Engineered for performance, Zamp's newest premium DIRT helmet, the RZ-67D is built for serious drivers who demand comfort, airflow, and cutting-edge technology.
Sizing Your Zamp Helmet
The RZ-67D helmet is available in sizes X-Small to 3XL.
Like many helmet brands, Zamp determines the size of their helmets based upon a driver's 'hat size,' the circumference around the head just above the ears, and along the top of the brow.
