ORIGIN: Made in Japan
A straight-cut jean made from 12.5oz African cotton selvedge denim. Woven in Kojima, Japan, this soft and supple fabric incorporates natural, unbleached brown cotton for a rich, vintage look. Both the brown/white weave and indigo rope dyeing will produce a more traditional, earthy fade evolution with extended wear.
The J304 features a curved waistband designed to mimic the natural contour of the waist—a subtle detail that enhances comfort and delivers a more flattering fit. Signature Japan Blue Jeans detailing includes a donut-cut top button, royal blue inseam, and premium veg-tanned leather patch.
Sanforised and one-washed. No shrinkage expected.
