Safety First
GMAX understands that purchasing a helmet is much more than features or a design, it’s a commitment to your own personal safety and an investment for your friends, family and colleagues. At GMAX, we understand that it can be confusing to decipher which helmet models are going to work best for you and your family.

DOT Certified
DOT stands for "Department of Transportation" and the standard safety measurement is FMVSS 218, or the Federal Motor Vehicle Safety Standard #218 for motorcycle helmets.
The U.S. Department of Transportation wants to ensure that helmets that are DOT certified, meet strict testing standards. The NHTSA (National Highway Traffic Safety Administration) is charged with enforcing this standard to identify counterfeit/novelty helmets or helmets that do not pass the DOT test.
DOT FMVSS 218 includes extensive testing procedures in 4 different climates; water emersion, ambient, low and high temperatures. The test procedure focuses on three key safety compliances listed below.

Mips
Originally developed by a brain surgeon and a biomechanics scientist, the Mips® Safety System has revolutionized the world of helmet safety. By complementing the helmet with a low-friction layer, designed to move slightly in the event of an impact, the system is designed to help redirect rotational motion away from the head. This is intended to help reduce the risk of brain injury.
Rotational management - Make sure the helmet is designed with a low-friction layer like a Mips® safety system, that’s intended to help reduce rotational force to the head during certain angled impacts.
