A warm, fully-lined wool jac-shirt with a snap-closure front.
As much a jacket as a heavy shirt, this updated Mackinaw Wool Jac-Shirt is warm, weather-resistant, and breathable.
Filson’s original Jac-Shirt, introduced nearly 50 years ago and built with soft and warm wool, serves as a heavy shirt or a light jacket. It’s earned the enviable reputation for being the most versatile garment in a sportsman’s tool kit. In 2016 we re-imagined that iconic classic, creating our beefiest Jac-shirt with a new level of warmth and protection. Built with the same wool that’s sheltered foresters and sportsmen from wet and cold weather for over a century, our heaviest Jac-shirt is built to stand up to the elements for years. Only the longest and strongest fleece fibers are selected for our Mackinaw Wool, which is then spun into dense yarns and woven in an uncommonly-tight weave that turns away the weather and lasts for decades.
For even more warmth, it’s lined with Filson’s signature Alaskan Guide Flannel, a favorite of bush pilots, sportsmen, and tradesmen for decades. The flannel-lined, angled-entry hand pockets to warm your hands so you can maintain the dexterity to handle binoculars, shells, or tools. The snaps on the front closure, chest-pocket flaps, and adjustable cuffs are reliable and easy to operate, even with gloves. The left-chest pocket features a slotted utility pocket, perfect for stowing pens or small tools. The sleeves are lined in polyester twill for ease of layering.
Filson’s updated Lined Mackinaw Wool Jac-Shirt–the simplicity of a shirt with the weather-resistant warmth and breathability that only Mackinaw wool can provide.
