FOB FACTORY
A brand inspired by vintage clothing, rooted in workwear, military wear, and jeans. Headquartered in Kojima, Kurashiki City, Okayama Prefecture—one of Japan’s foremost production hubs—all manufacturing processes are carried out entirely in Japan. FOB Factory strives to create garments that customers will feel glad they chose, even three years after purchase.

Original VAT-Dyed Moleskin Fabric
This fabric reproduces the moleskin once used in the U.S. military flight jacket “B-9.” Woven with three-ply yarns, the high-density material offers both strength and flexibility, with remarkably little nap—so little that you might wonder, “Is this really moleskin?”
With its unique sheen and VAT-dyed finish, the fabric develops character as it ages. The longer it is worn, the richer and more nuanced its appearance becomes.
Meticulously Considered Details
The neckline features a high snap-button design, while a drawcord allows the hood fit to be adjusted, helping to block out wind.
The front is constructed with a snap-button and zip storm flap to prevent wind penetration. A practical double zipper allows for subtle changes in silhouette.
Large pockets are placed on both sides, each spacious enough to hold items such as a 500ml bottle with ease.
The cuffs are equipped with adjusters; cinching them creates a well-defined silhouette that contrasts neatly with the volume of the sleeves.
The drawcord at the waist allows you to adjust the silhouette—an appreciated detail.
The hem features an M-51–inspired fishtail design, and like the waist, its shape can be adjusted with a drawcord.
Originally designed by the U.S. military in 1951, this piece has been updated to suit a modern style. The slightly shortened length and relaxed silhouette blend seamlessly into a wide range of outfits, offering excellent versatility. Suitable not only for casual wear, it also pairs well with suits and tailored jackets.

●Staff Height / Weight: 165cm / 64kg Wearing size: S Body type: Slim (narrow shoulders) Fit: Relaxed Length: Just right Wearing size S gives a relaxed silhouette with just the right amount of room. The original M-51 tends to have a long length that can feel overwhelming, but this version has been subtly shortened, making it well-balanced even for a smaller frame like mine. The fabric is surprisingly supple for moleskin, and it doesn’t feel heavy at all, which is a nice bonus. |
|
●Staff Height / Weight: 171cm / 70kg Wearing size: M Body type: Standard Fit: Just right Length: Just right Size M fits perfectly. There’s enough room in the body to layer a thick sweater or jacket underneath without restricting movement. The unique sheen from the VATDYE process gives it a refined look despite its military roots, making it useful for both on- and off-duty wear. The double zipper, which allows you to adjust the silhouette, is another big plus. |
|
●Staff Height / Weight: 177cm / 73kg Wearing size: L Body type: Standard Fit: Just right Length: Just right I’d choose size L. There’s no tightness around the shoulders or body, and the sleeve length is spot on. Slightly tightening the waist drawcord removes any bulk and gives it a more modern silhouette. The large pockets are very practical, making it ideal for going out hands-free. |
|
●Staff Height / Weight: 181cm / 78kg Wearing size: XL Body type: Solid build (broad shoulders) Fit: Relaxed Length: Just right With my broader shoulders, I chose size XL. There’s no tightness around the shoulders, and the length lets you fully enjoy the fishtail design. The high-density moleskin fabric is extremely tough and delivers the reassuring quality you’d expect from FOB. It looks like the fabric will develop character with wear, aging beautifully into a vintage-like finish. |
