The Spy Orbit Goggle is a sleek goggle that remains optically correct (means no distortion) in spite of its wrap around, spherical lens. Its patented multi-angle strap hinge makes it compatible and comfortable with or without a helmet. A dual composite frame gives ergonomic comfort and keeps the lens tight in its place, preventing distortion. Spy?s patented Scoop Ventilation System keeps moisture and fog at bay while you are working hard on the slopes. Moreover, the lens is treated with an anti-scratch, anti-fog coating.
