more effectively.
