Attribute deep dive
We break down what drove each score so you can weigh trade-offs.
Quality Analysis 90/100
The exceptional durability of these jeans is immediately apparent, thanks to the use of 20oz unsanforized selvedge denim, which is significantly heavier and more robust than standard denim. Further reinforcing their longevity are the back pocket rivets and custom engraved hardware, ensuring these jeans are built to last through years of wear and fading.
Comfort Assessment 60/100
The comfort score is low due to the extremely heavy 20oz selvedge denim, which is inherently rigid and lacks stretch, though the one-wash tempi treatment does offer the convenience of being ready to wear immediately without soaking.
Sustainability Impact 80/100
This garment includes a strong positive indicator: a custom vegetable tanned leather patch, which is generally less harmful than conventionally chrome-tanned leather. However, the text provides no other specific sustainability claims regarding materials, production, or labour.
