Jersey Flannel Shirt Jacket

The single-breasted shirt jacket with three buttons is perfect for both casual wear and formal occasions—just throw it on, and you're ready to go. It resists wrinkles, making it ideal for outings.

When we think of 45R's autumn collection, our Japanese-crafted jersey flannel immediately comes to mind—a material that truly represents the best of wool. Though it’s a formal fabric, we wanted to create something that maintains a polished appearance while offering the relaxed comfort of jersey.

The flannel is crafted from resilient wool yarn, knitted with extra volume for a soft, warm feel. The raw edges are finished like selvedge, resulting in an elegant, refined garment that highlights the meticulous craftsmanship of 45R.
