The Supertech Double Pane, Roll-Off Lenses are specifically designed to keep condensation inside the goggle to a minimum. The outer lens is made from high-quality, impact-resistant, injected polycarbonate material. The injection-molded lens ensures nearly zero visual distortion. An additional Polycarbonate inner lens is sealed to the outer with a layer of neoprene. All lenses have 100% UVA protection. All Roll-Off lenses have built in silicone ""Glide Lines"" to keep the film from binding or sticking to the lens.
