Non-Hazardous 100% Made in the USA - 5 lbs. when filled, replaces 7 lbs. of ice. Cooler Shock hard gel pack outperforms ice and other gel packs. Why? They stay at 18° Degrees F. for hours on end using a phase change process. Check the others, not even close. Our packs release the largest amount of energy at freezer temperatures to get your food and beverages cold quickly. Put them in the freezer for 24-48 hours (depending on if it's completely warm) and you will have portable cooling power that accelerates cooling. CoolerShock is shipped to you with a dry formula inside. Simply add water and put the screw cap on. The pack turns to gel in 15 minutes. It lasts all day (24 hours) in size-matched coolers listed on our website. Great for fishing, boating, parties, and tailgating. Add room temperature drinks to your cooler and drink them at near-freezing temperatures a few hours later. Drinks should not be left in direct contact with ice packs for a prolonged period as they can freeze. Enjoy our 1-year guarantee - If you have any issues at all, contact us directly for free replacements. We are easy to find, and we are very responsive. Details are on our website at CoolerShock.com.
