1. The secret to staying cold 　Keeps ice for up to 2 days 　It has been confirmed that it can hold ice for 48 hours in a rigorous test environment that alternates between "32°C" and "19°C". 　This high cooling retention capacity makes it ideal for outdoor activities such as camping and fishing, as well as "emergencies" such as power outages and disasters. 　It will be a very reassuring ally as a preparation. 　Even in an emergency, it is possible to store the minimum necessary beverages and food cold. 　*The cold storage period varies depending on the environment in which it is used, such as the ambient temperature, the amount of contents, and the frequency of opening and closing the lid. Proprietary material "DEEP FREEZE™" 　It is a high-performance insulation material with five layers, including a material that repels heat and a special sponge that does not allow heat to pass through. 　It shuts out the hot air outside and locks in the cold air inside. 2. Innovative storage style 　Can be rolled up into a small size and stored 　It is a type that is used by inflating it with air, so when you are done using it, you can remove the air and roll it up compactly. 　You don't have to worry about storage space, and it's perfect for stockpiling with a disaster prevention set. 3. Cleanliness and Waterproofing 　Removable liner 　The inside uses a "waterproof liner" that does not leak water even if ice is directly inserted. 　It can be removed and washed, so you can always use it cleanly. YKK zipper 　Uses YKK's globally trusted "water-stop zipper (zipper that does not allow water to pass through)". 　It prevents rain and water from entering from the outside, as well as preventing the cold air from escaping. 4. Reduced Carrying Burden 　BACKSAVER® Shoulder Strap 　Designed based on ergonomics (how the body works), this strap reduces stress on the muscles. 　It reduces the burden of carrying heavy loads and makes carrying smoother.
