Igloo Coolers Performance Ice Large Block

With Performance Ice you get extreme, long-lasting cooling power without the watery mess (what we, in the biz, call cooler soup). This modular ice block is next-level, designed thicker to hold more of our supercharged freezing gel with a relatively small surface area, which means it keeps your small-to-large cooler ice-cold way longer and the refreshments inside enjoyably frosty. And, equally as important, you wont end up with waterlogged sandwiches.
