Japan Blue Jeans Type 1 Denim Jacket - 16oz Selvedge

Type I is where the Japan Blue jacket story starts, the shape that came before the two-pocket version most people picture when they think denim jacket. At 16oz this is heavy cloth, woven and dyed the way Okayama mills have always done it, and it wears more like a work jacket than a fashion piece. Indigo sits deep in the yarn here, so the fading that comes later happens gradually, favouring the collar, cuffs and pocket edges first.

The cut is close to the original, single chest pocket, straight hem, no pretence. It holds its shape when new and takes a few wears to settle in, which is normal for denim this heavy. Layer it over a tee or a chambray shirt and let it do the work.
