When the temperature drops and lighter layers stop cutting it, the Core Merino 330 Bottom delivers the heavyweight warmth you need to stay comfortable in serious cold. Built as a high-performance base layer for very cold conditions, it combines the natural benefits of merino wool with moisture-managing comfort that helps you stay dry through long days outdoors.
The 330 Series is made for frigid weather and cold-weather activity, giving you more warmth with less bulk so you can layer easily without feeling restricted. The 330-gram, 17.5-micron ArmorSpun Merino Wool exterior is lightweight, durable, and naturally odor resistant, while the recycled synthetic lining moves moisture away from your skin to help keep you dry and warm. It also adds anti-itch comfort, making this a dependable next-to-skin layer for late-season hunts, range days, and all-day outdoor wear when conditions turn harsh.
