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.
