The ONI Denim 03500-8CBE Coverall translates one of the brand's most distinctive summer fabrics into a piece designed for transitional wear. Cut in a classic chore coat silhouette – clean, functional, and highly wearable – the coverall layers effortlessly over a shirt or knit, making it an ideal companion for shoulder 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.

The result is a fabric with color on both sides and, thanks to the doubled dye content, a richer, more dimensional fading character as the garment ages. 'Betacham' – from the Japanese 'beta-na' (ベタな), meaning plain or uniform – reflects the intentionally flat, single-tone visual of the cloth, a deliberate departure from the two-tone character of standard chambray.
Practicality remains at the core of the design. The coverall features dual chest pockets – including an internal pocket for added security – alongside spacious hip patch pockets. Construction is finished with custom ONI copper donut buttons, durable contrast stitching visible along the placket and seams, and signature branding details that reflect the brand's commitment to craftsmanship.
