This item qualifies for FREE Shipping in the continental United States!

The Diamondback takes the distinctive design of the Simpson RX and Super Bandit a few bold steps further. The chin bar is extended downward for improved aerodynamics, while more chin vent openings increase airflow. Ribs molded into the top of the shell contribute to aerodynamic stability while further enhancing the aggressive look. Available in White, Black, or Flat Black. Includes one clear face shield with adjustable tear-off posts. Snell SA2010 rated.

The Snell SA helmet rating has been developed to provide the best safety protection for auto racing drivers who are restrained in their vehicles. An SA rated helmet may not meet DOT specifications for street use, such as on motorcycles.

SIZING: Helmets should fit as snug as possible without causing discomfort. Measure head circumference around the largest part of the head approximately one inch above the eyebrows and just above the ears. If a one or two layer Nomex hood will be worn with the helmet, it should be worn when measuring head circumference. If a hood is not available, add about 1/4 inch to the circumference measurement for a single layer hood and 1/2 inch for a double layer hood.
