288ZR-BKBK - 20oz "Secret Black" Selvedge Denim - Classic Straight

This Black/Black denim is ONI's iconic 20oz "Secret Denim" with a twist. The heavyweight fabric is woven at low tension, creating a rich texture with pronounced slub and irregularity. Featuring a double black finish achieved through sulfur dyeing, the jacket offers a deep, matte tone that will evolve uniquely with wear over time. The one-wash treatment ensures reduced shrinkage and a softer hand, making it easier to break in despite its substantial weight. This is probably the rarest of the "Secret Denim" collection. It is finished with black laurel wreath buttons and a deerskin leather patch, highlighting its thoughtful craftsmanship. This limited-edition, sold-out internet-wide piece showcases the perfect balance between heritage design and ONI's innovative denim expertise.

Fit Notes: Shop owner Tommy is wearing a size 34 in this Classic Straight fit. He has learned from past styles that he needs the room in the top box of the 34. This gave him. a little extra room in the waist and the leg opening he wanted for the Classic Straight style. It's a little more tailored than the Wide Straight, overall so we recommends sizing up once from what you normally wear. Tommy is 5'10," 165lbs, with a 32-33" waist.
