The Petromax cooler backpack is the perfect companion for independent cooling on the go and the ideal gear for your next adventure. It keeps your drinks and food cool and fresh using only ice cubes and without any electricity. The cooler backpack is available in two different sizes. The 17-liter version provides 6 days of off-grid cooling, while the 27-liter cooler backpack offers up to 8 days. The comfortable back padding, chest strap, and individually adjustable shoulder straps ensure pleasant carrying wherever your journey takes you. Thanks to the carrying handle and the two side handles, you can always set the cooler backpack down upright and quickly grab an ice-cold drink by simply pulling down the waterproof zipper. The water-repellent nylon fabric combined with dirt-resistant surfaces allows you to transport your provisions safely and prevents melted water from leaking. The practical 6 loops give you the option to attach accessories with a carabiner hook for secure transport. Additionally, you can secure other items using the elastic bands. The large front pocket, two side pockets, and two mesh pockets provide space for fire-starting accessories, such as a fire kit or fire piston. You can also easily carry dishes and camping cutlery in the backpack, making you well-prepared for an evening by the campfire. The cooler backpack is the ideal companion for independent cooling, giving you the freedom to be self-sufficient on the road for several days.
