A classic wardrobe staple built with our iconic heavy wool. This jacket combines the styling of a classic blazer with the warmth and weather protection that’s made our Mackinaw Wool a trusted fabric in the field for more than a century. With its nautical roots tracing back to the 1800s, our blazer features a 3-button front closure and notched lapels. The torso is unlined, and the sleeves feature a slick twill lining easy for easy on/off over shirt sleeves. Our Mackinaw Wool is a very tightly-woven twill that turns away chilly winds, is quite water-resistant, and provides decades of service. All-natural wool features a uniquely complex fiber structure that allows it to continue insulating even when wet. The Mackinaw Wool Blazer – a timeless classic.
