You wanted a lighter helmet, a cooler helmet, a better helmet—so we created one. Starting with a full roster of our best features, we optimized every component in the Aeon™ including the shape of the helmet itself, reducing weight by 28 percent compared with its predecessor. We also sculpted massive vents with interior channeling for best-in-class cooling power and integrated the adjustability and comfort of Roc Loc® 5, for a luxurious feel with all the performance you need.

Roc Loc® 5
The Aeon road bike helmet is designed with 24 Wind Tunnel™ vents, internal channeling
Imagine a helmet that gives you an advantage every time the road climbs or the heat turns up. Until now, you couldn't get the benefits of lighter weight and better ventilation in a single helmet.
In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.
ROC LOC® 5 Fit System
The industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing the fit and comfort of helmets,
Roc Loc® 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single
hand. And it’s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.
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.
SUPER FIT™ ENGINEERING
Our proprietary Super Fit™ sizing system is based on “human scale factors” data and over 25 years of handcrafting helmets. By creating helmet molds in up to 4 adult sizes to match the human body’s form, our Super Fit™ sizes comfortably and securely fit riders, and feel like they are custom made just for you.
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.
X-Static padding contains a fiber made with layers of pure silver that is permanently woven into the fabric. Silver has natural anti-microbial performance that helps to reduce odor and regulate heat, so your helmet stays fresh and comfortable, naturally.
