Delivering refined styling with maximized performance, this is the ideal twin-lens mask for skin and scuba divers.Equipped with UV420 lenses and a skirt uniquely designed for increased comfort. MANTIS LV’s exclusive lens shape, low-volume construction, and optimized inclination angle allow for an extended field of view.
Protecting the eyes from UV rays (up to 400nm), as well as HEV light (400-420nm) that contribute to oxidative stress and deterioration.

*Due to the UV coating, the lenses in the photos appear to be pink, but are actually aqua-tinted.
The UV420 CUT lens is able to block harmful HEV (high-energy visible light in the 400 to 420 nm spectrum) which causes oxidative stress and deterioration of *lutein in your eye. Lutein is said to act as natural sunglasses. It is present as a pigment in the retina, a crucial part of the eye that receives light and allows you to see. The UV420 lens prevents cumulative macular degeneration by blocking harmful light and has an anti-oxidant effect. Lutein is destroyed when it absorbs harmful light. Its presence in the retina is limited and, because the body cannot make lutein, it can only be replaced by eating lutein-rich food.
Light tends to cause oxidative stress and lutein (pigment) deterioration.

Protection of lutein reduces oxidative stress, resulting in less pigment deterioration.

Inherits the form of the Mantis, but with reduced mask volume and even wider up‒down and L‒R arcs of vision. Wherever you dive, see across a wider field of view.
*Measured using Gull standard procedures.
The inclination angle and shape of the lens work together to extend the downward field of vision. You can see better through the arc down to chest level, which is where most diving tasks are carried out.
