Tusa Freedom Quad Dive Maskfeatures the newly developed and revolutionary Freedom Technology delivering superior fit, comfort and performance. The Freedom Quad fitline, lens and frame shape are derived from the popular Freedom One with added features of CrystalView Glass and Panoramic View.
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 a set of revolutionary new mask features delivering superior fit, comfort and increased performance.
