Features:

"Gadgetable" is a high-performance business backpack born from the concept of "designing a comfortable commuting environment." Its slim design makes it less obtrusive even in crowded situations, and it offers an excellent balance of functionality, ease of use, and design.

The "Gadgetable DP2 4U" is a top-grade model made in Japan, meticulously sewn one by one by skilled Japanese craftsmen. The four types of "4U Harnesses," uniquely developed based on measurement data, provide a comfortable carrying experience.

[What is the 4U Harness?]

The "4U Harness" consists of four types of shoulder harnesses developed based on measurement data from various male monitors with different body types and builds.

Instead of visual elements like body shape or fleshiness, the four types—S (Slender), P (Power), B (Balance), and M (Max)—are classified by differences in back length and shoulder thickness, allowing you to choose the optimal shoulder harness shape for yourself.

・S (Slender): For those with slender and compact shoulders.

・P (Power): For those with sturdy and thick shoulders.

・B (Balance): For those with average shoulders and height.

・M (Max): For those with a large build and thick shoulders.
