Need your beer to stay colder, longer? Of course you do, and that's why you'll reach for this incredibly long-lasting ice pack. Once it's reached 28 degrees, this little pack keeps ice frozen up to 50% longer than standard ice packs. That means no more lukewarm drinks or melted ice cubes. The pack lasts a lifetime (literally) and is dishwasher safe, so there's no reason not to toss one in your cooler.
