This innovative Flowtech Snorkelling Mask for adults is the perfect piece of kit for your water adventures, such as snorkelling, swimming laps of a pool and exploring open water.

Dual Air Flow and Full Dry Top Technology enables you to breathe naturally through your nose and mouth while underwater.

Air flows in and out of the snorkelling mask through two separate tubes - one for inhalation and one for exhalation - ensuring fresh air with each breath. The unidirectional air flow also prevents the mask from fogging.

There’s a small flotation device that seals off the top of each tube so you can dive down, under the water, without fear of getting water into the breathing area.

High-quality silicone provides a comfortable, secure fit and the ability to equalise ear pressure. There is also an easy adjust buckle.

The snorkelling mask has a tinted lens to help filter out bright sunshine or lights. It is available in two sizes for adults: Small–Medium and Large–Extra Large. And the mask comes in its own full colour box.

Innovation is at the heart of this next generation snorkelling mask, and also at the heart of RNLI lifesaving. So whenever you wear your mask, you’ll be reminded that you’re helping the RNLI to continue innovating so that we can save every one who needs us.
