ONI's Secret Denim is legendary for its unmatched texture, softness, and character. First introduced in 2012, it is crafted by Oishi-san using an exclusive process with extra-thick yarns from three cotton types, woven at ultra-low tension on vintage shuttle looms. The result is a 20oz unsanforized fabric with extreme slub, a rough yet soft feel, and a distinct hairy texture.
This double black version features both warp and weft sulfur-dyed for a deep, rich color. Despite its heavy weight, the fabric feels surprisingly comfortable. Its uneven texture creates striking contrast as it fades, unlike typical flat-looking black denim. Production is especially rare, as the specialized dyeing facilities capable of handling these thick yarns are expected to close.
Combined with its unique craftsmanship, this makes Black Secret Denim a highly collectible piece. The Regular Straight fit delivers a timeless, easygoing silhouette. With a medium-high rise and a consistent width from the thigh down to the hem, it offers a comfortable amount of room without excess bulk.
The straight leg creates a clean, balanced look that works effortlessly for everyday wear. - Style: 288ZR-BKBK Relax Tapered- Fit: Regular fit - Straight leg - Mid rise- Color: Black- Material: 100% cotton- Made of 20oz Japanese unsanforized selvedge denim- Washed once- Red/White selvedge ID- Warp and weft black dyed- Button fly- Leather patch- Made in JapanOur model is 180cm, 80kg - wears size 36/34 31 32 33 34 36 38 Waist 40,5 42 44 46,5 Inseam 86 86 86 87 Thigh 30 30 31 34 Knee 22,5 24 25 25 Leg Opening 21,5 21,5 22 22,5 Front Rise 30 30 30 31
