Panovision™ Viewport Increases Field of View. No matter what or how you ride, one factor remains constant: the need for maximum visibility. Whether racing or going on a simple ride in the mountains, the ability to make safe head-checks and see obstacles clearly is critical. The Panovision™ viewport in the new Star helmet 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. Replacement Panovision™ faceshield for the Bell Race Star and SRT Modular helmets. Class 1 optics.
