As much a jacket as it is a heavy shirt, this updated Filson® Men's Mackinaw Wool Flannel-LIned Jac-Shirt is warm, weather-resistant, and highly 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 Filson® re-imagined that iconic classic, creating their beefiest jac-shirt with an entirely 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 on end. Only the longest and strongest fleece fibers are selected for their Mackinaw Wool, which are 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 their signature Alaskan Guide Flannel that’s been a favorite of bush pilots, sportsmen, and tradesmen for decades.

The flannel-lined, angled-entry hand pockets 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 absolutely reliable and easy to operate even with gloves on. 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. The updated Lined Mackinaw Wool Jac-Shirt–the simplicity of a shirt with the weather-resistant warmth and breathability that only Mackinaw Wool can provide.
