The most popular Airhole is the Standard 2 Layer Facemask, with its patented design that revolutionized the facemask, this is now a timeless classic. 2 Layer is a high performance, dual layer fabric designed for all conditions. The outer layer prevents icy winds from lowering your temperature whilst a water resistant layer protects from a wide range of conditions from wind to rain & sun to snow. Capable of protecting from light rain, average snow & light water pressure means these masks can handle all conditions. Finished with a soft lining, 2 Layer fabric is perfect for all day, all season shredding. The Standard 2 Layer masks features a silicone Airhole which is directly injected onto the fabric, bonding to the front & back to provide a comfortable, hygienic & easy to clean finish.
