Quality Analysis 100/100
This denim is built for the long haul, featuring an extremely heavy 18oz fabric weight 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 further reinforces stress points, promising years of reliable use.
Comfort Assessment 70/100
The comfort score defaults to 70 because the text provides no specific comfort indicators, such as stretch claims, seam types, or fabric softness.
Sustainability Impact 80/100
This garment features natural indigo dye, a strong positive indicator for sustainability compared to conventional synthetic dyes, suggesting a lower environmental impact. However, the text provides no other evidence regarding material sourcing or ethical production practices.

Garment details
Need-to-know info pulled from the retailer’s description, sizing notes, and care callouts.
Samurai's Ai-Benkei denim reinterprets their specialty Ai Plus fabric through the use of new cotton and indigo dying techniques. Crafted on antique looms, this 18oz denim combines Samurai's original home-grown cotton with cotton from the brand's popular "Benkei" 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.
