This mask is specifically designed for free diving and it has been developed in cooperation with "MOMO design". Thanks to the production process adopted that allows to produce the mask in a single piece, the lenses are now much closer to the eyes compared to traditional masks. This allows for a reduction of more than 30% of the inner air volume. The field of vision is much wider, approaching to the natural field of view. The glasses of this mask are thinner (only 2 mm) and the overall weight of only 121gr makes it one of the lightest masks on the market. The masks also features great comfort and fitting.
