Zamp proudly introduces the RZ-38 DIRT, a Snell SA2025 certified helmet built specifically for dirt racers who demand protection, comfort, and focused performance at an unbeatable price. Featuring the same proven shell as our standard RZ-38 model, the DIRT version is optimized for off-road use with reduced venting to block out dust and roost. This model includes a pre-installed upper chin curtain to prevent dirt and debris from entering the helmet through the chin bar area - a key feature for demanding dirt track environments. Like the original, the RZ-38 DIRT features a lightweight composite fiberglass shell and the all-new 29 Series interior - fully removable and washable - allowing drivers to refresh or customize their fit after intense racing conditions.
