Simpson Racing 7950011 SD1 SA2020 Dirt Track Racing Helmet - Small, White

The Simpson SD1 represents a new evolution in Simpson automotive helmets — engineered to be Simpson's lightest and most aerodynamic helmet ever produced. SA2020 certified and hand-built to order in New Braunfels, TX, the SD1 delivers premium protection, a precision fit, and a thoughtfully designed feature set for serious racers.

Purpose-Built Design: The SD1 is purpose-built for open-cockpit and open-wheel racing environments. Its ventless front chin design keeps dirt, dust, and debris out of the helmet, making it an excellent choice for dirt track, drag racing, and any application where environmental exposure is a concern. A front chin spoiler (duckbill) improves stability at speed in open cockpit cars.
