Hollis M1 Mask – not only mask this is TOP Mask
The Hollis M1 Mask provides every thing that you could want in a diving mask, ultra low profile design, super soft superior quality silicone skirt, frameless construction for improved field of vision and reduced weight and optical grade glass for improved clarity and light transmittance.
Saint-Gobian Diamant Crystal Clear Glass that has a significantly lower iron content than standard glass. This reduction in iron removes the green tint that is often apparent in cheaper glass and allows more light to filter through the glass without being reflected back out by the impurities. Colour distortion is also reduced, giving true colour representation.
