PERFORMANCE ICE KEEPS ITS COOL

It’s just an ice block, right? No way, frostier cooler seekers! The thermodynamics behind Performance Ice are complex, but its function inside your cooler is simple: Maintaining a lower temperature for much longer. We designed Performance Ice thicker to hold more of our supercharged freezing gel but with a relatively small surface area — that means these ice substitutes lengthen the time of heat absorption and decrease the speed of heat transfer which means Performance Ice helps significantly extend how long your cooler stays ice-cold and the refreshments inside enjoyably frosty.
