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 with a unique brick shape designed thicker to hold more of our supercharged freezing gel with a relatively small surface area, which means it keeps your small-to-medium coolers ice-cold way longer and the refreshments inside enjoyably frosty. And, equally as important, you won’t end up with waterlogged sandwiches.
