See and breathe underwater as easily as you would on land The main obstacle to snorkelling is the difficulty in breathing underwater with a snorkel. Indeed, breathing through your mouth is unnatural, and the snorkel mouthpiece is sometimes considered too intrusive, uncomfortable and unhygienic. That's why Tribord invented the Easybreath, the first full-face snorkelling mask, for breathing underwater as easily and naturally as you would on land with your nose and mouth. Thanks to its large size, this innovative mask also offers users an unobstructed 180° field of vision, and is prevented from fogging up by a double air-flow system that is identical to the system used in domestic extraction fans.
