Filson adapts its beloved Jac-Shirt design for even colder weather with fleece and twill lining.
Filson's original Jac-Shirt has been a cool-weather staple of their lineup for nearly five decades. Lined with the company's warm Alaskan Guide flannel in the torso and polyester twill in the sleeves, this version is even better suited to the cold. As before, the exterior is crafted from Filson's Mackinaw Wool, made using the longest and strongest fleece fibers spun into exceptionally dense yarns and woven into a weather-resistant tight weave. Angled-entry hand pockets are lined with fleece to keep hands warm, while snap closures secure the front placket, adjustable cuffs, and flap chest pockets.
