Durable, ergonomic strap handle made of brown natural leather. Removable lid. The Polarbox coolers in a stylish retro look function like a conventional cooler: just add ice cubes or a frozen ice pack, pack your provisions, and you're ready to go. Whether by the water or in the greenery, the Polarbox, available in various colors, is a real eye-catcher. A double coating of polypropylene (PP) and incorporated polystyrene (AIRPOP) ensure maximum insulation.
