FOB FACTORY
Based in Kojima, Kurashiki City, Okayama—one of Japan’s leading production hubs—FOB FACTORY is a brand rooted in vintage-inspired workwear, military garments, and jeans. Every process is carried out in Japan, with a commitment to creating clothing that customers will feel glad to have purchased even three years later.
High-Density Heavyweight Cotton Twill
While typical chino cloth is woven with single yarns in a twill structure, this fabric is made using finer two-ply yarns. By weaving these fine yarns at a high density, it achieves both firmness and durability. A smooth, finely textured weave gives the fabric a subtle sheen and an elegant character.
With continued wear, natural puckering develops over time, adding depth and allowing the garment to evolve with rich character.
Origin of “Weapon”
“Weapon” is a Japanese term derived from “West Point,” named after the fabric originally used for uniforms at the United States Military Academy in New York.
Classic details, thoughtfully updated
The front features a zip fly using a UNIVERSAL zipper. While originally designed with a button fly, it has been updated for ease of wear.
A coin pocket is placed at the front.
The back is finished with double welt pockets, and features an offset center belt loop. These details reflect classic U.S. Army trousers.
The inseam, outseam, and seat seams are finished with felled seams, increasing durability for long-lasting wear.
Tapered pants for versatile styling
Based on FOB’s popular baker pants silhouette, this design features a slim tapered shape. Suitable for casual outfits as well as jacket styling, it adapts easily across different settings.
The subtle luster of the fabric pairs not only with sneakers but also with leather shoes, offering a refined impression.

Staff comment
| ●Staff Height/Weight: 165cm / 64kg Wearing size: S / M Body type: Slim Thigh: Slim Fit (Waist): Just fit Length: Slightly long In size S, the waist fits just right without feeling restrictive. The overall silhouette is clean and streamlined, though the length runs slightly long for my height. I would adjust it with a half break or a roll-up. If I want a more relaxed fit, size M would also work well. |
| ●Staff Height/Weight: 171cm / 70kg Wearing size: M / L Body type: Standard Thigh: Standard Fit (Waist): Just fit Length: Just right Size M offers a perfect fit. There is a natural amount of room around the waist and hips, creating a clean straight silhouette without appearing bulky. The length sits just right when worn with shoes. For a more relaxed feel, size L is also a good option. |
| ●Staff Height/Weight: 177cm / 73kg Wearing size: L / LL Body type: Standard Thigh: Standard Fit (Waist): Just fit Length: Just right I would choose size L. The waist fits just right, and there is no tightness around the thighs, allowing for comfortable movement. The length is well-balanced—not too short or too long—maintaining a clean silhouette. If a looser fit is preferred, size LL can also be adjusted with a belt. |
| ●Staff Height/Weight: 181cm / 78kg Wearing size: LL / 3L Body type: Solid Thigh: Full Fit (Waist): Just fit Length: Just right With a solid build, size LL is the best fit. The waist sits just right, and there is sufficient room through the thighs without feeling restrictive. Size 3L feels overly voluminous overall, whereas LL provides a well-balanced silhouette, including the length. |
