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 scientifically proven to reduce rotational motion when implemented in a helmet by absorbing and redirecting rotational energies and forces transferred to the brain.
The In Form™ system is a low-profile fit and stability system that makes it easy to dial-in the fit and feel of your helmet in seconds even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6 cm of fit adjustment, and the system also includes a separate vertical turning feature that adjusts the fore / aft tilt of the helmet on your head to enhance peripheral vision and optimize the fit of the helmet with goggles.
Thermostat ventilation control allows you to custom tune airflow instantly with a simple, low profile control button on the outside of the helmet. No other system is faster or easier to adjust, and nothing is more effective at keeping you comfortable.
Giro's Stack Vent was developed based on research showing the majority of the warm air that can cause fogging exhausts from the center top vent of the goggle. Aligning the Stack Vent in the helmet with the center vent of your goggles helps to keep them clear and fog free while maintaining total helmet and goggle integration.
The pinch free single handed Fidlock® magnetic snap helmet buckle combines the advantages of two fastening concepts in a completely new way: strong magnets make it easy to open and close, while a secure snap functionality ensures a continuous locking force.
Polartec® Power Grid
Polartec® Power Grid has been engineered to be close to skin, so it offers an exceptional comfort and feel thanks to its bi-component knit construction that uses different surfaces: one that is optimized to move moisture away from the skin, the other to dry quickly. And to enhance the ride even more Polartec® Power Grid includes a Silver Salt that inhibits grownth odors.
