Giro Aeon Helmet -

In the never-ending quest for helmet lightness, one fact makes us rest easy: Even the most feathery helmets must pass the CPSC safety standard for impact resistance. If, for example, you've ever picked up a Giro Prolight or Aeon helmets, you know why this is a concern. It seems impossible that a near-weightless thing like these helmets offers adequate protection. Amazingly, though, they pass the CPSC testing just fine.

The Prolight tips the scale at 200 grams, nearly 50% lighter than most alternatives in its $200 price range. Its lightness comes thanks to several factors, the most noticeable of which is its lack of fit adjustment hardware. Its Roc Loc SL is made from elastic and offers none of the fine-tuning of other Roc Loc models. Furthermore, the strap buckles beneath your ears are fixed and non-adjustable on the Prolight. And while this might seem like a reasonable price to pay for lightness, if you ever choose to wear a cycling cap or winter hat beneath your helmet, the resulting tightness around your head is a bummer.

Enter the Giro Aeon. With the Aeon, Giro's goal is to offer the next generation of superlight helmet design. The Aeon marries the breathtaking lightness of the Prolight and the fabulous ventilation and adjustability of the Ionos.

At 218 grams (size Medium), the Aeon is in the same weight class as the Prolight, but it offers far more fine-tunability to the fit. It comes with Giro's all-new Roc Loc 5 retention system. For starters, the indexed Micro Dial lets you adjust the tension with a two fingered twist. And its three position bracket allows 15mm of vertical adjustment in the retention basket -- enough to fit any head shape comfortably. In another improvement over the Prolight, you get clever strap management. The retention basket has strap holders to ensure that they'll be right where you want them by the time the helmet falls into place on your head.

The Aeon uses in-mold construction to fuse the foam liner to the abrasion and puncture resistant polycarbonate shell as other Giro helmets. However, Giro uses a low-density EPS liner for the Aeon that performs the same important task of absorbing impacts, yet it's 15% lighter than the foam they used previously. Giro took advantage of that weight savings by foregoing the composite reinforcement found on the Ionos. Instead, a thermo-formed SL Roll Cage reinforces the Aeon for maximum safety, yet it's 49% lighter than the Ionos' composite sub frame.

The Giro Aeon Helmet has 24 massive Wind Tunnel vents to suck cool air in the front and flush warm air out the back, even at relatively slow speeds. The Giro Aeon is available in the sizes Small, Medium, and Large and in the colors Highlight Yellow/black, Matte Black, Matte Black/white, Matte Black/color fade, Matte Black/yellow Livestrong, Matte Blue/black texture, Matte Red/black, Matte Titanium, and Matte White/silver.

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 an innovative thermoformed Roll Cage reinforcement. If you’re looking for the best balance of weight, ventilation and comfort, this is the new standard.

Giro Aeon Helmet Reviews:

Positive Reviews:

Yes that was my reaction because I didn't feel wearing one. I bought this helmet to replace my old Prolight and this one fits way better. The Prolight seemed to be a bit narrower from side to side, so if I need to wear any sort of cyling cap or thermal cap in the winter, it felt very tight. While the Aeon is about 20 grams heavier than Prolight in size M, I just simply feel lighter wearing the Aeon due to its so comfortable fit. And the loc 5 retention 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 is my 2nd purchase of the Aeon. My first safes my noggin (only slight concussion )and had a slight dent in it. This helmet is awesome. Very light weight and comfortable. When I saw it on sale on Backcounrty for an incredible price I grab it up ASAP. I previously purchased a pair of Sidi's and saved $100. Amazing ; Thanks Backcounrty for having the best on sale/ close outs.

It is very expensive so I only buy them when it is on sale. Backcountry had some color for sale at 40% and it was worth it. It so light and comfortable. I love the x-static padding. I would recommend the helmet but just too expensive to pay for full price.

Samsudin at Backcountry.com on 11/13/2013

This helmet,by far, is my favorite helmet to date. Its super comfortable and the fit is outstanding. The retention straps are easy to adjust and the helmet is well ventilated. I like the low profile design as well as it provides a little more aero properties. Highly recommended.

WesB at Backcountry.com on 10/29/2013

The helmet is amazingly light compared to the Ionos. The only thing I don't like is my sunglasses, Rudy Project Rydon and Oakley Flak Jackets don't seem to stay in the vents when I try to store them there. On the Ionos I had no problem.

Cameron Schow at Backcountry.com on 11/27/2013

Giro just does is all. This helmet is the top of the line. Looks great, fits amazing, and super light and vented. You'll end up spending this much on any other brands high end model but it probably wont fit near as good. Get one!

Feldy at Backcountry.com on 10/18/2013

I won't reiterate what others have said. Light, adjustable, ..
What I would add is that Giro sent me a replacement RocLoc kit NQA when mine broke. Excellent support

FuelForThought at Backcountry.com on 12/07/2013

I like this helmet, very light, lots of vents, fits very well! I've been using Giro helmets for years, great stuff. No complains on this one. Con:High Price

Bj and Emily Chauvin at Backcountry.com on 03/29/2013

This helmet is the lightest and most comfortable I've ever worn. I forget I am even wearing it...

Crashed it all at Backcountry.com on 09/05/2013

I ride with this helmet as if I was riding without a helmet, Fantastic helmet!

Neutral Reviews:

The Good: I really like the fit of this helmet, and I often forget it's even on my head! The RocLoc fits well and is easy to adjust. Helmet allows tons of wind flow and is very cool.
The Bad: The RocLoc is so lightweight that it is held by 2 very small rivet pieces. Half of one broke off, so the closure device sometimes comes off, but it can still operate when snapped back into place. I've seen this happen on a lot of these helmets. Also, the RocLoc system often gets in the way of my sunglasses behind my ears.
The Ugly: While light and airy, the helmet looks very bulbous on top of my head. Very wide.
