Attribute deep dive
We break down what drove each score so you can weigh trade-offs.
Quality Analysis 90/100
This denim boasts excellent durability indicators, including a medium-weight Japanese sashiko fabric, robust chain-stitched hems, and hidden copper rivets on the back pockets to reinforce stress points. The use of custom branded nickel buttons further suggests a commitment to quality hardware that will withstand repeated wear.
Comfort Assessment 70/100
The 100% cotton composition and medium-weight fabric suggest a standard level of comfort, though the pronounced running stitch texture of the sashiko denim might introduce a slightly rougher hand feel compared to smooth denim.
Sustainability Impact Not Available
No sustainability indicators are present in the text, which describes the garment's material (100% cotton), construction, and dyeing process (sulfur-dyed). Therefore, a default score of 101 is assigned.

Garment details
Need-to-know info pulled from the retailer’s description, sizing notes, and care callouts.
Pure Blue Japan's sashiko denim is custom woven using a jacquard weave process, offering a medium-weight fabric with a pronounced running stitch texture. Produced in small batches, the denim is sulfur-dyed, allowing it to fade and develop a unique patina over time. Crafted in a classic five-pocket silhouette, the jeans are finished with custom nickel buttons, a deerskin leather patch, and Pure Blue Japan's signature indigofera leaf embroidery.
