SKU: 20232893 Filson Men's Lined Mackinaw Wool Jac-shirt

A warm, fully-lined wool jac-shirt with a snap-closure front.

As much a jacket as it is a heavy shirt, this updated Mackinaw Wool Jac-Shirt is warm, weather-resistant, and highly breathable.

Our 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 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 our 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 our 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.

Our updated Lined Mackinaw Wool Jac-Shirt–the simplicity of a shirt with the weather-resistant warmth and breathability that only Mackinaw wool can provide.

Relaxed fit allows room for midweight layers underneath
