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.

TUSA?s revolutionary 3D Mask Strap fits snugly fits against the head?s curvature for superior comfort fit and unprecedented fit.

Anti-Reflective (A/R) Lens Treatment

Standard glass lenses can reflect up to 15% of available light reducing vision underwater. 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.

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.

Quick-Adjust Buckle System

The 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.

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.

Conventional Skirt

The TUSA mask features a round mold, special cross-section-ally shaped skirt fitting line (the outer end part of the silicone skirt touching the face) and molded by rolling the edge to the outside. When the skirt portion of the mask touches the face, the conventional mask is fitted with thin edge lines (Fig. 1)

TUSA's Round Edge Skirt

Whereas with the TUSA mask, a round-edge skirt is fitted on the face (Fig. 2), resulting in a soft-fit suppressing pressure and reducing creasing left on the face. This ?planar fit, instead of linear fit? silicone skirt maintains a great seal and unprecedented comfort.

UV Lens Treatment

Increased exposure to UV light can damage the eyes especially in marine environments where reflectivity is high. TUSA?s UV Lens Treatment provides 100% protection from harmful UVA and UVB rays. Blocking 100% of the ultraviolet spectrum (under 400nm) provides greater eye protection without sacrificing light transmission or vision.
