Impact Racing's SXS Side Air racing helmet was designed for the rigors of SXS use, and it's compatible with all popular forced air systems. It features a side mounted air-intake with internal channeling to direct the air-flow to where it's needed most. The redirected air helps to eliminate potential wind-induced mic noise when using a communication system. The forced air system also features an Impact Racing exclusive, adjustable valve. The valve allows for maximum adjustment of airflow from 0% to 100%. The included, clear poly-carbonate shield provides protection from debris, with replacement shields available in Clear, Dark-Tint, and Silver-Chrome. The SXS Side Air helmet can be ordered with additional options installed, such as helmet skirts and communication systems by PCI or Rugged Radios. The SXS Side Air helmet is DOT compliant making it legal for use in the state of CA for off-road vehicle use. Not for competition use.
