Arai XD4 Vision Helmet The Twin-Cam Shield Pivot System on the Arai XD helmet allows the faceshield to operate fully under a peak that can be lowered for better aerodynamics. Its high-flow peak channels air directly into the front vents. Dual TDF3 top intake vents and Double Delta bridged exhaust vents are designed to draw a significant volume of air from the helmet interior. The shell constructed of fiberglass composite is stronger and lighter and allows the use of softer less dense liner materials for increased rider comfort. An efficient chinbar vent with interior and exterior controls flows fresh air to the mouth area or across the shield interior to help prevent fogging while large chinbar side exhaust vents draw out additional hot air. Arai XD series helmets can be configured with shield and peak peak only for use with goggles or shield only. The peak/visor supplied is not suitable for high-speed use where air striking a side or main surface of the peak may cause difficulty in returning the head to a forward and/or level position. Dual TDF3 top intake vents and Double Delta bridged exhaust vents DOT approved. Meets the FMVSS 218 Standard.Fully removable replaceable and washable liner
