About this product
A full-face snorkel mask replaces the mask-plus-mouthpiece arrangement with a single unit covering the whole face. You breathe through your nose and mouth exactly as you do on land. For a large number of people – children old enough to be trusted with it, nervous first-timers, anyone who has tried a mouthpiece and hated it – this is the difference between snorkelling and not snorkelling.
Fogging is the thing every full-face mask has to solve, and it is solved with separated channels. Air comes in down one side of the snorkel and passes across the inside of the lens before it reaches your nose – which both keeps the glass clear and means you never re-breathe your own exhaled air. The breath you push out leaves by a different route entirely. A single-channel full-face mask fogs within minutes and leaves you breathing stale air, which is why the design detail matters.
The dry top is a float in the head of the snorkel. Under a wave or a duck of the head it rises and seals the opening; when the top clears, it drops and you breathe normally. There is also a drain at the chin for anything that does get past the face seal.
Use it on the surface. A full-face mask is not built for diving down – you cannot equalise the whole air space properly against pressure, and you cannot clear it underwater the way you can a conventional mask. Swim face down on the surface, look at the reef below, and if you want to dive to it, take a separate mask and snorkel.
Fit is the other rule. A full-face mask only works if the skirt seals all the way around, so check the size against your face, keep hair out from under the rim, and be aware that a full beard along the jaw will break the seal.
