The Filson Vintage Flannel Workshirt has been a favorite of Filson employees and customers alike since its 2015 introduction, though its classic style makes it appear it was introduced decades earlier! Built with thick and breathable cotton flannel, it’s ideal for cold weather. The fabric is heavily brushed for outstanding softness and thermal retention. Dual shoulder pleats on the back yoke provide unrestricted range of motion for working overhead, casting a fly rod, or shouldering a shotgun. Virtually unbreakable buttons are used for the front closure and adjustable cuffs to ensure long-term durable service. Proudly offered by Jesse Brown's Outdoors.
