The Pure Blue Japan KS-15oz-019 jeans represent a masterful celebration of traditional Japanese Kasuri dyeing techniques. These exceptional jeans feature a 15oz unsanforized denim with distinctive varied indigo tones and undyed yarn accents that create natural streaking throughout the fabric. Often called the "Slub Masters," Pure Blue Japan demonstrates their expertise through careful yarn selection and precise calibration of vintage shuttle looms. The result is a fabric with remarkable texture and character that will evolve beautifully with wear.
The relaxed tapered fit provides generous space through the top block and thighs while maintaining a strong taper from the knee down. Each pair includes premium details like blue selvedge ID, goatskin leather patch, and PBJ's signature leaf embroidery on the back right pocket. One-washed for immediate wear while preserving texture, these jeans offer a perfect balance of comfort and distinctive character. The KS-15oz-019 exemplifies Pure Blue Japan's commitment to preserving traditional Japanese textile techniques while creating contemporary garments with exceptional artisanal craftsmanship.
Fit Notes: We usually recommend sizing up for PBJ jeans, but in this case, the Kasuri model is true to size. We suggest selecting your usual jeans size. However, as always, we recommend checking the size chart first to find your perfect fit. These jeans have been one-washed, so there will be no further shrinkage.
