It's not your average chip off the old ice block — these ice packs are part of Igloo's legacy MaxCold Ice family featuring their non-toxic Ultratherm gel for extended cooling performance in your ice chests or softside cooler bags. And with this convenient ice substitute bundle, you get four MaxCold Ice Blocks for more versatility: Two small blocks and two medium blocks. Just freeze (and re-freeze as often as you like), then throw them in your cooler. These ice packs help keep your refreshments chilled and, equally as important, you won’t end up with waterlogged food or packaging.
