Ideal para mujeres que quieren ir a juego.

Es un color bonito, las gafas se empañan como todas ya valgan 100 euros aunque con técnicas de buceo no sucede jejeje... Muy buena idea el agujero para meter el tubo aunque queda demasiado recto.

tubo de respiración

El tubo de respiración muy mal la válvula se llenaba de agua muy rápido y no salida toda el agua al expulsar el aire. Al final use el tubo tradicional.

When freediving, water can enter the snorkel due to immersion or splashing. The valve located at the bottom of the snorkel makes it easier to expel water. Because of the valve, most of the water is drained from the bottom, which means the user does not have to blow out so hard. This is 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 correctly 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.

Snorkel tube

The size and volume of the snorkel are suitable for an adult's breathing.

Wave guard

The deflector is the part located at the top of the snorkel. Its curved shape creates a protection limiting the inflow of water through the top of the snorkel.


Size M is designed for thin faces and the size L covers wider faces.


Silicone is an extremely flexible 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 2 to 5 times more durable than traditional glass. If it shatters, it breaks into small pieces, reducing the risk of a major accident.


Mask certified compliant with safety requirements according to European EN 16805 standards: 2015. Certified by the INPP (French professional diving institute).


This mask and snorkel set contains no PVC.
