The Cressi Nano Mask is one of the most popular masks for freediving and spearfishing. It is designed to offer an extremely hydrodynamic and compact shape to help divers cut through the water and aid movements in small spaces. The internal volume is minimal and does not require intentional equalizing.
The Nano enjoys a conglomerate of technical advantages that Cressi has been incorporating the last seasons in different models. It combines a great technicality with a captivating design and medium proportions, both of frame and face. Its frame of reduced thickness in a single piece, without fences, allows a great lightness (125 g) and a surprising approach of the glass to the eyes with the consequent advantages in terms of visibility and reduction of the internal volume. The mask assembly is radial (non-axial); the frame, divided into two parts that are joined by a clip, surrounds the glass as a clamp. This system improves the sealing of the mask, eliminates any possibility of uncomfortable contact between the frame and the forehead and eliminates any vision of the central area of the frame from the inside. Your facial optimizes dead spaces and reduces internal volume to only 85 cm³. The glass / face distance has been reduced to such an extent that the face does not make the known suction effect, it simply sits on the face providing an optimum seal thanks to its design and the studied relationship thickness / level of stiffness of the silicone. Inclined crystals that extend through soft curved lines above the cheekbones, improving lower visibility. The very thin frame and the studied coupling with the delicate area of the frontal bone optimize the superior visibility without harming the ability to adapt. The buckles, anchored in the frame for optimum stability of the mask and a tension always to be determined by the user, are completely foldable and tilting in all directions. Therefore the possibility of breakage is almost impossible. This type of anchoring also improves the stability of the mask, since the tension of the strip occurs on a rigid element and the movements of the tube do not affect the facial.
