Japanese bag brand ace./Ace has added a top-grade model, the "Gadgetable DP2 4U," to its "Gadgetable" series of high-performance business backpacks, which are made in Japan.
From Wednesday, April 9th to Tuesday, April 22nd, Isetan Shinjuku Store, Men's Building B1F Bags will be offering a pre-sale of the "Gadgetable DP2 4U," which is scheduled to be released on Wednesday, April 23rd, as well as hosting "Harness Fit Lab," an experiential event that proposes the correct way to wear a business backpack.

Choose from 4 types of shoulder harnesses to find the perfect fit for your back!

"Gadgetable DP2 4U"
62,700 yen (H42 x W30 x D14(18)cm)
*Available exclusively at Isetan Shinjuku store. *General sales begin April 23, 2025 (Wednesday).

A business backpack that you carry every day needs to have a design that suits business situations and reduce the strain on your body caused by carrying a backpack.
The newly released "Gadgetable DP2 4U" inherits the design and functionality of the popular "Gadgetable" series of business backpacks, which condense storage capacity into a slim body, while achieving a more comfortable fit through the shape of the shoulder harness.
Developed by ace based on measurements of male monitors of various body types, the "4U Harness" is categorized into four types—S (Slender), P (Power), B (Balance), and M (Max)—not based on appearance factors such as body shape or build, but on differences in back length and shoulder thickness, allowing you to choose the shoulder harness that best suits you.

It also features side pockets that can hold water bottles or folding umbrellas, and an expandable band function that allows you to widen the gusset.

At the "Harness Fit Lab" event, you can actually try on the "Gadgetable DP2 4U." We will also be offering a service where we measure your back and suggest a shoulder harness tailored to your individual needs.
Furthermore, on April 12th (Sat), April 13th (Sun), April 19th (Sat), and April 20th (Sun), Dr. Zenta Wakao (Engineering), the developer of the product and from Ace Lab, Ace Corporation, will be visiting the store. This will be an opportunity for you to experience the "Gadgetable DP2 4U" ahead of time, so please look forward to it.
