F-DUAL is a traditional line monocrystal with especially robust and reliable construction and luxurious finishes. It is fully versatile for diving and snorkeling.
Frameless construction with the silicone faceplate chemically assembled to the glass without the need for a frame. This technology simplifies the structure of the mask, lightens it by optimizing thicknesses and allows a very small volume to be achieved in a single-glass mask thanks to the close proximity of the eyes to the glass. This system guarantees good visibility in all directions, especially to the sides, as it allows a maximum eye/glass approach without annoying pressure on the forehead or upper area of the nose.
DUAL FRAMELESS. This double injection technology allows a third element to be inserted between the glass and the facial mask with a double function: to improve the structural rigidity of the mask and to allow a contrasting color.
The design of the screen with polygonal design perimeter, allows a great panorama in all directions while maintaining contained proportions.
Silicone facial with very stable and versatile "mirror" finishes for all types of physiognomies. The calculated design of the interior spaces combined with the calibrated flexibility of the facial, variable depending on the area, provide great stability of the mask together with great comfort and versatility of adaptation. The facial has a firm and stable adaptation on the face with a very soft contact area and thicker sides to prevent deformation during use. The studied design of the upper area of the nose and forehead allows a great proximity of the glass to the face without annoying contact points.
Fully tilting buckles with immediate micro-adjustment of the strap with one hand by means of two buttons to be activated with the index finger and thumb simultaneously. The anchoring of the buckle system in the frame prevents the deformation of the silicone facial during the use of the mask (typical of the models that anchor the buckles in the facial itself) and the tension of the strap occurs aligned to the plane of the glass, optimizing the level of proximity of the glass/eye and, therefore, the volume and optimal visibility of the mask to suit the user.
It is an ideal mask for amateur and sports use: snorkeling and diving.
