Ryo and Hiro first hinted at this project over a year again while we were visiting them in Ichinomiya, Japan. The idea of OA working on leather jackets got us extremely excited, and we couldn't wait to see the results - and it has been well worth the wait.

These are based on the simple leather jackets of the early 20th century, which typically had a shawl collar, short button-up fronts, and side tab adjusters. They can be found with many options for pockets; OA chose slash pockets for utility.

Hand-distressed, custom-tanned Shinki horsehide makes up the body. The distressing gives the jacket a lived-in appearance right from day one, with plenty of room to add your own character over time.

True to size. These are intentionally short in the body, so check the size chart before ordering. As with everything from OA, the fit on these is perfect.

  • Custom tea-core horsehide
  • 100% cotton thread stitching
  • Corozo nut buttons
  • Slash pockets
  • Brass buckles
  • True to size
  • Cut by Ryo, sewn by Hiroko all in Ichinomiya, Japan
