The Petromax cooler bag is an essential part of your gear for being outdoors for 4 or even 6 days without relying on batteries or electricity. The cooler bag keeps food and drinks fresh for days and, thanks to its practical colors, is perfect for catering during hunting trips, boat tours, camping, fishing, and adventurous picnics. With the help of the water-repellent nylon fabric and the waterproof zipper, ice cubes and cooling packs are securely stored in the cooler bag, reliably keeping meat, vegetables, and drinks cool. The shoulder strap and carrying handles make it easy to take the bag anywhere. You can securely attach the Petromax cooler bag to a boat or bike rack using the eyelets for carabiners and similar items. The four separate pockets provide space for small equipment, such as a tripod ring, kindling, or lighter. Thanks to the bottle opener, you can open crown caps directly on the bag. The 8-liter cooler bag can hold up to 4 kg of ice cubes, while the 22-liter cooler bag can accommodate up to 10 kg of ice cubes. It can fit 6 x 0.5-liter bottles or 4 x 1.5-liter bottles. The outstanding feature of these cooler bags is their cooling duration: adventurers can stay in nature for 4 or 6 days and prepare a complete adventure menu outdoors.
