Dulles backpack equipped with a "quick open function" that allows you to open and close with one touch due to the frame structure.

The main material is recycled nylon made from recycled fishing nets.
Discarded fishing nets are dried, washed, and compressed at a fishing net collection company in Hokkaido, and then finely ground and processed into recycled plastic particles at the material manufacturer's Ichinomiya factory in Aichi Prefecture. The grains are processed into thread and woven into nylon fabric.
The handle and bottom are made of cuore, a synthetic leather that is highly durable and has excellent environmental performance.

The main storage can be opened wide with one touch, giving you a wide view of the interior and making it easy to take out stored items. The secret to easy access is the good balance of being able to stand on its own while the bag is open. It's large enough to comfortably fit an A4 file, and has a wide gusset, so it's large enough to store all your luggage in one bag. A 13-inch PC can fit in the back pocket. By fastening the belt with a hook-and-loop fastener, you can prevent your PC from popping out. The front side has a 2-divided zipper pocket that allows you to neatly store small items. With carry-on function.
*Note: Laptop computers may not fit depending on their size or if a protective case is attached.
