Filson's Alaskan Guide Flannel Shirt has been a mainstay trusted by bush pilots, sportsmen, ranchers, and tradesmen for over a quarter-century. Featuring brushed flannel on both sides of the fabric, adding a layer of softness and warmth that belies its thickness and weight. The pleated rear shoulders allow unrestricted ease of motion, whether you’re shouldering a shotgun, casting a fly or swinging an axe. Dual flapped chest pockets are gusset-expandable for bulkier items and secure with virtually unbreakable custom Filson buttons. Preshrunk. Proudly offered by Jesse Brown's Outdoors.
