Cotton twill overshirt / light jacket from American outdoorswear pioneers Filson, featuring button closure, chest pockets and handwarmer pockets in a traditional rustic plaid design. Excellent over-layer in warmer weather, to guard against the spring-summer evening chills, or perfect as a midlayer in wetter or colder weather, the Deer Island Jac-Shirt is truly designed with hybridised and flexible wearing in mind. The side hem vents allow an easy and full range of motion, meaning you can walk, garden and get about easily and comfortably in it, without skimping on style and cut. The cotton is thick, lush and soft, meaning it's like slipping on a trusty old companion every time you wear it. A great all-rounder that you'll be thankful for in changeable weather, and easy to bundle up and travel with too.
