FOB FACTORY / F3510 Heavy Flannel Work Shirt
This season's heavy flannel from FOB FACTORY is unique in both appearance and comfort!
Traditional processes used for wool tweed are applied to 100% cotton fabric, with three-ply threads dyed in different colors to create a melange effect.
In other words, it's heavy yet lightweight, vintage-inspired yet machine-washable for easy care. This shirt combines the durability of a work shirt, classic sophistication, and modern comfort—all in one piece. It's our recommended “sophisticated” shirt.

FOB FACTORY
Inspired by vintage clothing, FOB FACTORY is based in Kojima, Kurashiki City, Okayama, one of Japan's leading production hubs for workwear, military, and denim. The brand aims to create clothing that customers will be glad they bought even three years later. 
Luxurious Wool Tweed × Cotton Melange
The “twist” technique used for wool tweed is applied to cotton. Three cotton yarns are dyed in different colors and twisted together to create a deep, melange effect.
From a distance, the fabric has a rich texture, and up close, it reveals depth and nuance. Plus, with zero itchiness, it's seasonless, easy to wear, and machine washable. Experience this one-of-a-kind fabric.
Attention to Detail in Adult Workwear
The front features cat-eye buttons reminiscent of vintage work shirts. Two flap pockets are placed on the chest, and the shirt is constructed with durable triple-stitched seams.
Combining the rich texture of the fabric with authentic work details, this piece shines whether worn alone or layered. It's designed to work with both casual and more refined styles.
Exquisitely “Just Right,” Modern Regular Fit
While maintaining a vintage nuance, the fit has been updated for modern times.
The body has just the right amount of room, and the length is perfectly balanced. The round-cut hem looks great whether worn tucked or untucked. This versatile silhouette works well for both casual and refined outfits.
