Japan Blue Jeans Organic Drill Coverall Jacket - Olive Drab

The coverall jacket draws from the tradition of Japanese workwear, a full-fronted garment built for practical use, with the proportions and details that defined workshop and factory clothing through much of the twentieth century. Japan Blue works from Kojima, Okayama, a region with deep roots in Japanese textile production, and applies that heritage to each piece they make.

This version is cut in olive drab cotton and made entirely in Japan. Olive drab sits in the same territory as field and military work clothing, a muted, grey-green tone that has served as a practical neutral across decades of workwear history. The construction is considered: seam placement, pocket positioning, and closure hardware all follow the logic of a working garment. It wears loosely over layers and carries its shape well as the fabric breaks in.
