Attribute deep dive
We break down what drove each score so you can weigh trade-offs.
Quality Analysis 100/100
This denim is built for the long haul, featuring an extremely heavy 18oz Sasayama selvedge denim fabric and robust construction details like hidden back pocket rivets and custom branded iron buttons, ensuring exceptional resistance to wear and tear. Further enhancing its longevity is the use of chain stitched hems, a strong indicator of quality manufacturing designed to withstand repeated stress.
Comfort Assessment 60/100
The comfort score is based on the garment's construction and material, which includes a relaxed tapered fit that offers room in the thigh, suggesting less restriction, but the 18oz heavyweight denim and 100% cotton composition without stretch may limit mobility.
Sustainability Impact 90/100
This garment scores highly because it uses homegrown Japanese cotton and a natural Kuri Tamba chestnut overdye, demonstrating a commitment to local sourcing and reduced chemical impact. The entire process, from seed to stitch, is completed in Japan, supporting local economies and reducing transportation emissions.

Introducing the Shizen Selvedge Denim, the first collaboration between Samurai Jeans and Blue Owl. This collection combines Samurai's homegrown "Cotton Project" cotton with a range of natural overdyes, made exclusively for Blue Owl. This iteration is dyed using Kuri Tamba, a dye derived from Tamba Chestnut skins. The chestnuts used to dye this fabric are grown in the same area as the cotton for this series.Grown, harvested, and woven in Japan, this collector's edition denim was originally conceptualized as a passion-project by Samurai Jeans founder Toru Nogami to produce a completely made in Japan denim from seed to stitch. Fittingly named the "Samurai Cotton Project," this 18oz selvedge denim sports a highly-visible slub and nep. The jeans come packed with symbolism referencing the brand's traditional warrior ethos including special edition iron buttons, jacquard pocket bags, back pocket rivets, and a custom co-branded leather patch.
