Sub bag

I liked that it has a carry handle on top. When the main bag is a backpack, I can carry it by hand, and when the main bag is a handbag, I can use this as a backpack, which is very convenient.

Father's birthday present

I bought this as a birthday present for my father. He is 175cm tall. He said he would use it for commuting to and from work. He was pleased that it could be used not only as a main bag but also as a sub-bag for travel, so it seems useful in various situations.

Bag for son's gym clothes

I'm using it as a handbag with the handle. The size is good, and since it’s lightweight and made of soft material, it’s very convenient.

The color is cute

I liked the calm brown color and purchased it. It's a backpack, but it has an adult vibe to it. It also compacts down, making it easy to carry.

Before the marathon

I wanted something to hold my personal belongings, so I purchased this! I like that the color doesn’t highlight the logo. It looks sturdy, so I’m hoping for good performance in the future.

It can stick due to sweat

The size feels small if you are tall, but considering the weight when filled, it can be said to be adequate. It is said to be water-resistant, but it often sticks when wet with sweat, so I can't say it’s comfortable. However, the condition inside doesn't easily worsen, and since it has a handle, it is indeed user-friendly.

The 13L capacity is just right and convenient for storing a bathing set after descending the mountain. It’s a light and functional drawstring bag that I definitely want to take along for mountain trips.

Usable by both children and adults

The design is sleek; the logo is large, but it's in the same color as the fabric, so it doesn’t stand out too much. It’s a decent size, so it can be used not only for children’s field trips but also for adults’ gym and travel gear.

Having this as a staple in my usual bag is convenient for when I have a lot of things. It might even be good as a bag-in-bag for organizing items within my bag!

Convenient for separating items

I’m using it for organizing inside my duffel bag. It’s convenient to carry everything in one pack, like towels and changes of clothes for the hot springs. I use different colors and stuff sacks to separate contents.

I use it as a gym clothes bag.
The size is just right, and it fits gym clothes, tops and bottoms, and a tracksuit.
It also comes with a hook string, so it's apparently convenient to hang.

Used as a swimming bag

I purchased it as a swimming bag for school. The size is pretty good. It's not inconvenient, but if it were just a little bit bigger, that would have been great. Also, it's inexpensive, so I suppose that's why it is the way it is, but I thought it would have been nice if the fabric were a bit thicker even if the price were a bit higher.

A product with a good idea

I think it's a very convenient and good idea product when I have only a few things like a smartphone or an eco-bag, or when I just want to carry a jacket. I do feel that the logo is a little too big though.

However, I thought the handles could be a bit sturdier, so I gave it a -1.

For club activities

For my daughter to carry her gym uniform. It fits a T-shirt, shorts, and a towel, and there's still some room. I've been using it every day for about six months, and while the logo has slightly worn, it hasn't peeled off. There's no tearing or fraying.
