The shirt that’s earned a reputation as our four-wheel-drive flannel delivers comfort and situational range without altering flannel's tried-and-true function. Injected with a subtle Western ethic, its organic cotton is tough enough and warm enough to outlast long mountain winters. A roomy medium cut allows ample range of motion for splitting wood, and the burly 220-gram material holds up whether tuning skis in the shop or heading to town to let loose.
