A super-wide oval lens for maximum view that also gives maximum exposure of the face for photos. A special skindiving oval mask: smaller volume than the classic oval for easier equalization, luxe silicone, and the same large oval profile. The Oval Nano is the same mask with embedded antifog (it carries the NANO sticker on the lens); colors and fit are identical.
Super-wide oval lens - maximum view, reduced peripheral distortion.
Maximum face exposure - the mask for photos, models and photographers.
Smaller volume than a classic oval - easier equalization, easier clearing, better hydrodynamics.
