Blurring the line between rugged utility and refined everyday wear, this 12.5oz Coverall from ONI is a true workwear icon reimagined. Crafted in Japan and designed by the legendary Oishi-san, it captures the soul of vintage American workwear through a distinctly Japanese lens, offering durability, functionality, and subtle sophistication in equal measure.

At the heart of this piece lies its unique 12.5oz low-tension selvedge denim woven on vintage shuttle looms. The distinctive color profile combines black sulfur-dyed warp with olive sulfur-dyed weft, creating a rich depth that will evolve into a unique patina with wear – similar to traditional indigo but with an entirely different character. A vibrant pink selvedge ID provides striking contrast against the dark fabric.

Thanks to its low-tension weave and Tempi (one-wash) treatment, the fabric feels surprisingly soft and broken-in right out of the box, making it an ideal transitional jacket for fall and beyond.

Designed with purpose, the coverall features four practical pockets—two lower handwarmers, one exterior chest pocket, and one interior breast pocket—offering modern functionality without sacrificing style. Copper buttons and rivets round out the garment with ONI's signature premium details.

Whether layered over a tee or a hoodie, this piece brings updated workwear versatility to your wardrobe with unmistakable Japanese craftsmanship.

Fit Notes: Despite being a Japanese jacket, like most ONI garments, we find the sizing of this coverall 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. It is unsanforized but bio-washed, so there will be no shrinkage.
