Panovision ProTint™ visor for the helmets Star/Pro Star/Race Star and SRT/SRT-Modular. Please note these visors will only fit the Bell Star from 2016 on, and will not the Star Carbon model from previous years. No matter what or how you ride, one factor remains constant: the need for maximum visibility. Wheather racing or going on a simple ride in the mountains, the ability to make safe headchecks and see obstacles clearly is critical. The Panovision viewport in the 2016 Star offers riders additional vertical and lateral visibility over the previous Star and more traditional viewports. This allows the rider to see better in a tight or tucked position and make safer lane changes and head-checks. The Panovision™visor is the only class one optically correct visor on the market. Features Activated by UV light, Bell ProTint™ shields adapt to changing light conditions, providing enhanced vision during any ride. INDUSTRY-LEADING OPTICAL PERFORMANCE IN CHANGING LIGHT ProTint Panovision® shields are rated Class 1 when clear and fully activated by UV light.
