What Our Gearhead® Experts Are Saying:“This baselayer is an absolute game-changer. It’s lightweight but keeps me warm on chilly dawn patrols and wicks moisture so I stay comfortable when the day heats up.”We reach for the Alpine Onset Merino 150 Hooded Baselayer Top by Outdoor Research as the foundation for cold-weather layering. Made with a premium blend of merino wool and recycled polyester, this baselayer is lightweight, naturally odor-resistant, and highly breathable—ideal for high-output activities in changing conditions. The hood offers extra warmth and fits snugly under helmets, making it perfect for early morning skin tracks or alpine climbs. Flatlock seams ensure chafe-free comfort, while the stretch fabric moves with us through every step, reach, and climb. Whether we’re on a multi-day backcountry tour or a brisk winter hike, the Alpine Onset Merino 150 delivers versatile performance we can depend on.
