Introduced by Filson some fifty years ago, this icon has served more outdoorsmen in a wider range of conditions than we could begin to count. A heavy shirt, overshirt, insulating layer or light jacket, it performs without fail, no matter what role it serves. Sewn in Filson's Seattle factory, this original Jac-Shirt is an outdoor staple that provides warmth in all conditions like only 100% wool can. The 18-oz. Seattle wool is extra soft and is crafted with a tight weave that delivers an optimum balance of breathability and wind resistance, while providing durability for decades of service. The Jac-Shirt is a clean, simple design with a straight hem for untucked wear, but cut long enough that it can be tucked in to keep the wind out. Being engineered for work and active use, it’s roomy cut allows plenty of room to move without binding. The two chest pockets feature buttons that are hidden, so they don’t show with the pockets unbuttoned. The very last of the made at Filson in Seattle with Pendleton USA wool. The end of an era.
