The side mesh pocket can hold a water bottle or the included purse pouch.
A 10mm D-ring is attached to the bag, so you can connect it to the spring strap for safety.
A zipper pocket on the back of the main body can hold a pass case, wallet, or other valuables that you want to take out while carrying the bag on your back.
In addition, the back strap has a D-ring, so you can attach an emergency buzzer to it.
It is convenient for attaching an emergency buzzer or hanging your favorite small items.
There is an opening (zipper type) on both sides of the back that leads inside. This is very convenient!
You can take out your stuff with the backpack on your back.

Furthermore, there is a D-ring near the opening, so if you attach a spring strap and a pass case here, you can take them out while carrying the backpack, making it easier to get on the train or bus.
The 10mm D-rings are attached in 6 places, so you can use them in different ways depending on the situation.

A urethane pocket on the back side can hold a 12-inch iPad.
It can also hold an A4 size notebook.
Also has bottle pockets on both sides.
The bag is made of the same material as the interior fabric, with emphasis on the capacity of the main body.
On the back of the bag's cover (lid), there is a mesh pocket with a zipper closure, so you can store things like anti-sickness medicine for field trips, a copy of your insurance card, a GPS device to prevent lost children, a bag of monthly school fees, and more. It is perfect for keeping important things in.

There are two types of looped tapes above the side pockets. The upper tape can be used with a carabiner to attach small items.
The lower tape with reflective belt is an auxiliary tape for the side pocket.
It works as a holding tape when you put a folding umbrella or taller small items.
It also has a D-ring for attaching your favorite items or a name holder for excursions or travel.

A loop with buckle is attached to the top of the bag.
This allows you to secure the backpack through a fence or pole, making it convenient when storing it in a closet. Lightweight clothing and helmets can also be attached, and handbags can be temporarily secured.
There is a loop-shaped flat elastic attached to the end of the length-adjustment belt for the back carrying strap. After adjusting the belt to a length that suits your body, wrap the belt around the belt in a circular motion to turn the flat elastic over.
This is similar to the function employed in baby carriers.
After adjusting the length, the stretched belt should not get caught on a fence or the like, so that it does not lose its balance and fall over.
This feature was adopted to prevent the belt from getting caught when putting the backpack in the front basket of a bicycle and taking it out.

Size L* Advice on storage
The concept is [keep everything you do while moving on your back].
It may be difficult to get used to and confusing at first, but we hope you will experience this ease of use.

[Points of storage that make it easier to use!]
1. Put heavy items on the bottom, back side. Put light items on the top, in the front, to make them stable.
For example, put clothes, lunch boxes, wet tissues, shoes, etc. on the bottom.
2. Put [frequently used items] on your dominant side. Put the items you don't often take out on the other side for easy access.
If you are a mother, put your shopping bag, mother-child notebook, etc. on the dominant hand side.
A folding umbrella of about 27 cm in length can be stored lying on the bottom, with the handle on the dominant side.
In addition, if you store soft items on the dominant hand side, you can have fun with the capacity, so when you buy a medicine bag from the pharmacy or other small items, you can quickly open the bag and put them in the bag.
The back pocket is convenient for a wallet, card case, or smartphone.
The front pocket can be used to store rain jackets or other items that are used infrequently but would be a nice to have.
5. Flat items such as documents should be placed on the back. (An A4 notebook can fit in the back pocket.)
6. 13" laptop in the main body of the backpack.
A 12-inch iPad fits in the internal urethane-filled pocket.
