Finally available after years of racing development in Indy, Stockcar,
Outlaw Sprint, and Drag Racing Series. The Super Shark features Simpson's
exclusive "Boundary Layer Design" (BLD). BLD defeats buffeting with
concentric ridges that trip and stall the high speed air flow passing over
the helmet, and secondarily eliminates the helmet's lift or its ability to
raise off your head. Additionally, increased cooling is created by the low
pressure "Gill" Vent Exhaust System. It's a total aerodynamic package. Snell SA 2005: Approved Liner: Nomex® interior
