Airhole balaclavas for snowboarding and skiing, built around the hole. Your breath goes out through the Airhole instead of up into your goggles, so your lenses stay clearer and the mask doesn't turn clammy. Pick the original single hole or laser micro-airholes, then the fabric for the day, from lightweight Drytech to merino and Polartec® fleece. Most are hinged to sit flat under a helmet.
