Made from a lightweight fiberglass shell and moisture wicking internal liner, the LS2 MX453 dual sport helmet packs a punch. The chin vents and top vents are fully adjustable, so you can get just the amount of air you need, and there's an exhaust port at the back for true, flow through ventilation. The visor of this helmet has been designed to allow air to flow through and around so it doesn't lift at higher speeds. Made from HPFC (High Performance Fiberglass Composite) shell Multi-density EPS liner Optically corrected face shield Removable/washable liner D-Ring closure Emergency quick release system
