Jersey Flannel 908 Shirt Jacket (Size 3)

This working shirt jacket is designed for versatility, featuring four large patch pockets that make it as easy to wear as a shirt. Whether worn as a shirt or a coverall, it’s a practical piece you can take anywhere.

At 45R, autumn is synonymous with jersey flannel. While flannel is typically associated with wool, a formal fabric, we wanted to create something that maintains a polished look yet feels as relaxed as a jersey.

The result is a wool yarn spun for resilience, giving it a full, lofty texture that is thin, lightweight, and warmly insulating. The raw edges are finished like selvedge, offering an elegant, refined wear that embodies Japanese craftsmanship at its finest.
