This classic shirt has earned its position at the core of Filson's business for very good reasons – it defines its genre and provides unfailing comfort and durability, season after season. The iconic flannel is brushed on both sides, adding a layer of softness and warmth that belies its thickness and weight. Ideal over a T-shirt in cool weather, or with a base layer and vest as the temperature drops. The dense, tight weave blocks chilly breezes, while adding a level of durability that’s unsurpassed. 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.
