The Simpson Diamondback helmet has had a major revision for 2021. This helmet combines a new Italian composite shell with a shorter chin bar. Changes to the visor improve fit and function. Most importantly, this helmet provides enhanced impact protection.
Defined "wave eliminators" increase functionality from an aerodynamic aspect. The Viper is recommended for multi-use including Stock Car, Dirt Track, Drag Racing, Karting, Road Racing and Off Road.
