Our mask is the generation 2.0 full face, focused on achieving the lowest level of CObuild-up possible, combined with both visual and technical innovation.

  • Transparent surfaces to clearly see the face

  • Ergonomic frame design with low visual-impact

  • Safe exchange and clearing of gasses, lowest COBuild-up

  • Large air-flow sections

  • Flat lenses combine to build a 3D shape, able to reduce optical distortion

    Our experience in the Diving and Snorkeling equipment market has led us to raise the standard of full face masks and create a product with unique features, both in terms of performance and safety.

    Sea Vu Dry + and Sea Vu Dry R + are at the forefront for comfort when breathing and in use. 


When breathing occurs within a closed volume, it can cause CO(carbon dioxide) build-up. 

Our Research and Development team studied dozens of prototypes, and conducted countless tests with our ANSTI machine, which allows us to measure the residual amounts of COat varying breathing intensity and frequency, in order to identify the best technical solutions.

Reference regulations are EU Standards EN250 and EN14143, widely used in the Scuba Diving industry. 

Test results:


VWA COat 10 l/min (Limit: 20 mbar)

VWA COat 62,5 l/min (Limit: 10 mbar)

12.62 mbar

Competitor D

MARES SEA VU DRY + is 14% below both limits, respectively -15% and -32% better than the nearest competitor product. 

These test results show that our superior full face mask offers incredible performance like no other! 



The fresh air enters through the snorkel’s central channel, passing the lens, keeping it fog-free. It then enters the oral-nasal pocket through non-return valves and flows towards the nose and mouth.


The oral-nasal pocket’s structure guides exhaled COthrough 4 no-return valves: • 2 no-return valves, one each side of the nose, to prevent backward flow,
• 2 no-return valves at the entrance of the exhalation tubes.


Exhaled COis channeled into the soft silicone side tubes through the second pair of no-return valves. Used air flows into the soft side tubes that are closed channels outside the mask, unlike the semi-closed channels used by main competitors.
Expiration progressively expels the used air, discharging COthrough the snorkel’s emptying channels.


The prismatic lense is a combination of 5 flat surfaces instead of 1. This feature, combined with very precise, rounded edges between the different surfaces, results in the lowest possible optical distortion and the best field of vision on the market, with an optical cone of 180° in all directions.


Measure the distance between the bridge at the top of your nose and the bottom of your chin.

Size S/M if the distance is between 10cm(3.9”) and11,5cm (4.5”) - Fits adults with thin faces, women and children over 10 years old.

Size L/XL if it is more than 11,5 cm (4.5”) - For an adult male, or larger faces. 

Once the mask is tight on your face, if there’s no space between your chin and the silicone skirt, you’ve got the right size. 

In 1949, Ludovico Mares designed and manufactured his first masks and spearguns with one dream and purpose in mind: To share his unbridled passion for the sea and diving with the rest of the world. 
At its birth, Mares was just one small factory in Rapallo, but now, only 60 years later, the Italian based company dominates the scuba diving world, and is at the forefront of new and innovative dive technologies. 
Over the past six decades, Mares has come a long way, by achieving new goals, taking diving to new and extreme heights and depths. The
Mares name represents only the best in dive products.

Guided by this principle, Mares has become a worldwide leader in the manufacturing and distribution of state-of-the-art diving equipment, and continually sets new industry standards. 
The constant investment in innovation, the unceasing, patient research in the field of manufacturing materials and processes, combined with the expertise of our staff and a creative, professional approach grants Mares its leading position and makes our brand a synonym of quality, safety and reliability. 
The best of Mares is wrapped up in every product to
meet the needs of each single diver. 
Enjoy diving with advanced performance through superior technology: this is our mission.

Discover all that Mares has to offer: you will find a collection of new fantastic products where superior technology and emotion is at the core.

But this result wouldn’t have been possible without our undisputed love for the sea, an all-encompassing vocation rooted in the history of our legendary founder that is felt powerfully by everyone at Mares. 
Although we manufacture our products using state-of-the-art machinery and use the most sophisticated electronic equipment, the core of our business and the spark that makes everything happen is still the same today as it was 60 years ago: Passion.
Come and discover the Mares world, all you need to do is...
Just add water.
