|TRI-MIX FrameThree (3) distinct layers combined to produce one superior frame structure. Polyurethane (PuRiMaX) material bumper protection and a cross-beam metal frame structure combined with the superior toughness of the polycarbonate frame bolted together to create a seriously tough mask.
|UV 420 Lens TreatmentUV 420 Lens Treatment protects against harmful high-energy visible (HEV) light and its potential to damage the Retina. HEV light is not just present on sunny days, but overcast days as well. Therefore, it is extremely important to protect your eyes against UV and HEV light in all weather conditions when diving.
|180 Buckle SystemThe buckle rotates a full 180 degrees to accommodate varying head sizes for optimum fit. The thin frame and rotation of the buckle allow the mask to be folded into a compact size.
|3D Mask StrapTUSA’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. Read more
|Angle Strap AdjustorThe Five (5) Angle Strap Adjustor allows for a five position micro-adjustment on both the left and right sides of the mask. This enables vertical (up/down) and horizontal (left/right) pressure on the face to be delicately adjusted for the optimum fit.
|Angle Strap Adjustor with Side HoldThe Skirt Mounted Five (5) Angle Strap Adjustor allows for a five position micro-adjustment on both the left and right sides of the mask. This enables vertical (up/down) and horizontal (left/right) pressure on the face to be delicately adjusted for the optimum fit.
|Anti-Reflective (A/R) Lens TreatmentTUSA’s Anti-Reflective (A/R) Lens Treatment decreases internal and external reflected light. This reduction increases light transmission to 95% resulting in significantly enhanced color, clarity, contrast and better overall vision underwater.
|Corrective LensCorrective Lenses are offered on several styles of masks. This option allows the diver to choose right and left lens powers in both a variety of diopters for maximum flexibility and for a custom fit.
|CrystalView Optical GlassCrystalView 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. Read more
|Hyperdry PurgeClearing a mask has never been easier thanks to our patented Hyperdry System. Simply breathe out through your nose and any water that has accumulated in your mask is forced out through a one-way purge valve. Once the mask is clear, the valve seals shut.
|Panoramic ViewPanoramic 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.
|Quick-Adjust Buckle SystemThe Quick-Adjust Buckle System incorporates a newly-designed low-profile buckle. The result is a compact, lightweight, technologically advanced mask design that can be easily and quickly adjusted for a perfect fit. Read more
|Round Edge SkirtTUSA’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. Read more
|UV Lens TreatmentTUSA’s UV Lens Treatment provides 100% protection from harmful UVA and UVB rays. Blocking of the ultraviolet spectrum (under 400nm) provides greater eye protection without sacrificing light transmission or vision.
