Square Addition Backpack 32L

1 + 2 ≠ 2

Considering the current production environment where "subtraction" design is the mainstream, we have created a multi-functional bag based on the concept of "addition."

The "ADDITION BAG" is a model packed with various functions, including design and humor, based on the concept of "addition" (1 + 1 ≠ 2).

The square type has shoulder straps attached to both sides, allowing two people to carry it from either side. The detachable front panel is reversible, and by attaching the detachable nylon tape, it can also be used alone.

It transforms into a convenient drawstring bag type, perfect for carrying just a PC or tablet.

While product manufacturing in Japan is of extremely high value, produced by skilled craftsmen under strict quality control by organizations, it's also necessary to carefully check the specifications and implement a "subtractive" design that keeps compactness, portability, and price to the bare minimum in order to make the products more accessible to customers.

With respect for the modern manufacturing environment and those involved, and as an antithesis to the possibility that their efforts may not be rewarded, we have created two types of bags—a square type and a daypack type—that "add" many more features than what is generally expected of a bag.

But the ADDITION BAG doesn't end there.

By removing the front panel of the square type, it can be combined with the daypack type, allowing you to increase capacity and organize your belongings as if it were a bag with dividers, enabling various uses depending on the user and situation.

The Addition Bag offers hundreds of ways to use it.
Enjoy your own unique bag style.
