03501-SHVCH - 13oz "Super Heavy Chambray" Denim Jacket - Coverall

ONI
$ 275.00

Oni Denim pushes the boundaries of chambray with this 13oz super heavy coverall, overturning the fabric’s traditional concept by achieving a thickness comparable to denim. While the weight brings a crisp, structured feel, it still retains the natural lightness and breathability that defines chambray. The design remains pared down and functional, with a sharp silhouette that feels clean and modern. Small workwear-inspired touches, like three-fold cuffs reminiscent of early 20th century jeans hems, ground the piece in Oni’s heritage-driven detail work.

  • 13oz super heavy chambray (100% cotton)
  • One-washed for softness and ease of wear
  • Structured hand with chambray’s natural lightness
  • Clean and simple coverall design with sharp silhouette
  • Three-fold cuffs inspired by early 20th century workwear
  • Oni Denim original donut buttons
  • Made in Japan

Fit Notes: Shop owner Tommy is wearing a size 42 in this jacket. He's used to wearing a 42 in these jackets across the board. This jacket was a pleasantly boxy cut. The coverall is meant to fit with a roomier body and longer torso, but you can totally make it more tailored if you prefer. We would recommend sizing up just once on this if you don't know your size, or buying your standard ONI size if you do. Tommy is 5'10," 162lbs, with a 40" chest.
