Wool jacket/overshirt with flannel lining and button closure from American pioneers Filson, featuring pleated back for full range of motion and handwarmer pockets. True blue American Workwear lumberjack chic, the Mac-Jac, as we like to call it, is made with 100% virgin Mackinaw wool, the warmest, softest stuff around, meaning the jacket us wonderfully soft and has a nice easy movement. It's been designed to really do stuff in, and it's pleated back allows comfort so you can really get to work/play outside. The super-soft insulating flannel lining is a beautiful touch, meaning you get the wool to brace the outside and the cosy, comfy flannel hug of the interior every time you put it on. Smart, durable, made to go and go, it's the perfect jacket to layer over a jumper and shirt and feel ready for the wild woods/streets.
