Seaview 180 V3 Full Face Snorkel Mask
Full-face mask — the mask we swim with at Double Fathom
The Seaview 180 V3 is the full-face mask our travelers actually use, and the reason is simple: it changes how breathing feels underwater. Because the mask covers your whole face, you breathe naturally through your nose and mouth — the way you do on land — instead of clamping down on a mouthpiece. For first-timers who find that mouthpiece uncomfortable, or for anyone who wants to actually relax on a long float over a reef, that difference is the whole ballgame.
The 180° panoramic view is the second reason. A full-face design puts the lens across your entire field of vision, so the reef doesn’t sit in a frame — it surrounds you. FlowTech airflow keeps air moving through the chamber, the built-in GoPro mount means your footage lines up with what you’re actually seeing, and the mask comes in three sizes so the fit can be right rather than close enough.
One honest note we make on the gear hub and repeat here: full-face masks aren’t for young children. We recommend a minimum body weight of 25–30 kg, and an adult should always be close by. In March 2026 the US Consumer Product Safety Commission warned consumers to stop using OUSPT full-face snorkel masks after reports of labored breathing and loss of consciousness. That warning was brand-specific, but it’s a reminder of the basics: buy a reputable mask, check the fit, and never snorkel alone.
