TECHNOLOGY
 
3D SYNQ
TUSA has developed a unique Fitting Ring that has been built into the Mask Skirt. This technology enables the Mask Skirt to mold to all face shapes providing the ideal fit, seal and underwater experience. 
 
SWIFT BUCKLE 3D
TUSA has designed the perfect buckle and mask strap. The NEW low profile buckle is slim and light weight. The easy adjustment buckle and strap is silent and effortless when making adjustments.
 
FREEDOM TECHNOLOGY
Freedom Technology is a set of technologies to enhance fit and performance exclusive to TUSA. Freedom model masks feature a dimpled skirt surface with varied silicone thicknesses and stability ridges in addition to a proprietary low-friction skirt surface on the fitting line. 
 

3D MASK STRAP
TUSA’s patented 3D Strap is a true three-dimensional design that snugly fits against the head’s natural curvature. The 3D strap offers unprecedented comfort and fit, unlike standard flat mask straps. 

 
CRYSTALVIEW OPTICAL GLASS
CrystalView optical glass lenses provide superior clarity, color, and transmission of light over standard glass lenses used by the competition. Up to 15% of available light can be lost with a standard glass lens due to impurities and reflectivity. TUSA’s CrystalView lenses transmit up to 95% of available light to the diver for clear crisp vision.  CrystalView lenses are used in all PRO models masks. 
 
PANORAMIC VIEW
Panoramic View masks feature a variety of designs offering an incredibly wide field-of-view. Several designs incorporate minimum frame volumes, domed side-windows, reduced frame structures as well as three and four window styles for maximum vision.
 
ROUND EDGE SKIRT
TUSA's Round Edge Skirt features a proprietary round edge cross-sectionally shaped skirt. This rounded edge results in a soft fit that suppresses pressure and reduces creasing left on the face. The "planar fit, instead of linear fit" silicone skirt maintains great fit and unprecedented comfort.
