Additional information

Water can enter the snorkel during your snorkelling 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 back in; inhale slowly as some residual water can remain 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
Sometimes sand or salt gets stuck between the valve and the hard part of the snorkel, this prevents the valve from lying flat and ensuring a watertight seal. In this case, simply rinse the snorkel thoroughly with clean water and check that the valve lays flat.
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.
The size and volume of the snorkel are adapted to adult breathing.
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.
Size M is for thin faces: 90 % of children over age 10, 90 % of women, 50 % of men. Size L covers wide faces: 50% of male faces and 10 % of female faces.
Flexible part of mask in contact with face.
Silicone is an extremely flexible and hypoallergenic material. A silicone skirt fits flexibly to the contours of the face, creating a watertight seal.The silicone mouthpiece provides increased mouth comfort.
Tempered glass lenses
Tempered glass is two to five times more durable than traditional glass. When it shatters, it breaks into small pieces, reducing the risk of a major accident.
Mask certified compliant with safety requirements according to European EN 250 standards. Certified by the INPP (French professional diving institute).

    Snorkel Set

    Very good value for money. This was used by myself and my 8 year old grandson on holiday and performed more than adequately; didn't leak or fog up.

    Snorkel and mask

    Bought a couple of these masks and snorkels for our annual holiday to Cornwall. Fantastic value and comes in a nice handy carry net to protect the glass from scratches. Worked wonderfully and keeps the little ones amused in the sea for hours. nice wide elasticated strap is easy to adjust and holds the mask comfortably but firmly on the head. Unlike the full face, more elaborate and expensive mask, this snorkel and mask (medium size) is not so sensitive to different head / face shapes and sizes and easily seals against both my face (40 something 6ft male, average build) and my 9 yr old daughter. the seal is effective and comfortable and the snorkel bite pad is also flexible, making it comfortable for extended use without destryoying your lips and gums.
    All in all fantastic value for money and highly recommended. Just be ready for the absolute terror when the kids realise they share the ocean with other living creatures!!!
