MASTER-PIECE
Founded in 1994, this Japanese brand blends high-level functionality with a design-driven approach, creating bags that reveal thoughtful details with use.



Eco-Friendly Performance Fabric
The main fabric is "ECOPAK™," produced by CHALLENGE SAILCLOTH in the U.S. This recycled polyester offers outstanding durability and waterproof properties while remaining environmentally friendly.

"ECOPAK™" features a multi-layer structure that achieves high durability and water resistance without using harmful coating materials. Additionally, the fabric itself can be recycled after use.





Minimalist Functional Design
On both sides of the main compartment, card pockets provide organized storage. Despite its minimal look, each pocket can hold about 3 to 5 cards.







The front pocket includes a key hook, allowing quick access to keys or other essentials.





The back panel features a coin pocket, making it convenient as a compact wallet for light outings. A loop is also included for attaching a carabiner, enhancing usability when paired with a bag or pants.









Versatile Usage
Pair it with the brand's smartphone shoulder pouch for a coordinated look.
