With the cut of a shirt and the weight of a jacket, the Filson original wool Jac-Shirt has been an outdoor staple since the 1970s. This cotton variation is made with densely woven Bedford cord, a durable fabric with British roots. Densely woven with a notable vertical rib, it's been used for military uniforms and workwear for miners and railroad workers. The hem is straight for untucked wear. Chip resistant buttons secure the front and adjustable cuffs. Chest pockets are protected by buttoned flaps.
