It also has general functions such as a valuables pocket, a D-ring for attaching a key holder, and a two-layered main body compartment that is useful in sports and other situations,
It is designed to be used in all kinds of situations.

Removable rain cover
Sudden rain or snow. Even if you can cover your body with an umbrella, your backpack tends to get wet.
In such cases, a rain cover that can be quickly removed is very convenient.
If it is just for a short time, you can leave it on and go on your way.
But if you are walking for 10 or 20 minutes in heavy rain. You will get very wet.
Also, if it is a windy day, for example,
For example, on a windy day. Leave your backpack at the playground.
When you come back, it is white with dust and sand. What a day!
In such a case, you can keep your backpack clean by protecting it with a rain cover.
If it gets dirty, you can remove it from the backpack and wash and dry it, so it is always clean.

A two-layered bottom pocket is designed to hold items that should be kept separate from other luggage.
The height of the pocket is 12 cm, but there is enough room in the interior fabric to accommodate items up to 20 cm in height.
The height of the pocket is 12 cm, but there is enough room inside to store items up to 20 cm high.
For example, dirty shoes or clothes. Spare clothes. Lunch box.

With strap fixing belt
After adjusting the belt to the length that suits you because it has a length adjustment belt for the back strap and a loop-shaped flat elastic at the end of the chest belt,
After adjusting the belt to the length that suits you best, please wrap the belt around in a circular motion to turn the flat elastic over.
This is a feature that has been used in baby carriers for a long time, to prevent the stretched belt from catching on fences or other objects that may cause the baby to lose 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.

15-inch PC pocket
The popular laptop size is 13 to 14 inches, but what size is your computer?
You may be looking for a bag to carry your PC based on the information that it is "00-inch compatible," but the size of the PC case is also important.
When storing your PC in a PC bag, we recommend that you use a PC case even if the bag contains shock-absorbing material.
A PC case is essential to protect against strong shocks in the event of an accident.
However, case sizes vary, and a 14-inch PC in a case may not fit in the dedicated pocket.
Therefore, we designed this backpack so that a 15-inch PC can fit in with about 25mm of room.
The buckle tape that holds the PC in place is attached from the top of the backpack not only for the strength of the tape, but also to accommodate an LCD tablet up to 15 inches in size, which is longer than the PC.

Lower handle
As an auxiliary handle to be used when moving the backpack on your back to and from the upper storage compartment, such as on trains and airplanes, or when moving the backpack forward with the backpack on your back.

Back carry-on and zipper pocket
The back of the bag has a carry-on and a zipper pocket for a long wallet.
Inside the zipper pocket is a solid pocket for sorting passcases, etc. and a 10mm D-ring, which can be used with the included spring strap to hold keys and other valuables, name holders, etc.
