The innovative snorkeling mask enabling you to see and breathe underwater just like on dry land discovery of the underwater world becomes even more accessible. See and breathe underwater as easily as you would on land. The main obstacle to snorkeling is the difficulty in breathing underwater with a snorkel: Breathing through a traditional snorkel mouthpiece is intrusive, uncomfortable and unhygienic.
