Coleman 70QT Xtreme 66L Blue cool box

70QT Xtreme Cooler, 66L, 5.5kg <b>Thick, Premium PU Insulation</b>
Tests show that cooling loss is 30% through the top and 30% through the base.

New models feature increased insulation in the lid and base, and reduced insulation onthe sides, resulting in smaller exterior dimensions yet retaining interior capacity and performance.

We uses polyurethane, the highest quality insulation material available on the market - utilizing up to 30% more insulation.

<b>Increased Efficiency</b>
When a cooler comes in contact with a hot floor, heat is transferred directly to the cooler. If the cooler is lifted off of the ground, the heat is transferred through the air in the gap (air is a great insulator). Cooler have two integrated, rounded feet providing the perfect amount of space for air to flow.

Research indicates that the most performance efficient shape for a cooler is spherical, as this is not practical we have angled the corners of selected models to further enhance performance.
