Our Mackinaw Wool Vest provides warmth with excellent breathability, even when wet. Worn over a flannel shirt or under a coat, it adds warmth for comfort in the cold. Mackinaw is our iconic wool that's provided protection from cold and wet conditions for over a century. Manufactured with an uncommonly tight weave, our signature excels at blocking the wind and withstands hard use for decades. This vest's design works just as well indoors, whether drawing up plans for your next big project or working in a chilly warehouse. The V-shaped neckline adds no bulk around the neck, so there's still plenty of breathing room for a heavy shirt and a rain shell zipped chin-high. The front features open and slotted chest pockets plus side-entry hand pockets.
