The new standard for comfort and lightweight. The stylish Aeon Helmet leapt out of the pro peloton and into the consumer market with versatile Roc Loc 5 retention, a massive ventilation system and best of all -- a jaw dropping 222 gram weight.

Giro starts off with the tough in-mold construction that put them on the map, then they add a Thermoformed SL Roll Cage for even better impact resistance without tacking on unnecessary grams.

24 Oversized WindTunnel ports shave a little more weight, keep the breeze flowing when temperatures climb and remind us a lot of the popular Ionos model -- one of the most well ventilated helmets out there.

The X-Static inner padding is comfortable and anti-microbial so it resists odor and added Silver fibers help further regulate temperatures. Featherweight webbing straps, a slimline buckle and SuperFit engineering guarantee a precise fit that's downright luxurious.

The Giro Aeon 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)

Helmet? What helmet? ... Ohhh!

This is my second Aeon helmet. Nothing wrong with the first one. I actually love it this got another one to match my other kits.

It is super lightweight, fits me well and straps like a charm. I always forget I am wearing one.

It looks great too. Not the love it hate it helmet. Simply amazing.

Lightweight, comfortable but not the most ventilated.

Having owned many Giro helmets, I bought this without much hesitation mostly because it was so much lighter than the Atmos (which I also own). This is a very comfortable helmet and secures with one-hand. Compared to other helmets I have and currently own including the Atmos and a Specialized S-Works, the Aeon vents are smaller and don't allow the same volume of fresh air flow, in my opinion. If I lived in Seattle or Portland, this wouldn't be an issue, but in Texas last weekend, it was about 99 degrees in the shade and this helmet made me feel every degree.

It is still a great helmet, but the Specialized S-Works is as light and better ventilated - but more expensive and hard to find. I will wear my Aeon when it cools off!

Best helmet I've ever owned

This helmet is super light, very comfortable and flows more air than any I've owned in the past.

Fit on this seems to be better than older GIRO models as I've always had a Bell helmet shaped head.

The new retension system used is easy to use and keeps it in place without being uncomfortable.

Great helmet

Great helmet, lightweight.

Will always buy Giro helmets. This was a replacement for one I crashed in. There is a spot in the back for a light to be secured (zip-tie). I got the bright orange helmet. Great for visibility.

The locking system is great, fit is perfect.

I will always buy Giro's best helmet.

The latest retention/adjustment apparatus is a nice upgrade. The new straps are smoother against the skin. The ventilation is definitely a noticeable improvement with this design. Take it from someone who has broken a Giro helmet in 5 places while doing a header at 22mph...buy the best helmet available...save money somewhere else. This is a great helmet. And, it's available in bright orange...be seen.

What helmet?

Yes that was my reaction because I didn't feel wearing one. I bought this helmet to replace my Prolight. This one fits way better. The prolight seemed to be a bit narrower side to side, so if I need to wear some sorts of head warmer in the winter, it felt very tight. While the Aeon is about 14 grams heavier than Prolight in size M, I feel the the Aeon even lighter due to its comfortable fit. And the loc 5 retaining system is great, it creates a comfortable snug fit and can be adjusted on the ride using 2 fingers. My only concern is the durability of the loc 5 system, it's a very minimal design for light weight so I don't know if it last for the life of the helmet, but only time will tell and I hope I'm wrong on these. Highly recommended.

This helmet stood out in my cycling group both aesthetically and aerodynamically.

Primary use of this helmet is for road cycling. Often times traveling at speeds over 45 mph. I am a longtime Giro customer and safety is my first priority. Giro hit a home run with the Aeon in safety, ultra light weight, cooling, aerodynamics, and styling. Biketiresdirect delivered on price and on time without any problems.

I got the Aeon for primarily fitness riding in South Florida. The summers here are unrelentingly hot and muggy. Any improvement is a godsend. The helmet is very light, very comfortable and has excellent airflow. I recommend it highly.

Great weight great protection bad pads

The helmet is incredibly light weight. It's vents air flow well. For the price of the helmet I feel the padding damages too quickly especially along my forehead. I recently was riding and my front tire was going flat and I didn't know it when I made a quick tight turn and went down so quickly me head and side of my hand holding the handlebars took the complete impact. The helmet saved my head but I still suffered a concussion. The helmet was slightly dented and at first inspection I thought the foam was un damaged but a week later I noticed a crack in the foam close to the impact zone. I believe it's a great helmet and the best part was last week BTD had a sale on the Aeon and I got a new replacement for [$]. I would definitely recommend this helmet to anyone but I know the price can be prohibitive.

Light and cool

I was looking to get some better ventilation and perhaps shed a few ounces. This helmet does both nicely. The latest version of the Roc Loc is a nice improvement. Perhaps it is just me, but the padding in the top is not as comfortable as in my previous helmets (Giro pneumo, Bell Volt), which knocks it down to 4 stars. The straps are also ridiculously long, so plan on trimming after you fit the helment.

Super light

I know it sounds crazy, but the first day, I walked around my garage a couple of times looking for it - only to realize it was on my head!

I bike in TX, so cooling is important. The air channel designs provide plenty of air flow across the scalp.

Be sure to measure your head since the Roc Loc mechanism has limited play.

Nice Helmet, but looks big

Nice helmet. Light weight. But the lightness is replaced with the size. It looked like I had a gigantic head. I ended up sending it back. But, it is a nice helmet. I would say true to size. But, I got a medium and it fit, but really should have had a large. I have a 7 18 head size.

Light and airy

I had read great reviews of this helmet when it was first released, and although it sounded great, there is often so much hype around product launches that incremental benefits are likely negligible. It was also way above my budget, so I got an Ionos instead.

A couple years later and a great sale BTD...

This helmet is way lighter and way cooler than the Ionos. Even with a hat underneath, the Aeon provides more airflow. I'm a big fan, highly recommended.

This helmet is half the weight of the one I've been using for years. Miss my little visor, though. Also, would like softer straps. Great buy on sale. Pretty too. I use it for all road riding, anywhere from 25 to 100 miles a day.

Great Helmet

This helmet is just what I was looking for. Very light, very well-ventilated, very comfortable. I had it adjusted and fitting perfectly in a couple of minutes and that was it. So light and comfortable you forget it's on, even on longer rides. Yet the fit is very secure. And on hot days ( I wear a bandana underneath because I'm follicly challenged) it is as cool as is possible. I stalked the BTD site for a long time to get the right deal and at about [$] off it's a really good price for such a high quality helmet.

Excellent helmet with great ventilation.

I use this product for cycling. I ride 4-5 days a week and roughly 160-170 miles per week. At first I was unsure about the size an the adjustable grip straps seemed very thin. But it fits as it should and stays in place well. Great ventilation, it is light and sits well on my noggin. I thought I got a good deal from biketiresdirect with the sale discount.

It's the best

Very lightweight helmet that fits perfectly on my big head. The very fine size adjustments really help. The ventilation is awesome with the large openings in the helmet. I use a headband in the hot summer months and the combination of wicking by the headband and evaporation from the helmet work well together. And the ability to fine tune the size in tiny increments allows for a great fit with or without the headband. This helmet is worth the extra cost. The only downside is that the helmet is so light you'll find yourself reaching up to make sure you remembered to put it on.
