ONI Denim 03502ZR "Secret Denim" 20oz Coverall


Many people associate workwear with high-quality construction and clothing that meshes very well stylistically. This ONI heavy Oxford Coverall Jacket certainly follows it to perfection.

Oishi-San is well known for interpreting American workwear staples through his Japanese dystopic lens. More of a character actor than a leading man, this heavyweight coverall will be the most reliable Autumn jacket in your arsenal. It's designed for work—with plenty of pockets and durable construction—and is understated enough to add some depth to everything from a hoodie to a tee. It has one inner and one outer breast pocket and two handwarmer pockets at the waist.

First launched in 2012, the Secret Denim has been one of the most desirable denim fabrics by Denim Heads around the world due to its unique texture and incredible softness and comfort. Only Oishi-San can produce this denim, and no one else can reproduce it. He uses extra-thick yarns of three different kinds of cotton woven at ultra-low tension on a vintage shuttle loom. The result is a beefier, extremely knotty unsanforized 20oz fabric with a fantastic slub, roughness and hairy texture.

The warp yarn is indigo rope-dyed. The weft yarn is beige dyed cotton. The fading potential is incredible and will showcase a variety of shades ranging over different tones of blue.

The coverall is made with superior-quality details such as copper buttons, a selvedge hanger loop and selvedge pockets.

Overall, this unique piece is a wardrobe essential for its durability and versatility.

The legend of ONI is alive to this day. In recent years Oishi-San has devoted himself to experimenting with widely varying grammages, rough textures, different indigo dyeing techniques and novelty cuts while always maintaining a very limited production and wielding his experience in denim which now goes back more than 60 years.
