A long day on the hill swings between working up heat and standing still, and the merino in the Eivy Hinge Merino Wool Balaclava regulates temperature and wicks moisture through both. The close-fitting shape sits low under a helmet and goggles, and a vertical front seam keeps pressure off the forehead. Wear it over the face for full coverage or slide it below the chin as the day changes. What Our Gearhead(R) Experts Are Saying:"The merino stayed soft against my cheeks and chin through full days on the hill. After several days in a row it still smelled fresh, since merino resists odor naturally."
