What Our Gearhead® Experts Are Saying:“This is one of those pieces I throw on nearly every day once the temps drop. It’s warm but breathable, thanks to that cozy sherpa lining, and the antique-finish snaps make it super easy to take on and off over layers. It’s basically the jacket version of a flannel—tough, comfy, and ready for anything.”When the leaves fall and the mornings turn crisp, we reach for the Carhartt Relaxed Fit Flannel Sherpa-Lined Shirt Jac. Built from heavyweight 8-ounce brushed cotton flannel and backed with a plush sherpa lining, this shirt jac delivers warmth with zero bulk. It’s the kind of piece that feels just as good chopping wood as it does grabbing coffee. Antique-finish snaps line the front for easy on-and-off, while triple-stitched seams and reinforced yoke pleats promise durability and freedom of movement. Whether you're tossing it over a thermal on cool days or layering under a coat when winter hits, this shirt jac works hard to keep us comfortable in all conditions.
