The mask frame is made from three materials to make it both lightweight and durable. 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.
TUSA's 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 with UV/AR treatment transmit up to 95% of available light to the diver for clear, crisp vision.
The Paragon Mask has a double feathered edge skirt and a wide split strap design that work in concert for a perfect fit and seal on the face. The dual tempered lens revers teardrop design provides a wide field of vision in all directions. Mask as a large easy to reach nose pocket for ear equalization that is accessible even when wearing thick gloves.
I love this mask. The quality of the glass is very impressive. Just like wearing a pair of Costa sunglasses underwater. No glare and a very clear image forward. This mask fits me very well and I enjoy using it when I dive for fun or teaching.
