Technical 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. If 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).
0% PVC
This mask and snorkel set contains no PVC.

Used for 2 to 8 weeks
Love Decathlon, but was disappointed this time, bought 3 of these to take to Cuba, my daughter used one, wasn't too bad to start , but made her face very sore and then leaked a lot, my husband had a go with the other two, but found they didn't seal around face so leaked badly, so gave up with them. Complete waste of money, which we left in Cuba. Would have been furious as it would have spoiled our holiday as we snorkelled everyday, but for the fact we also had easy breathe mask which was fantastic. Wish we had saved the £30+ we spent on these and bought another easy breathe mask!
All of it
