Derived from Mantis LV, Mantis LV-R (Reloaded) incorporates a smaller overall form, added features and refined styling accents.Exclusively equipped with UV420 AR lenses, and Gull’s brand new Comfort-Fit Technology silicone body, Mantis LV-R truly is much more than a size scaledown.


Protects eyes from UV rays (up to 400nm), and HEV l ight (400-420nm), that contribute to oxidative stress and deterioration of lutein*. AR (Anti-Reflective) feature improves light transmittance for better visibility.

Comfort-Fit Technology(PAT. P)

Reinforced Damper

Facial movements may compromise a mask’s seal causing flooding around the lips. Reinforced dampers keep the skirt’s edges securely in place preventing flooding even with substantial facial movements.

3D Leak Guard

Faces tend to crease around nose and mouth (laugh lines), and do even more so when clenching a snorkel or regulator. The skirt’s inner three-dimensional surface is specififically engineered to maintain a locked seal at the laugh lines.

Temple Line

The skirt’s trim is augmented to avoid the hairline near the temples to further prevent chances of flooding.

Easy-Pinch Nose Pocket

Construction of the nose pocket and surrounding area is altered making it much easier to pinch the nose for improved equalization. Gaps between nose and frame are widened allowing for an easy pinch even when wearing thicker gloves.

UV420 CUT AR Lens

UV420 CUT AR Lens

Protects eyes from UV rays (up to 400nm), and HEV l ight (400-420nm), that contribute to oxidative stress and deterioration of lutein. AR (Anti-Reflective) feature improves light transmittance for better visibility.

UV420 CUT Protection

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.

Lighting can alter the appearance of a tunnel. Orange light make objects more visible by increasing the contrast of its shadowed edges. White light increases overall visibility by generally illuminating everything brighter. As in the orange-lit tunnel, our previous UV400 Amber lens increases contrast, while the UV420 CUT lens provides a brighter visual such as with white LED light.

Eye Behind an Ordinary Lens

Light tends to cause oxidative stress and lutein (pigment) deterioration.

Eye Behind a UV420 CUT Lens

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

Low Volume

Volume: 110cc Weight: 215g*
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.

Size & Field of View

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.
