[Radweather] Cooling Bag 30L Large Capacity 5 Layer Structure Thermal Bag Cooler Bag Soft Cooler Box Camping Outdoor Bag Popular (30LBlack)

5-layer structure for strong heat and cold retention: The 5-layer structure of 600D polyester + non-woven fabric + 5mm thick polyethylene foam + non-woven fabric + PEVA blocks out cold and warm air, so cold items stay cold and hot items stay warm for a long time. The performance was tested by an external institution and its high cold and heat retention performance was proven. Thermal and cold retention performance tests were conducted at the Japan Textile Products Quality Technology Center (General Incorporated Foundation). We will compare and examine how the temperature changes over time in a PET bottle placed in this cold/thermal bag and in an intact PET bottle in a high or low temperature environment. As a result, food kept at the appropriate temperature for a longer period of time was found to be approximately 3 times larger when placed in a cooler bag. It's obvious when you look at the graph. Large capacity of 30L can hold a lot! : With a large capacity of 30L, there is still plenty of room even if you hold up to 20 500ml plastic bottles. It's box-shaped so it's easy to pack, and you can put your bento straight into it. It can hold a lot, so it's great not only for outdoor activities, but also for weekend bulk purchases. You can hold 20 500ml plastic bottles standing upright, and there's still plenty of room at the top. Recommended as a gift for sports tournaments. If you use 2L plastic bottles, you can lay them down and hold 9 bottles (3 bottles x 3 tiers). It's box-shaped so it's easy to pack! Comes with a pocket that can hold ice packs: The lid has a mesh pocket that can hold cold packs. By putting it in the lid, the cold air flows from top to bottom and reaches the entire inside of the bag, keeping the inside of the bag at a low temperature for a longer period of time. *Cold insulation material is not included. Folds up compactly when not in use: Unlike hard cooler boxes, the good thing about it is that it folds up compactly. Not only does it take up less space when not in use, but it also allows you to compact your luggage on the way home when you're camping or having a BBQ. When folded, it is only 7cm thick. It's flat, so you don't have to worry about where to store it. Large front pocket included: Large front pocket measuring 28cm x 17cm. It's convenient because you can put small items like cutting boards and seasonings in it when camping or having a BBQ, and your wallet when you go shopping, so you don't have to carry another bag.
