The Aeon is Giros top of the range road helmet and the choice of the pro-peloton. Its combination of light weight (estimated at 189g for size medium) and 24 wind tunnel vents have set a new standard at the top of the helmet market. Giro haven't compromised the fit to achieve this great low weight and cool design, they've used the RocLoc 5 Fit System and to allow the helmet to adjust from 360 degrees to fit your head, X-Static padding for a plush fitting and odor free helmet. The Aeon comes with a 'slimline webbing' chin strap, it is a lighter weight and a little bit softer under your chin than normal and the minimal cam-locks allows you to easily dial in the fit just perfect.

Wind Tunnel Vents

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.


In-Mold Technology

The in-mold construction process fuses the helmet’s outer shell with its impact-absorbing EPS liner during the molding process, making the liner literally a part of the helmet. This fusion process reinforces areas around vents and ribs, creating a one-piece ‘exoskeleton’ that allows the helmet to be lighter, more durable, and better ventilated than traditional designs.


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.


Roc Loc 5 Fitting System

After more than two-years of development, Giro introduces Roc Loc 5. This groundbreaking fit system provides an entirely 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.
