Filson Mackinaw Wool black sweater vest button front mens small pockets warm No size measures like a small 20” pit to pit 24” length The Filson Mackinaw Wool Vest, universally trusted by sportsmen, has proven itself to be as versatile, functional and practical as any product we’ve ever manufactured. This vest's all-conditions performance has made it cornerstone in the Filson product line for more than fifty years. This classic wool vest provides warmth with excellent breathability, even when wet. Worn over a warm shirt while active, it’s the perfect blend of warmth and breathability in temperatures down to near freezing. Under a Filson wool coat, it adds that extra bit of comfort in temperatures that can take your breath away. The design of the Mackinaw Wool Vest 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 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.
