Quality Analysis 100/100
This denim is built for the long haul, featuring an impressive 18oz heavyweight fabric and robust construction details like hidden back pocket rivets and chain-stitched hems, ensuring excellent resistance to wear and tear. The use of custom branded copper rivets further reinforces stress points, promising exceptional longevity.
Comfort Assessment 60/100
This garment is made from heavyweight 18oz denim, which suggests a rigid and potentially restrictive feel, especially since it is 100% cotton with no mention of stretch. The unsanforized fabric has been given one wash to remove shrinkage, which may offer a slightly softer starting point than raw denim.
Sustainability Impact Not Available
This garment lacks any explicit sustainability indicators, such as certified organic or recycled materials, making it impossible to assess its environmental or ethical impact based solely on this description.

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.
