Water can enter the snorkel during your snorkeling sessions (surface splashes, immersion). The valve located at the bottom of the snorkel makes it easier to expel water. Most of the water is drained from the bottom, which means the user does not have to blow out so hard (unlike a conventional snorkel where the water is drained from the top).

How to use the valve

Simply blow out gently to empty the snorkel through the valve. After breathing out, be careful when you breathe in. Breathe in slowly, because there may be some residual water in the snorkel. When in doubt, do not panic: raise your head out of the water and the snorkel will empty itself instantly through the valve. High-speed intensive swimming is not recommended as it can move the valve and cause water to enter.

Valve maintenance

Sand or salt may become jammed between the valve and the hard part of the snorkel. This prevents the valve from lying flat: in this case, it is no longer watertight. In this case, simply rinse the snorkel thoroughly with clean water and check that the valve lays flat.

Snorkel tube

The size and volume of the snorkel are adapted to adult breathing.


Silicone is an extremely flexible and hypoallergenic material. The silicone mouthpiece provides increased mouth comfort.

0% PVC

This product contains no PVC.


The part of the snorkel that is placed in the mouth. Its specially designed shape makes it one of the most comfortable snorkels for your mouth.

Wave guard

The tube at the top of the snorkel is curved to prevent water from entering the snorkel. In this way, it limits water entry through the top of the snorkel.
