Internal Volume is Minimal, Doesnt Require Intentional Equalizing
The Cressi Nano mask was specifically designed for freediving or spearfishing and utilises an extremely low internal volume and hydrodynamic shape to reduce drag and improve efficiency. The twin lens frame provides a strong but lightweight structure to the mask. The bridge across the nose has been thinned and strengthened to eliminate uncomfortable contact between the mask frame and the face. The reverse teardrop lens shape and closeness to the eyes provides an extensive field of view with little or no visibility of the frame itself. The 100% pure silicone skirt helps to further improve the lower visibility and reduce the internal volume by holding the frame at a raked angle, bringing the lower frame in towards the cheek bones. The buckle system is securely fixed to the mask frame by a strong but flexible rubber that allows lateral movement without affecting the fit and seal of the skirt whilst the swiveling buckle assembly allows the strap to be easily positioned for comfort. The strap and buckle allow for very fine adjustment to ensure the perfect tightness.
