The M3001 Freedom Tri-Quest Mask features TUSA's Freedom Technology with newly designed patented domed side windows and an expanded panoramic view through a 1-window lens. The Tri-Quest Mask has a reduced frame structure to reduce blind spots and a three-dimensional strap for an unprecedented fit. 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.

Mask skirt has a double feathered edge design. 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. The Skirt edge and 3-D strap combined for a perfect fit on the face. 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.

Crystal-View 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 Crystal-View lenses transmit 92% of available light to the diver for clear crisp vision. 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. Mask has an easy to reach one-hand nose pocket for ear equalization. Mask comes with a protective mask box.
