The Flat Head FN-OJ-SD001 12oz Denim Jacket

A faithful tribute to iconic 1940s WWII wartime denim jackets, the The Flat Head FN-OJ-SD001 combines authentic vintage detailing with the exceptional craftsmanship that has made The Flat Head a benchmark in Japanese denim production.Constructed from 12oz Japanese selvedge denim, this jacket is woven on traditional shuttle looms using 100% Zimbabwe cotton and irregular slub yarns, creating a rich texture with natural character. The lightweight fabric offers a comfortable, shirt-like feel while retaining the durability and aging potential of classic denim. Deeply rope-dyed indigo warp yarns ensure striking fade patterns that become more pronounced with wear, revealing a unique patina that reflects your journey.

This is a one-wash version of The Flat Head's unsanforized denim, meaning shrinkage has already been removed, allowing you to choose your size with confidence.
