Zero Ice Reusable Cubes - Large

The heavyweight of the range.

Zero Ice Reusable Large Cubes are big 5cm cubes with more mass in every one, so they freeze solid and give up their cold slowly. They're the backbone that keeps a full cooler going all day.

Lay them in as your base, then fill the gaps around them with standard or mini cubes for cold in every corner and no warm spots. Like the rest of the range, each cube is sealed and filled with purified water in a tough, BPA-free shell. Nothing leaks, nothing melts, and nothing ends up swimming in the bottom.

They hold their cold for up to 48 hours in a closed cooler, then go back in the freezer for next time. Fifty cubes to a bag, good for hundreds of trips.

Freeze it. Pack it. Forget it.
