The mask is made using the IDF system. The Integrated Dual Frame is a technology that consists of the joining of two rigid frames producing a drastic reduction in the internal volume. Patented by Cressi US 20140013494 A1.
The raked lenses, with their inverted drop shape (Cressi patent), are quite small and are inclined as close to the eyes as possible to improve the downward visibility. The lenses may be replaced with prescription optical lenses ideal for myopic.
The innovative face covering is crafted from High Seal Silicone, providing unmatched comfort and an airtight fit perfect for underwater activities such as scuba diving, snorkeling, and freediving.
The thickness of the frame has been reduced to such an extent as to make it practically invisible when the mask is being worn.
The frame uses the exclusive patented Cressi system of double injection of an elastomer on a rigid element. The buckles are mounted not on the skirt structure, but on an indestructible element that allows the buckle to tilt and turn without breaking it.
