MIPS: Multi-Directional Impact Protection System
MIPS is a step forward in helmet design. There are three main components to a MIPS-equipped helmet: the interior foam liner, the Low Friction Liner and an elastomeric attachment system between them. In an angled impact, the elastomeric attachment system stretches to allow the foam liner to rotate independently around your head. The goal of this technology is to further reduce rotational forces which can cause massive stress on the brain.
Hard Shell Construction
Hard Shell Construction produces great helmets at a great price. A rugged outer shell is molded and then attached to the EPS foam liner.
In Form™ Fit System
The In Form system makes it easy to dial in a custom fit in seconds - even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6 cm of adjustment and enhanced stability while the vertical tuning feature accommodates different goggles and head shapes for a custom fit, free of gaper gap.
Thermostat Control Adjustable Venting 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 vent of your goggles helps to keep them clear and fog free while maintaining total helmet and goggle integration.
Super Cool™ Vents
Super Cool vents pull cool, fresh air into the helmet while pushing heat and stale air out. By maximizing efficiency and optimizing vent shapes, the collective cooling power of Super Cool vents helps to regulate your core temperature and keep you feeling fresh all day.
For optimal performance of both helmets and goggles Giro products are designed to work together as a single integrated unit. Ensuring a seamless interface between helmet and goggles offers exceptional fit and dependable, worry-free function.
