How to Measure for Size

giro helmet size measurementTo determine the correct helmet size, wrap a measuring tape around the head, keeping the tape just above the ears and lever front to back.  Once you've determined the measurement, you can use the size chart below as a guide.

How MIPS Works

In a helmet with MIPS Brain Protection System (BPS) the shell and the liner are separated by a Low Friction Layer. When a helmet with MIPS Brain Protection System is subjected to an angled impact, the low friction layer allows the helmet to slide relative to the head. The MIPS BPS is designed to add protection in helmets against the rotational motion. The rotational motion is a combination of rotational energy (angular velocity) and rotational forces (from angular acceleration) that both affects the brain and increases the risk for minor and severe brain injuries. MIPS BPS has been scientifcly proven to reduce rotational motion when implemented in a helmet by absorbing and redirecting rotational energies and forces transferred to the brain.
