Our iconic, breathable flannel shirt has a pleated back for freedom of movement. The original Alaskan Guide Shirt is the foundation of our flannel collection for good reason. It defines what a flannel shirt should be, providing comfort season after season. Our iconic flannel is brushed on both sides for softness and warmth. The tight weave blocks chilly winds while providing outstanding durability. It's ideal over a T-shirt in cool weather or with a base layer and vest as the temperature drops. The center-back box pleat provides ease of motion whether casting a fly, swinging an axe, or shouldering a shotgun.
