Barbour Marlow Tailored OvershirtA quality overshirt should be in every man's fall wardrobe rotation, and this option from Barbour is a solid one. It's made from a polyester wool blend, with a button through front closure and tartan trim inside the collar. Two chest patch pockets provide utility, while the side welt pockets keep hands warm. Finished with a subtle Barbour flag on the left seam.
