Every pair of Smith shades are made using the US military's Human Systems Integration (HSI) process. This means they take human variables such as fit, optical performance, ballistic performance, integrated equipment, and weapons interface into account in the design process, in order to refine a product's functionality across a wide spectrum of factors.
Driven by the needs of elite level athletes, the PivLock™ Arena features an ergonomic face fit to perform in even the most extreme conditions. Lightweight performance is further enhanced with the two-position adjustable nose piece, slide-on temple ends, and a vast array of performance mirrored lens tints. Beginning of the race or end of the day, the PivLock™ Arena is the ultimate choice.
