Old indigo goes green. Decades of oxidation give deadstock vintage denim a cast that fresh indigo never has — muted, slightly green, closer to plant-dyed cloth than to a modern dip. ONI's Greencast denim builds that color in from the start: the yarn is dyed in indigo as usual, then given a green dye at the very end of the process, so the fabric arrives looking like it has spent fifty years asleep in a warehouse, and ages in the same direction as the vintage pairs it recalls.

The weave is pure ONI. This 15oz fabric is defined by its roughness and pronounced weaving irregularity, the product of loosening the thread tension to the limit and running the shuttle slowly on old power looms that Oishi-san has repaired again and again, breaking many shuttles along the way. That controlled unevenness is what the brand does better than anyone, and it is what gives the surface its depth and its fades their character. Unsanforized and one-washed.

The 622 is ONI's relaxed tapered fit: a mid rise, extra room through the seat and thigh, then a strong taper from the knee to a narrow 17 cm (6.7") leg opening on a size 31–32. It carries the comfort of a wide cut while keeping the profile sharp toward the hem.

Construction follows the house standard: ONI's custom copper doughnut buttons, hidden rivets on the back pockets, raised belt loops and a vegetable-tanned deerskin patch, with the selvedge ID at the outseam. The one-wash finish means no further shrinkage is expected. Made in Japan.

Fit Notes: This model runs slightly large, a touch more than usual for the 622: the waist measures about 2" over the tagged size. Compared to most global American brands, we recommend sizing down one from your usual size for the intended fit, or taking your usual size if you prefer more room through the top block. The denim is unsanforized but has been one-washed, so no further shrinkage is expected. With regular wear, the waistband will stretch approximately 1 inch, allowing the fit to settle comfortably over time. We don't recommend going down more than one size, as starting too tight may cause discomfort and alter the intended fit of the garment. As always, we strongly recommend checking our size chart to find your perfect size.
