Kotaro and Ian from Nine Lives design and craft garments unlike anything you've seen come out of Japanese craft manufacturing. The textiles and leathers used come from the best mills and tanneries in Japan; the factories and ateliers that cut and sew for them are the best in the world. Every step along the way is pushed further to produce something slightly feral, slightly out of step with the world.   

This is the double rider jacket you've always pictured in your mind, but have never seen before. It's a false memory made real. The fit is tailored. Everything unnecessary is gone. Everything that's left behind is upgraded. 

The base of the jacket is a 1.3mm steerhide combination tanned in Himeji, Japan. This tannage creates a leather that is soft and supple, yet retains enough stiffness and structure to mold to you over time. The best zippers YKK makes, the Excella, hold it shut and keep the cuffs from flapping. Front zipper is 2-way, of course, for ease of sitting and ease of looking good.

When we say tailored fit, this thing goes on like a bespoke suit jacket, and feels just as nice. The western yoke at the back combined with the trim fit and high armoles give it an aggressive stance without being in your face about. The jacket is fully lined in navy satin, including the sleeves.

These are Japanese-sized, and run quite small. You may have to go up two sizes.
