Description
The Outdoor Research Alpine Onset Merino 150 Beanie is a lightweight, low-profile merino wool blend beanie designed for active use in cold conditions. Its breathable, moisture-wicking construction provides comfortable warmth while naturally resisting odours, making it well suited for extended wear during high-output activities.
Designed to fit comfortably on its own or beneath a helmet or hood, the close-to-head profile minimizes bulk while a double-layered earband provides additional warmth around the ears and forehead. UPF protection adds versatility for exposed alpine environments, making the Alpine Onset an adaptable option for skiing, climbing, trail running, and other cold-weather activities.
