Lightweight and breathable face mask and neck warmer made of merino wool. Never used. It has the unique scent of merino wool, but I think it will fade with washing. The Alpine Onset Merino Balaclava, which combines the natural odor-resistant properties of merino wool with the durability and moisture management of recycled polyester, is the perfect item for winter layering to prevent overheating. It can be worn alone or under a helmet in all winter scenes such as skiing, splitboarding, fat biking, and trail running. The OUTDOOR RESEARCH Alpine Onset Arbor Tube features a merino wool blend, UPF30 sun protection, breathability, moisture wicking, and a thin construction with natural odor resistance. - Brand: OUTDOOR RESEARCH - Model Name: Alpine Onset Merino 150 Arbor Tube, Balaclava Set. - Color: Black - Material: Merino Wool - Features: Lightweight and breathable Thank you for viewing.
