Pure Blue Japan Indigo Herringbone Track Jacket

Size Guide
For that ultimate indigo top, choose this, no sweat!

As some of Japan’s best indigo craftsman, PBJ has specially developed their indigo thread dying techniques to make up for textured garments with many shades of indigo!

Unlike over-dying techniques, PBJ’s technique allows for the threads to retain a white core, meaning with the time you’ll see some strong contrast and enhanced, dotted texture.

Using vintage knitting machines, the sweat fabric has a hidden herringbone texture which will come up little by little with wear and wash.

For added contrast, the sleeves, under-arm, collar and hem have been finished with fabric from a vintage jacquard machine.

Match your environment, adjust that two way zip and stay comfy!
