The Airhole Airtube is a traditional shape neck tube, designed to keep you warm and dry while protecting you from the sun. Impeccably crafted, the airhole is designed to allow breath to escape freely, avoiding a build-up of condensation which will keep you dry, warm and your goggles fog free! Additionally, all Airhole masks have a minimum UPF of 50 delivering 98% protection from harmful UV rays. Great for the prevention of premature aging and the risk of damage to skin.
