When it comes to manufacturing masks, Cressi use 'crystal silicone' for their mask skirts.
This exclusive Cressi material is rather lovely - it makes the skirt virtually invisible when diving.
Cressi build beautiful masks so I expect great things from their latest offering: the "Air Crystal". The parent of this 'top of the range mask' is the highly popular Nano-mask. You can see it when you look at the tapered structure of the Air Crystal.
Small tweaks make a big difference - the skirt sides have added ridges to help increase the structure of the mask whilst enhancing how the mask seals on the face. According to Cressi this dual-lens framed mask has a hydrodynamic shape therefore the diver benefits from a wide and lateral field of vision.
