The Nano is for advanced divers, freediving and spearfishing lovers, designed to offer an extremely hydrodynamic and compact shape to help divers cut through the water and aid movements in small spaces. For develop the Nano mask Cressi invented and patented the Integrated Dual Frame Technology System. The IDF Technology consists of the joining of two rigid frames, the first on the rear of the silicone skirt and the second, anterior to the first one, that support the lenses. When the two frames are joined and locked together, the silicone skirt remains locked in the middle to guarantee a perfect seal between the face piece and the lens. This technology produces a drastic reduction in the internal volume, while keeping the lenses close to the eyes to ensure a wide view laterally and in the lower zone. The result is a mask with an extremely hydrodynamic shape and low volume. It is the mask on the market with the lowest internal volume (12.86 in2 | 83 cm2), an ideal requirement for freediving lovers. The completely flexible, virtually indestructible buckle is a Cressi patented sytem (US 8281471 B2). It does not require intentional equalizing. The swiveling buckles feature micrometric regulation. Mask features inclined and inverted tear-drop lenses for improve downward visibility, a Cressi’s patented design (US 6272693). An anatomical strap ensure a perfect seal on the head. The Cressi mask is designed and made in Italy by Cressi, brand pioneer in Scuba Diving, Snorkeling and Swimming equipment.
