Two interchangeable toric lenses on magic magnets, one sun and one low light, so you are ready for any light condition in a *snap*. Hyperventalator vent system and anti-fog coated lenses mean you can actually see while you ski, and even better when you get it with the GoggleRx prescription insert - which fits perfectly, by the way. A flat top edge makes this goggle fit seamlessly with helmets.
