Attribute deep dive
We break down what drove each score so you can weigh trade-offs.
Quality Analysis 100/100
This garment is built for the long haul, featuring an extremely heavy 18oz selvedge denim fabric and robust construction details like hidden back pocket rivets and chain-stitched hems, ensuring exceptional resistance to wear and tear. The use of custom branded copper rivets and iron buttons further reinforces critical stress points, promising enduring quality.
Comfort Assessment 60/100
The comfort score is low due to the extremely heavy 18oz denim, which is rigid and lacks any mention of stretch or adaptive fit elements.
Sustainability Impact Not Available
This garment lacks sufficient evidence to assess its sustainability, as the text focuses on material weight, traditional craftsmanship, and brand symbolism rather than environmental or social impact claims. The default score of 101 is assigned.

Garment details
Need-to-know info pulled from the retailer’s description, sizing notes, and care callouts.
Samurai's Ai-Plus denim is the brand's original denim, dyed using a pure indigo mix for a rich, natural indigo color that fades similar to traditional indigo denim. Crafted on antique looms, this 18oz denim combines Samurai's original Japan-grown cotton with American cotton denim to create a wealth of visible texture. The denim is woven using hand-dyed yarn, which sports a beautiful varied blue color through use of two distinct shades of indigo. In typical Samurai fashion, the jeans are packed with symbolism referencing the brand's traditional warrior ethos, and come finished with premium details such as raised belt loops, back pocket rivets, and a special edition leather patch hand dyed in natural indigo.
