The Arena Elite meets the highest possible standards for ballistic protection while delivering the anti-fog features that Smith built its name on. These glasses have FreeFloat™ lens technology, which isolates frame-induced stress from reaching the lens. As for the optics, our ChromaPop™ lenses boost color and detail. They're also tapered to correct distortion, a must on the range or in the field.
