The Giro Aeon™ - The Leading Combination Of Light Weight, Comfort And Cooling Performance. Until now, you couldn’t get the benefits of lighter weight and better ventilation in a single helmet.
But the new Aeon weighs only 222g in a CPSC approved size Medium. Yet it also provides cooling power equivalent to the most ventilated helmet ever made, the Ionos™. Plus it offers the luxurious feel of Roc Loc® 5, and an innovative thermoformed Roll Cage reinforcement. If you’re looking for the best balance of weight, ventilation and comfort, this is the new standard.
In-Mold Construction - In-mold construction fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner. The fusion process allows us to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets.
Wind Tunnel™ Ventilation - Giro helmets are developed utilizing our proprietary Wind Tunnel™ ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head-while forcing heat and stale air out. This significant increase in air channeling makes a difference that riders will immediately feel and appreciate.
Roll Cage ™ - Roll Cage reinforcement is a tough web of DuPont ® Nylon® molded inside a helmet’s EPS foam liner. It provides an extra measure of strength and integrity that you’ll never notice…unless you need it.
Super Fit™ Engineering For Bike Helmet - A great helmet is so comfortable that once it’s on, it virtually disappears. Our proprietary three-size Super Fit system is based on “human scale factors” data and over 20 years of crafting helmets for the best bike riders in the world. The result is pure Skull Hugging Luxury™, a helmet that fits 98% of the world’s population, yet looks (and fits) like it was custom made just for you.
ROC LOC® 5 - After more than two-years of development, Giro introduces Roc Loc 5. This groundbreaking fit system provides an entyrely unique user experience with an unmatched level of comfort, stability, adjustability and weight savings. With Roc Loc 5, you can easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the dial for a tighter feel on rough terrain, then back it off a notch and relax across the flats or a warm climb. Even with these remarkable features, Roc Loc 5 is still nearly 40-percent lighter than its popular predecessor, Roc Loc 4.
X-Static™ Padding In addition to being very comfortable, our X-Static pads provide anti-microbial properties to help keep your helmet fresher, longer. The pads are also machine washable.
Please Note: This helmet conforms to, or exceeds EU Standards only.
