The Supertech Double Pane Vented Lenses are specifically designed to keep air flowing inside the goggles and condensation 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. Strategically placed vent holes across the top and sides allow for plenty of airflow. All lenses have 100% UVA protection.
