TUSA Freedom Quad Mask
The M-41 Freedom Quad is a low profile 4-window mask that features the revolutionary Freedom Technology delivering superior fit, comfort and performance. The Freedom Quad fitline, lens and frame shape are derived from the popular M-211 Freedom One. The M-41 comes standard with CrystalView Optical Glass lenses and is the first TUSA panoramic view model equipped with Freedom Technology.
In addition to Freedom Technology, the M-41 features TUSA’s patented Quick-Adjust Buckle System, 3-D Anatomical Strap, Round-Edge skirt technologies and is available in a black silicone.
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.
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.
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.
