The Shark Evoline Helmet is a best-selling modular helmet for very good reason. The Evoline is the only modular helmet available with a flip-up chinbar that goes all the way to the back of the head for true full-face or open-face functionality. With each generation, the Shark Evoline improves. The Shark Evoline Series 2 brought with it big changes: an upgraded retractable sun visor, which extends down farther for better coverage from the sun; the face shield is 9-position adjustable with a stronger seal against weather, it was only open/close before. The Shark Evoline Series 2 ST Helmet, which is slated for a late 2010 release, is built to incorporate Shark's bluetooth communication system, the Sharktooth. As each iteration of this helmet is unveiled, it continues to improve which makes it one of the most versatile and best-selling helmets at RevZilla.com.
