Workwear is synonymous with both rugged durability and timeless style, and the ONI Secret Denim Black Coverall Jacket embodies these traits effortlessly. Known for his skill in reinterpreting American workwear through a distinctly Japanese lens, Oishi-San's designs are always reliable, unique, and practical. This heavyweight coverall blends form and function with a durable 20oz fabric and practical pockets, perfect for layering over everything from a hoodie to a tee. It features one inner and one outer breast pocket and two handwarmer pockets at the waist for added convenience.
Originally launched in 2012, Secret Denim has become one of the most sought-after fabrics among Denim Heads due to its incredible softness and unique texture. This exclusive double black version retains all the characteristics of the original, woven with three different types of cotton and extra-thick yarns at ultra-low tension on vintage shuttle looms. The result is a beefy, unsanforized, and incredibly textured 20oz fabric with fantastic slub, roughness, and a hairy finish. The warp and weft of this version are sulfur-dyed black, delivering an intense, deep color that will evolve beautifully over time.
Crafted with precision, the coverall is finished with black enamel-coated steel buttons, a selvedge hanger loop, and selvedge pockets, ensuring both durability and premium quality.
With the impending retirement of the workshop responsible for the sulfur dyeing process, this might be the last chance to own a piece made from this unique black Secret Denim—a true collector's item. This coverall is not just workwear, but a versatile, enduring wardrobe essential.
Fit Notes: Despite being a Japanese jacket, like most ONI garments, we find the sizing of this Type III to be more Western than Japanese. If you usually wear a size M in American jackets, you'll find a suitable fit with this jacket in size 40 (M). However, as always, we recommend consulting our size chart for the perfect fit. The fabric is unsanforized but the jacket has been one-washed to reduce most shrinkage.
