The ONI Denim Black x Olive Neat Straight jeans represent the enigmatic passion of master craftsman Oishi-san, who has dedicated over 60 years to perfecting denim artistry. These jeans showcase a unique 12.5oz low-tension selvedge denim woven on vintage shuttle looms. The distinctive color profile combines black sulfur-dyed warp with olive sulfur-dyed weft, creating a rich depth that will evolve into a unique patina with wear – similar to traditional indigo but with an entirely different character. A vibrant pink selvedge ID provides striking contrast against the dark fabric.
The Neat Straight fit offers a slim-fitting silhouette with comfortable high rise, good room through the seat, and relaxed thigh extending to a straight leg. Pre-washed to prevent shrinkage, these jeans provide immediate comfort while retaining the characteristically textured, slightly rough hand that ONI is renowned for. Every detail reflects Oishi-san's uncompromising dedication to quality, from the vegetable-tanned deerskin patch to practical features like hidden rivets and raised belt loops.
Fit Notes: These jeans have a standard sizing. We recommend choosing your usual size. However, as always, we recommend checking the size chart first to find your perfect size. It is unsanforized but one washed, so there will be no shrinkage. The waist will experience the typical stretching seen in ONI denim due to the low tension weave, although not as much as the secret denim. Expect approximately 1 inches of stretching.
