Keep ice for EVEN longer


Impressive thermal properties make WILD Cooler boxes the alpha in the pack, industry-wise, with its 50mm thick walls and a 75mm thick lid, freezer-quality sealing properties and one-piece construction. Still, there are a few things you can do to stretch the lifespan of your ice even further – read on.

No air in there
Air is the enemy, when it comes to ice retention. Always try and have your cooler box as full of supplies and ice as you can, then pack and fill in any empty space left with towels or similar.

Cool your cooler
Preload your WILD Cooler box, a few hours before packing it for your trip, with a bag of ice just to chill it. This will mean your ice for the trip will start off in a cold cooler box and stay cooler for longer.

The colder the better
The colder your ice is to start with, the longer it will last. Super-cold ice, ice below zero degrees, is quite dry. Don’t pack your cooler box with ice that is wet or dripping already.

Block and cube
The best mix of ice to pack into your cooler box is a 50/50 mix of large block ice, which melts slowly, and a bunch of smaller ice cubes, which will chill your box’s contents the fastest (and fill gaps between the big blocks).

Don’t lose the water
Don’t drain out water once the ice begins to melt – the ice water will be almost as cold as the remaining ice and will slow its melting. Do, however, make sure any food items in the box are sealed against water ingress.

Throw some shade
Obviously, you want to keep your cooler well out of the sun. You can also throw a wet towel or two over it to help repel the heat.

Keep it shut
Try not to open your cooler box unless you absolutely have to, because every time you let warm air in, the ice has to cool it and starts melting faster.

It’s dry but you can use it
For best results, you can use dry ice in your WILD Cooler box. Just be sure to wrap each block of dry ice in sheets of newspaper before packing. It’s best packed on top of your supplies, rather than under them. Make sure to minimise any air pockets in the cooler box and, whenever you open, let the fumes out before sticking your head in there. Those fumes are toxic. Avoid any contact with your skin, nose, eyes, mouth or clothing, to be sure.
