The I/O 7 is designed for optimized performance and perfected fit: single-pivot quick release for easy lens change, AirEvacTM ventilation for fog-free integration with Smith helmets, dual-axis outriggers that pivot in multiple directions to ensure superior helmet integration, and a frame designed for contoured face fit. All this technology is designed around one of Smith's largest spherical lenses, providing a maximized field of view and 5XTM anti-fog technology. The I/O 7 was designed through a process of reducing elements to only the most essential, so there's nothing getting in the way of a great day on the mountain.
