Attribute deep dive

We break down what drove each score so you can weigh trade-offs.

Quality Analysis 100/100

This denim is built for the long haul, featuring a substantial 15oz slub selvedge fabric and robust construction details like chain-stitched hems and hidden copper rivets on the back pockets, ensuring excellent resistance to wear and tear. Furthermore, the use of custom branded nickel buttons and the reputable Pure Blue Japan brand name strongly indicate superior material quality and craftsmanship.

Comfort Assessment 70/100

This denim is made from 100% cotton, which offers a neutral starting point for comfort, but the heavyweight 15oz fabric and rigid construction suggest a break-in period will be required before maximum comfort is achieved.

Sustainability Impact Not Available

This garment provides no explicit sustainability indicators, such as certified organic materials or ethical production claims, making it impossible to assign a score based on environmental or social impact.

Garment details

Need-to-know info pulled from the retailer’s description, sizing notes, and care callouts.

The new Kasuri denim from Pure Blue Japan reinvents their ultra-textured Extra Slub Series denim through traditional Japanese dyeing techniques. Made in small batches in Japan, the denim's subtly varied surface color comes from an intentional uneven dye on the warp yarns, and is accentuated by the wild yarn size variations throughout the fabric. As with other styles in PBJ's catalog, the Kasuri Selvedge is woven on an old-world shuttle loom using a specialized slow weaving technique to produce the unique texture the brand is renowned for. Finished with custom nickel buttons, a deerskin natural leather patch, and the signature Pure Blue Japan indigofera leaf embroidery.
