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.
Each person has a unique facial structure and every diver can potentially experience some level of discomfort or "pressure" 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 delivering superior fit, comfort and increased performance. Experience Freedom.
Freedom Fit offers a superior fit and level of comfort by utilizing three specific design features.
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.
Varied Silicone Thickness: A regulator or snorkel mouthpiece, when in use, can cause areas of the mouth and nose section to distort causing leakage and discomfort. Varied thicknesses of silicone in these key areas reduce leakage and provide a better fit.
Stability Ridges: As water pressure increases, a mask will compress inwards toward the face often causing further leakage or discomfort. Areas under the cheek bones have been reinforced with stability ridges to minimize this compression maintaining ideal skin surface contact.
Freedom Dry enhances comfort and fit by utilizing a revolutionary low friction skirt surface. The skirt fitting line (shown in red) includes 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.

Freedom technology is a set of revolutionary features offering superior fit, comfort and increased performance in TUSA masks. 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.
CrystalView Optical Glass
CrystalView optical glass lenses provide superior clarity, colour 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 92% of available light to the diver for clear crisp vision. CrystalView lenses are used in all PRO models masks and also in the M-41 Freedom Quad.
TUSA's patented 3-D strap is a true three-dimensional design that snugly fits against the head's natural curvature. The 3-D strap offers unprecedented comfort and fit unlike standard flat mask straps.
Skirt Mounted Quick-Adjust Buckle System
The Quick-Adjust Buckle System incorporates a newly-designed low-profile buckle into the crystal silicone skirt of the mask. 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.
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.
