LOGOS Outdoor Hyper-Ice Point Cool Master Backpack XL Capacity: 35L Carbon I mainly use a silver Hyper-Ice Point Cooler soft cooler box, and I purchased this one for PET bottles, but I'm selling it because I haven't had a chance to use it. This high-performance soft cooler is designed to further enhance the performance of the [Ice Point Pack] series. When used as a set, it exhibits cooling capabilities comparable to hard coolers, making it suitable for storing ice cream and frozen foods. By attaching the included shoulder belt, it can be carried like a backpack. The vertical design improves cooling performance. It features a stylish carbon-look color scheme. Unlike hard coolers, which can be difficult to store, it can be folded compactly when not in use. We recommend the [Ice Point Pack] (sold separately) for ice packs. Of course, general ice packs can also be used, but the [Ice Point Pack] enhances cooling power, allowing ice cream to be stored for up to 11 hours.
