The Airhole Airtube Cinch Resort Facemask repels moisture and has a DWR (Durable Water Repellent) coating to bead water and prevent the fabric from becoming saturated to keep your face dry and comfortable making it ideal for all occasions as well as keeping your face safe from sunburn. The Airhole is standard on all their masks and is designed to allow breath to escape freely, avoiding the build-up of condensation to keep you dry, warm and your goggles fog free.
