Slightly slimmer, straight model made of Zero+ denim. The silhouette is based on the S5000VX, but the inseam has been modified to be one inch deeper, and other aspects of the silhouette have also been tweaked for balance. The buttons used were newly created to mimic the color of "shakudo" metal with a well-worn black finish, which has been used for weapons and ornaments in Japan since ancient times. As the buttons are used, the luster settles down and a beautiful patina starts to appear, allowing you to enjoy changes in the look of the metal. The pocket bags are made of 8 oz. uneven thread denim, tougher than conventional fabrics. We plan to develop this as a semi-standard model in the future.
