We beefed up one of our most iconic, versatile garments by manufacturing it with our warmest 26-oz. Mackinaw Wool and added a warm flannel lining and hand pockets to create this special-edition Mackinaw Jac-Shirt. Wears like a shirt, insulates like a warm coat, and available this season only in this striking new color. 

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. Our Mackinaw Wool, from Oregon’s famed Pendleton Woolen Mills, is sourced from hardy sheep raised in the Pacific Northwest 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, side-seam 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 boasts a slotted utility pocket, perfect for stowing pens or small tools. The sleeves are lined in polyester twill, for ease of layering. 

The limited-edition Mackinaw Jac-Shirt¬–the simplicity of a shirt with the weather-resistant warmth and breathability that only our Mackinaw wool can provide.
