Airhole uses 3M medical grade Velcro ie the softest Velcro available on the market. 3M medical grade Velcro comes in thin flexible strips, which bend and twist with the fabric thereby maximising comfort for the wearer without compromising grip or adhesion. This Velcro is also has much finer ‘teeth’ so is snag free if you have long hair. If you snowboard or ski, choose an Airhole face mask because they all come with this medical grade Velcro.
