It's NICE when you don't need ICE!
Polar Bear PCM's (Phase Change Material) High Performance industrial ice packs keep you chillin' and keep the ice from spillin'! This heavy duty reusable ice pack is colder that ice and in many cases last longer when housed in the superior insulated Polar Bear Cooler. You don't have to have a melt down ever time you need to break out your Polar Bear Cooler, just place the PBC ice packs around the contents in your cooler and chill out! We recommend 2 for 12-Pack Coolers, 4 for 24-Pack Coolers and Backpack Coolers - and 8 for the 48-Pack Polar Bear Coolers. Once you feel the chill and convenience of use from our iceless ice packs, you'll never go back! Some things are just better simplified! Polar Bear Coolers - you're only as good as your gear!
