Penta introduces all the exceptional features of Matrix and Lince also to the sector of four-lens masks. The Cressi patented raked lenses with “inverted teardrop” shape is continued; this concept is now an absolute must in order to obtain extraordinary downward vision, which allows the diver to see all equipment worn at any time during the dive. Like for the Matrix, the lenses have been brought even closer to the eyes compared to the original design of Big Eyes, with a further increase in visibility, which reaches incredible values. The newly designed frame, combined with a strong-grip rubber material, is of minimum thickness and is invisible all round the bottom of the mask. It extends sideways towards the buckle of the strap with a transparent and shiny surface, made from a very new material that is a lot more transparent than glass and polycarbonate, but even tougher and more scratch resistant than the latter, which increases side vision and allows light to enter into the mask. The new design allergy-free silicon skirt comes with an internal seal ring so it fits perfectly and very comfortably on the face. It has an excellent seal for a wide variety of face shapes, including women and young people. Even though it is a four-lens mask, the internal volume is so reduced that it is even lower than many free diving masks.
