The Boxcooler Backpack By Sebastian Bertram
If you love the outdoors and having picnics but hate warm, soggy sandwiches this Boxcooler backpack fridge is the solution. Turning the traditional cooler design on its head the backpack, designed by Sebastian Bertram, features Thermoelectric Peltier elements instead of the traditional freezer batteries.
The backpack also comes with pockets for picnic essentials such as knives, forks, spoons and a foldable cup. You can either carry it like a normal backpack or fix it to the back of the headrests in your car.
