Iris Ohyama HUGEL Aerogel Soft Cooler 25L Charcoal Aerogel Cooler Super Cooling Days of Foldable Box, (AGSC-25C), Gray, Bag, (5.1 Cooling),

This soft cooler box is made with aerogel, a highly insulating material also used in space suits. It prevents cold air from escaping, providing cooling power comparable to that of hard coolers. Maximum cooling time: Approximately 5.1 days*. (*The time it takes for the bottom temperature to reach 8°C when filled with ice equivalent to 40% of the cooler's capacity. Ambient temperature: 30°C → 9 hours, 20°C → 15 hours, repeated cycles.) [Thermal insulation material "aerogel"] A lightweight solid also known as "frozen smoke." It is porous and has extremely high insulating properties, and is used in space suits that operate in harsh environments of -270°C. [Multi-layer insulation and two-layer structure] [Inner: PEVA sheet (waterproof) / 8-layer aerogel (insulation) / polyester canvas (water-repellent)] [Outer: EPE 15mm (insulation) / aluminum-coated PET film + EPE (heat-shielding) / polyester canvas (water-repellent)] The double structure of the inner and outer layers makes it difficult for cold air to leak out. [Includes a pocket for ice packs] By inserting an ice pack, you can keep your food cool for even longer, even in hot outdoor environments. (Ice packs are not included.) [Foldable] It folds compactly for easy portability and storage. [Easy to clean] The back is made of water-resistant PVC material, making it easy to wipe off dirt. [Convenient in emergencies] It can also be used for temporary storage when the refrigerator is unavailable. The soft type makes it easy to carry and is useful in evacuation sites.
