Jersey Flannel 908 Sweat Pants

These sweatpants feature a stylish elastic waistband with a drawstring and belt loops placed at the center back, making them easy to pair with anything from a T-shirt to a jacket.

At 45R, autumn is synonymous with jersey flannel. Flannel is traditionally known as a formal wool fabric, but we wanted to create something that retains this polished appearance while offering the relaxed comfort of a jersey. This is where our dedication to Japanese craftsmanship truly shines.

We achieved this by spinning wool yarn for elasticity, resulting in a fabric that is thin, lightweight, and retains warmth. The raw edges are finished like selvedge, providing an elegant and refined wear that captures the essence of 45R's commitment to craftsmanship.
