Introduced by Filson some fifty years ago, the Jac-Shirt serves as a heavy shirt, overshirt, insulating layer, or light jacket.  Sewn in Filson's Washington factory, their original Jac-Shirt is an outdoor staple that provides warmth in all conditions like only 100% wool can.  The 18-oz. fabric is crafted with a tight weave that delivers an optimum balance of breathability and wind resistance, while providing durability for decades of service.  Wool has a complex fiber structure that makes it naturally water-resistant, moisture-wicking and warm even if it gets wet.  Wool also resists odors, making care and maintenance a simple affair. Despite science's best efforts, to date no man-made material can provide the all-around performance of nature’s original miracle-fiber.  It's nature's technical material.  The Jac-Shirt has a straight hem for untucked wear.  Being designed active use, it's cut with room to move without binding when worn over a shirt or heavy base layers.  The two chest pockets feature buttons that are hidden under the flaps.
