Zensee Pro is Tusa's first frameless diving mask with all of their innovative features plus anti-reflective lens treatment, UV 420 lens treatment and their superior CrystalView optical lens. UV 420 Lens Treatment: Protects against harmful high-energy visible (HEV) light. UV 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. CrystalView Optical Lens: Provides 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.

Anti-Reflective (A/R) Lens Treatment: Anti-reflective coating enhances overall vision. Tusa'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. Anti-Fog Film: Durable, long-lasting material to greatly improve visibility by preventing mask fogging. 3D SYNQ: A unique fitting ring built into the mask skirt providing an ideal fit for all face shapes. This technology enables the mask skirt to mold to all face shapes providing the ideal fit, seal and underwater experience. Swift Buckle 3D: A new low-profile buckle and mask strap for smooth effortless adjustment. Tusa has designed the perfect buckle and mask strap. The low-profile buckle is slim and light weight. The easy adjustment buckle and strap is silent and effortless when making adjustments.

Freedom Technology/Freedom Dry: Enhances comfort and fit by utilizing a revolutionary low friction skirt surface. Each person has a unique facial structure and every diver experiences either some level of discomfort, or pressure and squeeze while wearing a typical mask underwater. Tusa engineers wanted to solve these problems and spent several years analyzing mask fit, facial bone structure and mouth movement. The result is Freedom Technology, a set of revolutionary new mask features which deliver superior fit, comfort and increased performance. Dimpled Skirt: Key areas around the forehead and cheek bones have been designed with dimples which combine to increase the skirt's softness, flexibility and skin surface contact. This also greatly reduces leakage and enhances comfort. Stability Ridges: As water pressure increases a mask will compress inwards toward the face often causing further leakage. Areas under the cheek bones have been reinforced with stability ridges to minimize this compression maintaining ideal skin surface contact. Varied Silicone Thickness: When in usage, a regulator or snorkel mouthpiece can distort areas of the nose pocket and mouth section causing leakage and discomfort. Freedom Dry enhances comfort and fit by utilizing a revolutionary low friction skirt surface. The skirt fitting line features a low friction surface that delivers a superior seal and increases the facial area contact patch while significantly reducing excess skin tension. The result is a soft and supple feeling mask with a dramatically improved seal.

3D Mask Strap: Tusa's unique 3D design contours to the shape of your head. 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. Round Edge Skirt: Round edge skirt improves both seal and comfort of the mask. Panoramic View: Mask providing an extra wide field of 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.

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. The Tusa Zensee Pro Mask has all the standard features you would expect from the Tusa brand. Mask has a double feathered edge silicone mask skirt that works in concert with the wide 3D split strap for a perfect seal on the face. Mask has an easy to reach one hand nose pocket for ear equalization which can be utilized even when wearing thick gloves. The mask has a single tempered glass lens. The Zensee Pro Mask comes with a protective mask box and is available in multiple colors.
