ONI Kase 鬼枷染

Kase employs a new innovation that combines natural indigo kase-zome (hank dyeing) with rope-dyed core techniques, creating a rich, three-dimensional texture and uneven color depth. This is especially rare due to its fading ability, while all other natural indigo hank dyed denim remains unchanged in color through wear.

This 16oz fabric created by master Oishi-san at ONI delivers natural fading over time due to its slubby, ultra low-tension weave. It stands out for blending historical dyeing methods with modern denim innovation. 

What is Hank Dye?

Hank dyeing dyes cotton yarn in loose skeins (hanks) rather than in long, tensioned ropes. The yarn is bundled, tied, and repeatedly immersed in indigo vats, allowing dye to penetrate slowly and unevenly.

Unlike modern rope dyeing—which prioritizes speed, consistency, and shallow dye penetration—hank dyeing accepts variability as a feature, not a flaw.

ONI Coverall Jacket

The Selvedge Chambray Coverall jacket draws inspiration from the classic late 19th-century French chore coats, reimagined for today with a more tailored silhouette. Featuring shorter sleeves and a cropped body, it delivers a cleaner, more polished appearance while preserving the rugged durability and traditional workwear spirit. It’s a piece that strikes the right balance between old-world heritage and modern style.
