FOB FACTORY
A brand inspired by vintage garments, rooted in workwear, military, and denim. Based in Kojima, Kurashiki City, Okayama—one of Japan’s leading production hubs—all processes are carried out domestically. Their aim is to create garments that customers will be glad they purchased even three years down the line.

Depth of color through vat dyeing
The fabric is a lightweight poplin—thin yet structured, with a smooth, dry touch that feels comfortable in spring and summer.
Finished with vat dyeing (sulfur dyeing), a type of garment dyeing that creates a rich, nuanced color. With wear, it develops a natural fade, allowing you to enjoy its aging process over time.
An open collar that feels effortlessly refined
The neckline features a slightly open collar, creating a relaxed yet refined look. Simply pairing it with a T-shirt adds an effortless look.
A flap pocket is placed on the chest, adding a subtle workwear accent to the otherwise minimal design.


A boxy silhouette, just right for now
A box silhouette with a relaxed width through the body. The square-cut hem allows it to look balanced even when worn untucked.
Pairs effortlessly with both wide and slim bottoms, and also works well as a light outer layer in spring.
Not too structured, yet not overly casual.
A piece that captures the balance of refined ease for everyday wear.
