1. The secret to staying cold 　Deep Freeze™ High-Performance Insulation 　This is a material that acts like a "thermos". It has the function of repelling heat from the outside, and can last up to 3 days 　It provides strong cold retention power enough to hold ice. Of course, outdoor activities such as camping and fishing, 　It has a very reassuring cooling retention power as a preparation for "emergencies" such as power outages and disasters. 　*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. ColdBlock™ Base 　The bottom part has a three-layer structure. The heat from the ground is surprisingly strong, but this "three-layer wall" sends heat from below. 　It blocks firmly. 2. Commitment to ease of use 　"Flip open" zipperless ™ lid 　There is no zipper (zipper), and the lid can be opened with one hand. You can take it out immediately when you want to drink it, so 　The advantage is that it is difficult for cold air to escape. It also has an insulated front pocket. HardBody® Liner 　The inside is a hard and durable bucket-like container (liner). Even if you add plenty of drinks 　It does not lose its shape and protects the contents well. 　The entire liner can be removed, so even if it gets dirty, it can be washed completely and is very easy to clean. 3. Ideas for "partitions" to protect the contents 　SmartShelf™ 　There is a removable "special divider" inside. Bottom row: Cold drinks (heavy ones) 　Top row: Sandwiches and fruits (soft) 　In this way, the top and bottom can be stored separately, so you don't have to worry about the weight of the drink crushing soft food. 　When you need a lot of space, you can remove this partition and use it spaciously. 4. Carrying and Care 　Lightweight design for easy portability　 Backsaver® Shoulder Strap 　Straps with non-slip padding, designed to distribute weight.　 　The weight of the luggage is designed to be in the center, so it lightens the burden on the shoulders. Water-repellent and antifouling exterior 　The outer fabric is durable, stain-resistant, and repels water. 　Even if mud or drinks get on it outdoors, you can keep it clean just by wiping it off quickly.
