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)

I was debating between this and the Lazer Z1. I went with the Lazer because it fit my head just a little better. But I have nothing bad to say about the Giro. Its super light, great airflow and has a classic look that works for me!

I live in New Mexico. The weather is hot 9 months out of the year. This helmet provides terrific ventilation and is light enough not to aggravate a neck injury. Plus, it looks great.

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.

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)

Always have had a great fit for my melon with Giro, starting with the original Ventoux(which got busted in a road race). Here to talk about it. Retention system, Roc Loc 5, easily adjustable even with cold weather gloves. Great ventilation hot days and adjusts to accommodate a head band or skull cap in cold weather.

I have a ridge on the top of my head so finding a helmet is very difficult and this helmet fits great! It is also the coolest helmet I've ever had too. On those long hot summer days you can really feel the wind blowing through your hair.

After owning several other helmets, I decided to buy the best and lightest available. Sure, everyone wants the Synthe but this helmet fits great, has tons of adjustments and is super ventilated. And as always, WBW has the best price, fastest shipping and amazing customer service.

I needed to replace my Lazer Helium, which was a nice, light helmet, but it never quite fit my head right - the arms of my sunglasses always overlapped the back of the helmet. I wasn't sure which size Aeon to get because my measurement was right on the cusp between Small and Medium. I went with the Medium and it's a good fit. I think the Small would have been fine too. So the fit is versatile, it's light and airy, the little stripes are cool, and it's super comfortable. I'm so glad my sunglasses don't bump against it either. This is a pretty perfect helmet.

Tough to beat the fit and feel of this helmet! I was sized between the large and the Medium and found the large way too big and sent it back to WBW for the smaller size and it fits great! This helmet is so light with great coverage and has amazing flow While riding. I have a collection now of 8 different helmets, some Mountain and some Road and there's no doubt this will be my go to lid for those hot days to come!

I ride about 100 miles a week. My old helmet is a Giro Pneumo helmet which I have had for several years. It was time to replace it. The Giro Aeon is a great upgrade to my old helmet. The Aeon is lighter, easier to adjust, straps are lighter and more comfortable under my chin, better fit than the old helmet, lots of cooling vents and overall provides great protection. I did look at other helmets but came back to Giro. This is my third Giro helmet and they have always performed well. Looks and feels well constructed. I believe it's an important investment in safety.

I've had several Giro helmets in the last 20 years, always wearing them longer than recommended for safety's sake. The Aeon popped up on a Google search (and Western Bikeworks). It's lighter than my Ionos and ventilates well, perhaps too well now that winter's coming on. The straps were unusually long, even for a size large. I fixed that with a hot knife. I keep going back to Giro because the helmets fit well.
