Fit Notes: This model fits true to size for Oni and most Japanese brands. Compared to most global American brands, a size 42 fits similarly to a Large. As always, we strongly recommend checking our size chart and comparing it with your best-fitting jacket to find the perfect size. The fabric is unsanforized but the jacket has been one-washed, so no shrinkage is expected.

This coverall showcases a more understated side of ONI, reinterpreting their signature fabric through a sulfur-dyed olive warp that brings a fresh perspective to traditional selvedge denim. Woven on vintage looms at low tension, the 18oz fabric retains the brand’s hallmark irregularity while introducing a more muted, earthy character.

The texture is unmistakably ONI—slubby, uneven, and full of life—with a dry, slightly rugged hand that softens progressively with wear. Unlike indigo denim, the olive tone evolves differently over time. Instead of high-contrast fades, the fabric develops subtle tonal variations, revealing depth and complexity through gradual aging. The result is a piece that feels more refined and quietly expressive, perfect for those who appreciate a less conventional fade journey.

Designed following classic chore coat principles, the silhouette is clean, functional, and highly wearable. It layers effortlessly over a shirt or knit, making it an ideal companion for transitional seasons. Whether paired with indigo denim and a white tee or worn as part of a tonal outfit, it delivers a grounded, heritage-inspired look with a contemporary edge.

Practicality remains at the core of the design. The coverall features dual chest pockets—including an internal pocket for added security—alongside spacious hand pockets at the waist. Construction is finished with custom ONI copper doughnut buttons, durable stitching, and signature branding details that reflect the brand’s commitment to craftsmanship.
