Following the evolution of ultra slubby and neppy work of the ONI Asphalt and ONI Super Rough Secret Denim. A huge breakthrough is again achieved by this highly anticipated work - Crushed Concrete Denim. This fabric is considered a lighter version of the "Super Rough" but features a darker indigo hue, making these jeans versatile for many occasions. Despite its lighter weight, the Crushed Concrete Denim maintains a relatively subdued yet distinctive appearance compared to its heavier 20oz counterparts, offering comfort for year-round wear.

These days, the only spinning mills in Japan capable of producing the kind of yarn ONI requires are often small, family-run operations with decades of experience. Once the yarn is spun, only a handful of dyeing houses have the expertise to rope-dye such thick yarns in black—especially for creating heavyweight denim. That’s why fabrics like these are becoming increasingly rare in the market. Using black-dyed warp and black-dyed weft is a bit like ordering a double espresso when you really want a kick—it’s bold, intense, and gets the job done. This double-dye process allows the fabric to fade both inside and out, creating deeper contrast and making the aging process even more interesting and rewarding.

Typically, achieving a pronounced slub effect in denim with a mid to high weight under 16oz is challenging due to the limitations imposed by yarn thickness, or yarn count. Mr. Oishi-san, the owner of ONI, has masterfully created CCD with an unprecedented level of texture that cannot be simply defined as slubby or neppy. The yarns are custom made at small historical spinning mills, their expertise has made it possible to produce high quality yarns that the major companies were unable to produce. Through a special blend of cotton, a new, secretive type of yarn was developed specifically for this innovative fabric.

To describe its organic appearance, terms like gravel or granite come to mind, but 'crushed concrete' is just one way to express the unique characteristics of this denim. There's definitely more to explore with this fabric, whose fading potential and the depth of structure promise an unparalleled wearing experience.

“When I first tried to make an original ONI denim 20 years back. I created a denim that is so textured there are 30-50% of fabric unusable due to its defect rate. I had to give up that recipe to produce a denim with only 50% of its original texture.” - Oishi-san

“Do you feel with the birth of Crushed Concrete Denim, is it something closer to that super prototype denim made 20 years ago?” - Sven, Store Manager

"Yes. We even surpassed that limit." - Oishi-san
