Add to Cart:



We present you the world most complete range of snorkeling full-face masks.
Patented and EN136 / EN250 tested, to grant you the highest safety and the most fun!




Unica is the full-face snorkeling mask designed and manufactured by SEAC.

It allows you to explore the world below the water’s surface, breathing naturally through your nose and mouth. Exhaled air is vented through an exclusive patented system located in the front of the mask to make exhaling effortless and eliminate the noise that purge valves make. A separated channeling system for inhaled and exhaled air prevents the lens from fogging.
The snorkel features a Dry Top to prevent water from entering the tube. Full-spectrum view, with a 180° field of vision. The liquid silicone skirt and polycarbonate frame and lens offer enormous comfort.

A comfortable and flexible retaining strap holds the full-face mask to your head. An efficient water purging system uses a dump valve in the lower part of the skirt.






The best-selling and most-loved full-face mask:
7 colors and 3 sizes (L/XL adult - S/M adult - JUNIOR +6 years)
Adjustable strap in flexible fabric - Skirt in silicone

Available in the L/XL adult version and S/M designed for narrower faces (+10) and Unica Junior for children (+6).




...Let's have a chat about SAFETY

A feeling of fatigue and a build-up of CO2 in the respiratory system can lead to potentially serious consequences, even during low-impact physical activities like snorkeling. That’s why SEAC abides by two fundamental principles in designing its full-face snorkeling masks:
the user should need to employ the least possible breathing effortcomparable to natural breathing, out of the water and in a relaxing situation;
and the level of residual carbon dioxide CO2 inside the skirt while inhaling must be well below the safety limits.


Even though there is no specific European regulation governing the manufacture of full-face snorkeling masks, SEAC® has developed a series of specific tests that comply with the values set forth by the following European regulations:
EN 1972:2015 establishes the requirements for the design and manufacture of snorkel tubes, limited to breathing effort;
EN 16805:2015 establishes the requirements for the design and manufacture of dive masks;
EN 136:2000 establishes the minimum requirements for the manufacture of full-face respiratory protection masks, limited to tests checking the CO2 in inhaled air;
EN 250:2014 regarding open-circuit compressed-air self-contained breathing apparatus and its components, limited to tests checking the CO2 in inhaled air.

In the SEAC labs, batches of full-face masks are tested with Ansti machines, specifically to measure the dynamic performance of human breathing, and with proprietary SEAC equipment to check levels of CO2 in the air inhaled through the masks. All this makes it possible for us to offer the end user the best possible snorkeling experience, in complete safety, because with SEAC® full-face masks, having fun is as natural as breathing!
