The goal of Giro´s Mips®‐equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to the rider´s brain in certain impacts.Roll Cage Reinforcement:- Roll Cage is a light‐yet‐tough web of reinforcement invisibly molded inside a helmet´s EPS foam liner. It helps the helmet to hold together under impact, and provides an extra measure of strength and integrity that you´ll never notice unless you need it.Wind Tunnel Ventilation:- Giro helmets are developed utilizing our proprietary Wind Tunnel ventilation system. This elaborate design combines active vents in the helmet´s shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider´s head while forcing heat and stale air out. It´s the most effective cooling system available, and a difference you can feel every time you ride.Roc Loc® 5 Air Mips Fit System:- In addition to helping to optimize stability and cooling airflow through the helmet, the micro‐adjustable ergonomic and compact dial allows riders to adjust vertical positioning and tune the contact points independently for a customized fit with exceptional comfort.Ionic+® Padding:- Pure Silver is the secret ingredient that gives IONIC+® the power to provide natural, permanent odor protection to keep your helmet feeling fresh.Roc Loc® 5 Air Fit System:- In addition to helping to optimize stability and cooling airflow through the helmet, the micro‐adjustable ergonomic and compact dial allows riders to adjust vertical positioning and tune the contact points independently for a customized fit with exceptional comfort.Specifications:- Weight: 300g- Material: 51.3% EPS: 21.4% PC: 6.3% Nylon: 1.9% POM: 2.7% Polyester: 10% PP: 4.6% FiberglassCertifications:- Complies with the US CPSC Safety Standard for Bicycle Helmet for Persons Age 5 and Older.
