Versatility and comfort go featherweight.

The new Aeon Helmet has quickly become a favorite of the pro peloton with a unique design that borrows heavily from the Ionos and Prolight models. Giro's newest creation manages to combine the best features of each for incredible ventilation, easy fit adjustment and an impressive 222 gram weight.

Unlike the ProLight model, Giro has managed to incorporate the Roc Loc 5 system for separate vertical positioning and fit adjustments, with an ergonomically-tuned adjustment dial that won't pinch skin or pull hair. Technologies like over-sized WindTunnel air ports and the Thermoformed SL Roll Cage provide superior protection and comfort while keeping weight to a minimum.

The Aeon is built using the SuperFit engineering process to guarantee a glove-like fit for riders of many different shapes and sizes. Featherweight webbing a Slimline buckle further ergonomics and weight reduction.

X-Static inner padding with Silver microfibers works to regulate temperatures as you ride. The pads also feature an anti-microbial treatment to resist odors, something your riding buddies will appreciate too.

The Giro Aeon features 24 vents and weighs 222 grams in a size Medium.

Sizes:

  • Small (20" - 21.75"/51cm - 55cm)
  • Medium (21.75" - 23.25"/55cm - 59cm)
  • Large (23.25" - 24.75"/59cm - 63cm)

Amazing!!!
by Sisophous

This helmet is so lightweight I don't even feel it on my head. Often while riding I have to touch my head to make sure I have it on and didn't forget to wear it. Not sure how it will fair in a crash it is so light weight but I hope to never find out. The only thing they could have done to improve this is unsnapping the fasteners takes applying some pressure. It could be made easier to unsnap the lock. I think over time this will become easier from simple usage. If you want to feel like you're riding without a helmet but with protection this item is a must buy. Trust the reviews on this site, most people give it 5 stars and that is what it deserves.

Good color and great fitting helmet!!
by BikerBillOH

I initially saw another cyclist wearing this helmet at a Bike MS ride this summer. I thought this helmet color would work great with my carbon Bianchi bike. It matches close enough to give a good contrast with my bike. I actually found the Giro cycling gloves which matches this helmet locally that puts it all together. The professional styling of the helmet looks great and the fit is very good.

Good bang for Buck

Light, airy, fits well, looks good. Crashed on the side of my head with it (string across polls grabbed and held and dropped me like a rock) and this most def did save my head. It dented but didnt crack or split so its well put together. Only CON is hey dont have a return warranty for crashed like Bontrager and other helmet within the first year. And this didnt have MIPS. But it performed perfectly.

Great For Hot Days, But An Odd Quirk . . .
by Anonymous
Cycling Enthusiast
Williamsburg, VA

This is a great helmet for the hot, humid summer days we experience here in SE Virginia. It has excellent ventilation, it's light and the large size fits my 59cm head quite nicely. However, after three outings I've noticed an odd quirk - a strange, whistling or humming sound. I'm not sure what to call it. A wind tunnel effect? There is something about the configuration of the lower side openings that channels the moving air in such a way as to produce a sometimes annoying whistling sound. At other times it's a low moan, like a cold wind in the winter time on the beach. I haven't been able to tune it out yet. Perhaps over time I'll be able to, but for now it's a bit of a bother.

The Giro Aeon Helmet is super lightweight well vented. My sweat does not rolled down into my sunglasses no more.....That is very important because with my old helmet i was constantly wiping my eyes to be able to see the road. The helmet has a great timeless design ..looks cool.

Good product and great store (Western Bikeworks)

The product fits better than most in that the support at the back of the helmet extends further downward. This gives it a notably more secure feeling than most that feel like they are perched just on top.

Competitively priced helmet with excellent ventilation & easy fit adjustment

As an avid club cyclist, the Giro Aeon Helmet provides excellent ventilation on long rides. The Roc Loc provides added security. The Giro Aeon combines safety & style at a competitive price point.

Light weight and great ventilation
by Dominic
Cycling Enthusiast

I've used many Bell and Giro helmets over the past 34 years of cycling. The Aeon is the lightest I've worn and because it sits a bit above the top of your head air flow is excellent keeping me cool. I tested it today on a very humid day and usually my head sweats like crazy. The Aeon kept my head from sweating like it usually does with most other helmets. I didn't even have to wear a skull cap which I usually use to absorb sweat.

The Aeon is great for warmhumid climates. Wearing it during the winter might keep my head too cool. I will find out next winter.

Great fit, comfort, ventilation and light

I bought a second one in a different color. I have been using Aeon for the last couple of years and been extremely happy with all aspects of it. I have not crashed with it to report on its structure but have done so with it predecessor and it literally gave up its life for me. The pads are shaped and placed properly and direct the stream of sweat to the middle front. Ventilation is one of the critical elements of a helmet for me and Aeon does provide the required stream through the helmet without sacrificing the structure of the helmet. I have a big head and the large size is a great fit. I highly recommend it.

Great Lid

What's not to like? It's very light. Vented well for my tastes. And it works. I know bc I had an Aeon that protected my mellon in a serious crash. My head bounced on the road, about the temple area. Helmet cracked all the way through in 2 places...doing it's job!! Maybe a slight headache at the worst.

So, I needed a replacement and considered other options. But decided to get another Aeon, bc it's light, looks cool, and it worked for me. Hard to argue wthat. A little bulbous, but easily overlooked considering how nice it is to ride wit. Barely notice it's there, then when called into action, it works..(I may have said that already)

Exclusively road riding, it's warm here and my neck is ruined so having a super light helmet that's also very airy is great. Saving the 40 grams from my last helmet is definitely noticeable. Plus the on-sale price was unbelievable! I really like it!

One of the Best Helmets ever.
by KMannix

I have been a big fan of Giro helmets over the years. I have three of these Aeon helmets and they are very light and well ventilated. Giro sizes are consistent and seem to always fit well. In addition, I had a recent crash that resulted in a shoulder fracture and a bump on my head. The helmet held up well and no injury to my head. Thank you Giro. Highly recommended.
