The Matrix is a design that started with a detailed image of the bark of an old tree on the Pacific Crest trail. This new Beanie Hat is soft, lightweight, and warm for those chilly or cold days all year long. Keep cozy for all your outdoor activities or stay warm in a cold house or cabin. It's a perfect travel companion, tucks easily into a pocket, and weights only 1.2 ounces. With a little lift at the crown, you find it's not only functional, but stylish, too. Take it along wherever you go!
