WINDK VENTILATION Giro helmets are engineered with our proprietary Windk ventilation system. This intricate design combines active vents in the helmet shell with exhaust channels inside the helmet that push fresh, cool air over and around the rider's head while pushing out heat and stale air. It is the most effective cooling system on the market and a difference you can feel on every ride.
SUPER FIT ENGINEERING - Our proprietary super fit sizing system is based on data from "human scale factors" and over 25 years of artisanal helmets. By making helmet shapes in up to 4 adult sizes that match the human body shape, our super fit sizes comfortably and securely fit riders and feel like they were made specifically for you.
ROC LOC 5 AIR FIT SYSTEM: In addition to optimizing stability and cooling airflow through the helmet, the micro-adjustable, ergonomic and compact dial allows riders to adjust vertical positioning and independently adjust the contact points to ensure a custom fit with exceptional comfort.
HARD SHELL WITH BUILT IN HARDBODY UNDER SLEEVE The two-piece shell combines a rugged outer hard shell with a polycarbonate bottom shell permanently fused with the liner for durability without excess weight.
BUILT-IN MIPS BRAIN PROTECTION SYSTEM All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding strict safety standards. The goal of Giro's Integrated Mips equipped helmets is to reduce rotational forces while improving fit and comfort by combining the Mips Slip aircraft with the helmet's adjustable fit system.
