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)

Expensive, but worth it. Light as a feather.

Excellent helmet, light as a feather on my big head. The new(er) Roc Loc 5 retention system is much, much better than previous models. It fits very well against my shaved head, and its adjustments allow me to wear varying thickness levels of neoprene skull caps underneath when it is cold. And, you will need to wear a skull cap underneath it when it's too cold for you as the air flow through this helmet is phenomenal. I expect this will be a huge improvement over every other previous helmet I have owned come summer (or late spring) here in CA when it's hot. The airflow should help keep my head cool when.

Also, it's far more aero than any other previous Giro or Kali helmet I've owned.

Super light and cool helmet!

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.

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.

Great Helmet

Bought to replace an atmos that was just getting old. Agree with others on the roc loc feeling less substantial, but no issues with adjustability or durability. Great fit and super light.

Still the best helmet you can get.

I have used the Giro Aeon for a few years. I thought it was time to update to a more recent helmet, so I tried the Kask Mojito and the Giro Synthe MIPS, the latter being the newest top-of-the-line from Giro. Both were at a huge discount after Thanksgiving so it was a good occasion.

- Kask Mojito fits nice, but the leather chin strap lacks flexibiliry. Also people mention that this helmet makes them sweat a lot, and I tend to sweat a lot, so this was a negative point

- Giro Synthe MIPS fits nice, and it has the latest technology.

HOWEVER both newer models weigh 60g more than the Giro Aeon (size L). My Giro Aeon is 250g, both Kask Mojito and Giro Synthe MIPS weigh 310g. This is 'only' 60g, but it is more than 20% heavier, and this makes a HUGE difference. It makes me notice the helmet much more on my head. So latest technology or not, I'm going to stay with the Giro Aeon for the time being.

Best hemet I have had... great fit, cool and looks good

I use this helmet for both road and mtb.... the last Giro I owned probably saved my life in a 25 mph road bike crash. Helmet was badly damaged but saved me from serious head injury. I place my trust in Giro helmets.

Possible defective or poor design

I had this helmet about two months and today was riding and the locking mechanism just broke mid-ride. That was nerve-racking because I had to use the straps to tighten it to get home. I am unsure if it was just a bad helmet or poor design but have written customer service at BTD to see what can be done. Please note, this review isn't directed at BTD but rather at the helmet. Regardless, I won't be purchasing another one of these helmets and will go back to Specialized.

Light, well ventilated and comfortable, the look is too wide, a little mushroom-like.

Light, well ventilated and comfortable, the look is too wide, a little mushroom-like. The cost is average for a helmet this light, good deal when on discount. Helmets are generally overpriced anyways.

Giro quality

I am replacing an Atmos helmet that I have had for years. The Atmos was a great helmet, but I recently broke it against a tree. It did its job very well. I was looking at Lazer helmets, but after seeing how the Giro held up and saved my head, I decided to stay with the same brand again.

I have heard some of the Roc Loc's have broken and they don't look as stout as my older series adjuster, but overall the fit and finish is great. I'll see how the adjuster holds up. So far I've used the helmet 18-20 times and have not had any issues. It has been plenty cold here this winter, and I can tell the ventilation of this helmet is going to rock this summer.

Great Helmet, Super Bright &40Highlight Yellow&41

I got the highlight yellow in large. I have a fairly large head and not all helmet brands will fit me. This one has enough room for a winter cap. Comfort and visibility are great. Ventilation seems good, but I haven't had any hot days to put it to the test. The adjustment dial is easy to use even with heavy winter gloves on. I got mine during a sale and it was much cheaper than competitors helmets, so it was an easy choice.
