- Crystal® silicone skirt, a special formula that avoids yellowing.
This mask has a particular tapered structure deriving directly from the highly popular Nano-mask patent. The IDF - Integrated Dual Frame Technology System joins the silicone skirt to the lens frame without major interruptions of curvature continuity. The result is a mask with an extremely hydrodynamic shape and a significantly smaller size, with equal visibility. Thanks to the Inclined Lens Patented Technology, 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.
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.
The Crystal silicone is a patented formula for the skirt which prevents premature discoloration and it's softer than the common silicone.
