The idea of a cooler is simple enough–start with a container large enough for your perishables, add insulation, refrigeration, and quality seals, then you’re off to the races. Whether you’re talking about the best hard shell coolers, soft shell coolers, or just the coolers that will keep your beer coldest, there are a lot of options for your next camping trip. If you’re not already invested in an alternative, you need to check out these QOOL Box Coolers. Designed, engineered and made in Germany, these coolers take everything to the next level with outstanding thermal insulation performance based on vacuum insulation technology installed on all sides, the lid and the base. When you pair that impeccable construction with their so-called Phase Change Material temperature elements, you can get your cooler from ranges of -25°C to +25°C depending on the temperature range you need for your food. In other words, it gets as hot or as frigid as you want it to be. The QOOL Box Cooler is available in both medium and large sizes with either four or 6 temperature elements depending on how much beer, meat, produce and water you want to keep cold at any given time.
