The new Tusa Freedom Ceos Dive and snorkel mask has an amazing field of view given that it is such a low volume mask.
The skirt is also one of the best we have seen: Thanks to the varied silicone thickness it is extremely thin where it needs to be but still robust enough to hold the shape. This feature allows the mask to provide a superior seal and fit while minimizing leakage.
Facial characteristics and shape are unique to every person and traditional masks can therefore cause discomfort underwater. TUSA engineers solved this problem after years of analyzing mask fit, facial bone structure and mouth movement. The result is Freedom Technology, a set of revolutionary new mask features delivering superior fit, comfort and increased performance.
