Freezer Addition Daypack 31L

1 + 2 ≠ 2

Considering the current production environment where "subtractive" 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 daypack type features a front pocket made of heat-retaining and cooling material to maintain the temperature of food and drinks, and the studs designed on the front can be removed and replaced with reflectors.

While product manufacturing in Japan is of extremely high value, produced by skilled craftsmen under thorough quality control by the organization, it is necessary to implement a "subtractive" design that keeps the specifications, compactness, lightness, and price to the bare minimum in order to make it 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 elements than what is generally expected of a bag.

ADDITION BAG doesn't end there.

By removing the front panel of the square type, it can be combined with the daypack type, and by combining the two types into one bag, not only can you increase the capacity, but you can also organize your belongings as if it were a bag with dividers, allowing for various uses depending on the user and the situation.

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

〈Bag Shape〉
Utilizing the know-how cultivated from our previous bag developments, we have reproduced highly sought-after shapes. We have re-examined the balance of the bare minimum functionality, durability, and lightness with a subtractive design, resulting in the best minimalist bag.

〈Material〉
Made with eco-friendly Cordura, which is considerate of the global environment, people, and animals. The zipper uses a larger 10-coil design for smoother opening and closing and increased durability. The pull tab is an original design, and the eyelet accent has also been completely redesigned and positioned.

Repairs such as re-sewing and replacement of eyelet parts and zippers are standard. We have set up a repair environment so that you can use your favorite bag for a long time.
