Attribute deep dive
We break down what drove each score so you can weigh trade-offs.
Quality Analysis 100/100
This denim is built to last, featuring an extremely heavy 18oz selvedge denim fabric and robust construction details like chain-stitched hems and hidden back pocket rivets, which significantly reinforce stress points. The use of custom branded iron buttons further suggests a commitment to high-quality, durable hardware.
Comfort Assessment 70/100
The comfort score defaults to 70 because the text provides no specific comfort indicators, such as stretch claims, soft fibers, or seam details, to adjust the baseline.
Sustainability Impact 90/100
This garment demonstrates strong sustainability practices by using homegrown Japanese cotton and a natural Kuri Tamba chestnut overdye, with both materials sourced from the same local area. The entire production, from seed to stitch, is a closed-loop "Samurai Cotton Project" made entirely in Japan.

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.
