Muji's "Cooler Bag S" is just right! Let's go outside with rice balls and drinks
On days when a large cooler bag feels a bit excessive, Muji's "Cooler Bag S" might be just right. I tried using it in situations where I wanted something compact and easy to use, like eating rice balls on a bench or bringing light snacks to the park.
The reason I chose the small cooler bag is that it makes my belongings compact.

I was drawn to the size of MUJI's small cooler bag because it fits right into the bag I use daily. Until now, I have sometimes carried rice balls and drinks bought from convenience stores in a drawstring bag, but since it has no cooling effect, I felt a bit uneasy during the summer.

A large cooler bag can be bulky and is not suitable for casual use. Therefore, I thought that if the size is just right for carrying cold drinks and rice balls, it wouldn't feel like I'm adding to my load, making it easy to incorporate into my usual outings.
Convenient for a quick lunch during a little walk in the park.

On my way to the station, I stopped by a convenience store, bought some rice balls, and placed them in the bag along with a small ice pack. Sitting down on a bench to eat, I felt that just a light meal turned into a somewhat special moment.
Since I didn't prepare it at home, I can move around lightly, and it's reassuring that I can carry it after buying it in a chilled state.

Also, when I went to the park on a holiday, I tried bringing a little rice ball and some side dishes. Just that alone made the time spent outdoors feel naturally richer.
The advantage of this bag lies in its ability to enjoy without much preparation, seamlessly extending into daily life.

It's just right for drives and watching sports

The compactness is useful during busy weekends. It can hold exactly two 350ml cans, and if you keep it in the car, you can easily grab a cold drink. When watching sports, you can bring beverages and light snacks without any hassle (*), so you don’t have to worry about increasing your load. Its small size is actually very practical, making time spent outdoors comfortable.

The comfort of carrying only what you need

This cooler bag is not particularly eye-catching. However, when I took it out for everyday outings like park walks or drives, I found its size and convenience to be quite pleasant.
There’s no need to carry a large bag; you can easily take only what you need. That simplicity made my time outdoors much more enjoyable.
