The Giro Aeon™ - the leading combination of light weight, comfort and cooling performance. 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. 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 innovative thermoformed Roll Cage reinforcement. If you’re looking for the best balance of weight, ventilation and comfort, this is the new standard.
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 channelling makes a difference that riders will immediately feel and appreciate.
In-Mold: Our 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.
Super Fit Engineering for bike helmets: 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.
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.
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. Micro Dial: The heart of Roc Loc 5 is this ratcheting, micro-adjusting dial. A simple, two-finger twist of the Micro Dial opens or closes the retention system and each click is audible. Three-Position Bracket: It’s never been easier to change vertical positions and fine-tune fit. We incorporated a three-position bracket that features 15-millimeters of up/down movement. Like the Micro Dial, this system can be adjusted without removing the helmet. Carefully-crafted ergonomic arms are shaped to be as comfortable as possible, yet work flawlessly with Giro eyewear (what we call Super Fit engineering). Dual Pods: These two panels are designed to firmly grasp the back of your head while comfortably cradling the occipital lobe. Strap Baskets: With Roc Loc 5, your helmet straps are always right where you need them. Not to mention this strap basket brings a new level of comfort.

I have owned this helmet for 12 months now and use it every week. Its got great ventilation, fit and comfort. The mechanism to adjust fit is via a micro adjust wheel on the back which works very well.

Rated 5 out of 5 by Anonymous Can't recommend enough!
Believe all the hype! The Aeon does exactly as its supposed to do! I known first hand after been taken down at 40kph+ speed 70k into a 100k cycle, my head and shoulder hit the ground, the helmet split into four pieces, and after about 10 minutes of been dazed I was able to pick myself up and finish the cycle. The helmet is super light but yet absorbed my impact with the road 100%. I ordered a direct replacement that evening I got home. I know its dear for a lid but if you cherish your head go for an Aeon.

Rated 5 out of 5 by Anonymous Купил шлем в прошлом 2012 году. Очень доволен, к хорошей вещи привыкаешь быстро! Легкий, прекрасная вентиляция, нет вибрации и шума от встречного потока. Преимущества начинаешь явно ощущать после первой сотни километров. Рекомендую тем кто увлекается марафоном и иногда любит прокатить с ветерком.

Rated 5 out of 5 by Anonymous Great product at a fantastic price
Seeing this model reduced in price by so much was a no-brainer. This is a fantastic helmet and to say it is light is an understatement. When the package arrived you would have thought it was an empty box!
Fitting is simple and overall very comfortable. I got the black / red version and it looks really smart.
Overall - superb

Rated 5 out of 5 by Anonymous Excellent helmet, I was involved in a bunch crash
In a recent race I was involved in a bunch crash which left me flying over the bars and crashing into tar. My head and shoulder took the brunt of the fall and my shoulder was dislocated. Despite my helmet breaking I had absolutely no concussion, not even a head ache, unlike one or two other guys with cheaper helmets. This is money very well spent, don't save on your head, this is the very best helmet I have ever owned.

I have an Ionos helmet so can only compare this to the Aeon.
The first thing I noticed was the chin strap. It may sound weird but the Aeons isnt as soft as the Ionos so can be a little irritating at first. I cant see much difference in size, though my Ionos is ‘Large’ but after speaking with CR I ordered a ‘Medium’ which fits great.
The Aeon is defiantly lighter but Im not sure I’d spend the extra on the Aeon (I got a deal) I’d rather save a heap of money and stick with the Ionos. For a £180+ helmet I also expected a bag or something
That being said the Aeon is a great helmet

Rated 5 out of 5 by Anonymous Lightweight and very cool
Bought this a few weeks ago and have been riding it since. Very well vented and lightweight so perfect for riding in our tropical climate. It's 100g lighter than my previous Bell helmet which is immediately noticeable.
Very nice bit of kit. I have the white and silver one which looks and feels great.
