Our Men's Merino Sport Ultralite Vest is purpose-built for comfort and convenience. It's made with strategically placed panels of Merino Sport Ultralite fabric to help regulate your temperature as your activity heats up, and its fit lets you move comfortably without extra bulk. Plus, it's designed with the elements in mind: its nylon outer shell can offer added protection from wind and moisture. And because it neatly packs into its own right-hand pocket, this vest is easy to bring along on your next out-of-town adventure.
