The Samurai Jeans S510XX21ozII “Cho-Kiwami” represents the pinnacle of heavyweight Japanese denim. Woven on vintage wooden shuttle looms by master artisans, this fabric blends U.S. and Australian cotton into a unique 21oz selvedge denim. Using bold #4.5 x #4.5 slubby yarns, it achieves an exceptional texture and depth, while the signature red and gold lamé selvedge ID symbolizes the unmatched craftsmanship behind every pair.
Rich in thoughtful details, the Cho-Kiwami features “Syogyomujo 諸行無常” jacquard pocket linings, custom iron sunrise buttons, and a sheep leather patch, each element adding heritage character and refinement.
Cut in a regular straight silhouette with a mid-rise waist, these jeans deliver timeless versatility—offering comfort, durability, and style whether dressed up or worn casually. A true statement piece, the S510XX21ozII embodies Samurai’s dedication to pushing denim to its limits.
Fit Notes: Like many Samurai Jeans, this model runs slightly small in the one-wash version. We generally recommend going up one size from your usual. However, we always suggest checking the size chart to ensure the best fit. The denim is unsanforized but one-washed, so no further shrinkage will occur.
