FAQ|Frequently Asked Questions

How long can it keep things cold?
It depends on the usage environment and amount of ice packs, but using ice packs or ice together allows you to carry drinks and food in a properly cold state. The roll-top design and 3-layer structure help retain cold air, making it useful for day camping, picnics, and as a lunch bag for commuting.
Are ice packs necessary?
To achieve better cooling, we recommend using ice packs or ice together. Especially in summer or for long use, adding frozen ice packs can extend cooling time.
Which is recommended, S size or M size?
If mainly for everyday use, the S size is recommended; for camping or leisure with more storage needs, the M size is recommended.

6-pack of 500ml cans, drinks for multiple people, carrying food, family camping
Can it hold a 500ml PET bottle?
Yes. The M size is designed to fit a 6-pack of 500ml cans as is, making it suitable for carrying 500ml PET bottles and beverages.
Is it waterproof?
The outside uses Tyvek® material, which is lightweight and highly durable, but be careful as it can stain when it comes into contact with water.
What is Tyvek material?
Tyvek® is a special material made from high-density polyethylene. It has a unique paper-like texture but combines high durability, light weight, and waterproof properties, so it is used in a wide range of fields such as outdoor gear and building materials.
Can it be folded for storage?
Yes. When not in use, it can be folded small for storage. Unlike hard cooler boxes, it doesn’t take up much storage space, making it convenient for camping or car use. User reviews also mention it is "lightweight and folds compactly."
Can it be washed?
If it gets dirty, wipe it off with a soft cloth or lightly wipe the inside with water. Dry it thoroughly after use to keep it comfortable and durable for longer.
Can it be used outside of camping?
Of course. They are useful in various situations such as lunch bags, shopping cooling bags, parks, beach trips, fireworks festivals, and music festivals. Because they are lightweight and easy to carry, they are also recommended for everyday use.
What is the difference between soft coolers and hard coolers?
Soft coolers are lightweight and easy to carry, and their compactness when stored is a big advantage. However, their use differs from large hard coolers designed for several days of cooling. Many users prefer the convenience of soft coolers for day trips, picnics, and lunch use.
