IST’s newest single lens mask gives the diver or snorkeler a great field of vision with its wide lens design. The super clear, tempered glass lens and the supple, hypoallergenic transparent liquid silicone skirt are held together in the new CNC 6000 series marine grade aluminum frame and strong high impact plastic sub-frame. This unique multi-material construction method is tried and tested with the finished product proven significantly stronger than traditional plastic masks. The reduced frame thickness allows the lens to be moved closer to the eyes, reducing internal volume and gives a better view field of vision.
