This Cressi Calibro Mask has a tapered structure deriving directly from the highly popular Nano-mask patent. The dual integrated frame technology system allows you to join the silicone skirt to the lens frame without major interruptions of the curvature continuity. The result is a mask with an extremely hydrodynamic shape and, visibility being equal, a significantly smaller size. Mask features inclined and inverted tear-drop lenses for improve downward visibility, a Cressi's patented design (US 6272693). The field of view obtained is particularly wide, laterally and in the lower zone. The skirt, in the front part, has a structural silicone insert which increases the sealing ability of the mask and creates an exceptionally pleasant chromatic play. Easy-to-use buckles for quickly strap length adjustment.
