Pure Blue Japan applies a "Used" wash treatment to the brands signature 14oz slub selvedge denim. The wash treatment mimics patina developed through years of intensive wash and wear. Pure Blue Japan's 14oz denim makes use of irregular slub yarns, woven on vintage shuttle looms at low-tension for a deeply textured fabric with a natural charm. Finished with custom hardware, a deerskin natural leather patch, and the signature Pure Blue Japan indigofera leaf embroidery.
