Hollis M1 Mask

The Hollis M1 mask has proven to be a bestseller over the years in the absolute top class of diving masks. The mask owes its reputation mainly to the lenses made of Saint-Gobain glass: ultra-transparent, extra clear and with unique optical qualities.

Thanks to the low iron content in the glass, the goggles provide a higher light transmission and a reduced green tint, which are typical of traditional diving goggles. This results in minimal color refraction and an extremely vivid and natural look, even in extremely poor lighting conditions underwater.
