The Anderson Shirtjac is back. If you’re staring down a forecast that looks a little unpredictable, you can rely on a shirtjac for all your proper layering needs. A relaxed fit, designed with extra room for layering. Soft brushed flannel exterior, with an insulated quilted interior. Two chest pockets with button closure and a custom bison snap on the bottom placket, hand pockets, and finished with our MK icon embroidery on the back yoke.
