Why We Like The Mackinaw Jac Shirt
The Mackinaw, Filson’s heaviest Jac Shirt, keeps us warm while mucking stalls, sighting-in for grouse, and stringing holiday lights. Drizzles and flurries roll right off the woolly tight-weave construction, letting us continue our work despite nature’s resistance. The lined hand pockets give our fingers respite, keeping them nimble for their tasks, while the classic flannel look moves effortlessly from labor to leisure.
