3 types of high-performance lens

UV400 block Amber lensBlocks more than 98% of UV light (UV-A, UV-B, UV-C wavelengths). The tint can make visible objects stand out more clearly and the lens reduces the glare of visible light.
UV400 block Clear lensBlocks more than 98% of UV light (UV-A, UV-B, UV-C wavelengths). Faithfully transmitting colors, untinted glass provides a clear window on the underwater world. It is best for marine photography and other pursuits where the priority is color recognition.
Super Clear lensSee objects with greater clarity than with standard glass. Exceptionally free of impurities, the superior transparency of the glass lets you see objects more clearly. With clear silicone masks, the lens prevents reflections of the skirt on the lens.

Excellent UV blockingFitted with UV400 lenses, the mask stops more than 98% of UV light (UV-A, UV-B, UV-C wavelengths) reaching your eyes and skin. These high-performance lenses help you to more confidently enjoy diving.

Low volume

Volume:110cc weight:220g
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.

Inclination 10°

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.
