The Adirondack Overshirt from Owner Operator may just be the first garment you've ever bought that you can expect to wear for the rest of your life. This very warm and windproof shirt can be worn as a jacket or as a layering piece on very cold days. Wool is used to construct the original technical outerwear fabric. The wool naturally resists moisture and its hollow fibre core remains warm even when wet. It is blended with nylon which stabilizes the fabric, increasing abrasion resistance and improves water resistance. It is available in four colours namely dark forest, navy, red and chiller blue.
