The Cressi Big Eyes Evolution Crystal Mask is made from Crystal Clear Hypoallergenic High Seal Soft Silicone Rubber, a new material that offers extraordinary and unprecedented comfort and fit. The mask rests on the face with this unprecedented silicone rubber and does not leave any marks on the skin, even after extended use. So if you're tired of your mask gives you ring-around the eyeballs, this mask is for you. Naturally, to obtain such a result the entire structure of the skirt is differentiated, with internal ribs that stiffen the parts of the mask that are most stressed.

* Mask is slightly discoloured due to age but this does not effect the quality or performance.
