Performance Innovation.

The Giro Aether MIPS Helmet marks a revolutionary leap forward in rotational energy management. Inside the Aether, a dual-density EPS foam liner helps manage a wide range of impact energies, while also boasting deep internal channeling to provide cooling airflow. Giro's proprietary MIPS® Spherical technology is integrated between the layers of EPS foam - instead of against the rider's head - giving riders the benefits of MIPS without obstruction to comfort or cooling power.

The stunning silhouette is formed by a sleek six-piece shell that surrounds a series of massive vents, with added structural reinforcement via a shatter-resistant AURA reinforcing arch. The final touch is the Roc Loc 5+ Air fit system, featuring 3-way fit tuning, that allows for easy adjustment in seconds.

Features:

  • Sleek road helmet with 11 vents and Wind Tunnel internal channeling for optimal comfort and breathability.
  • Shatterproof Roll Cage "Halo" Reinforcement.
  • MIPS Spherical technology shifts the MIPS system between the EPS foam, rather than next to the skin.
  • Featherweight webbing with Slimline Buckle.
  • Sunglass docking ports in front vents.
  • Ponytail compatible.
  • Compatible with Roc Loc 5 LED (sold separately)

Lightweight, comfortable and visible helmet
by Anonymous
Cycling Enthusiast
Lexington KY

The helmet is lighter weight than others that I have owned in recent years. The MIPS design gives me a sense of safety and I chose the bright colors to be visible to motorists. The tightening mechanism works fine. The chinstrap closure could be more high end, it is very basic.

Long Term Issues

This is great helmet out of the box -- light, comfortable, etc. But over time -- a little over a year -- a few problems creep in. First, the fitting mechanism in the rear is secured together by tiny plastic pins that wear down and then become useless -- the mechanism will still tighten, but it isn't held together so it slips around. Second, the plastic that comes around each side to a point in the front of the helmet peels off from the front and sticks out (pointy and sharp). Several riders in my group have this helmet and I've noticed that the same thing has happened to them.

It is less than two years now and I'm shopping for a new helmet. Disappointing for such a high-end lid. This helmet is probably best for pros who would get their helmets replaced frequently, but for a regular rider looking for a helmet that lasts, not so much.

Giro Aether Spherical MIPS Helmet
by Bryan
Brea

Had to replace my Giro Synthe after taking a header at 45 mph in Big Bear. Replaced it with the Aether, so far so good. The helmet sits lower on the forehead which puts the sunglasses right at the base of the helmet. Will see how that works out? Also the helmet makes noises when the base and outer shell rotate from each other while riding. That my drive me crazy?? Quality, Fit and Finish are Nice.

Expensive, but an excellent road biking helmet.

This is a fantastic-fitting helmet, with a wealth of adjustment points and long enough straps that it's good for my big melon. I love the Spherical addition to the MIPS liner this has to help with impact dispersion in a potential crash, which I hope I never have to test. It's also very light and airy, making it a joy to ride with because you don't hardly know it's there and it breathes well on hot days. Looking forward to trying the companion light for it.

It will fit Aether Helmets. Bought 2 Aether helmets & 1 light. I would not fit on my wife's helmet but would fit on mine with a loud click. the defect is in the Rock Lok system. Hers is a few millimeters thinner than mine. So upon another reviewer's review he Velcro'd the light to the Rock Lok 5. I did the same. IF you buy the Rock Lok 5 light & it will not properly snap into place. Use the 7/8" square Velcro tabs then cut them in 1/2. Attach to light first then to Rock Lok where it is suppose to go.

The Aether MIPS is a great helmet if it fits you well. Helmets are somewhat like saddles. You have to find the right shape/size for your head and various brands are different. For me Giro has always fit well and I have had several. I worked my way up to the Aether and currently own two. I'm back buying another with the current sale. For me the Aether is lightweight and comfortable. I put it on and forget about it. Like saddles, if you are thinking about it during a ride it probably isn't right. If you ride without ever thinking about it and forget it's there then it's working for you. It also holds my glasses - either Oakley or Rudy Project very securely when not on my face.

I did have the pads wear out in mine over time but I found replacements available for order. A second set of pads should get me to the "expiration date" of helmet when retirement is due.

Comfortable and Cool Helmet
by Matthew
So California Paradise

This is a replacement for a ten-plus year old Giro helmet that finally succumbed to the heat, the elements, and for when I have fallen over after forgetting to unclip. The Giro Aether is a very lightweight helmet that fits nicely over my melon and the rear dial attachment is quick and easy to adjust during a ride. The helmet stays cool, and I couldnt say anything but great things about it.

Saved me from serious injury
by maxmf
long island, ny

I bought this helmet for hot summer rides because of the air vents. helmet worked great. I am on my second Giro Aether Spherical MIPS helmet as my first one was put to the test and did it�s job perfectly. I had a head strike to the pavement and basically walked away without serious injury. Helmet took all the impact and cracked but protected me perfectly! Thanks Giro !!!

Is there a helmet more awesome than a Synthe? The Aether is it. Super comfortable, lite, and ventilated. I held off buying a first gen MIPS helmet so I can't compare, but the Aether is the best helmet I have owned.

Put it though the paces last week with a 36-miler and today with a 100K (cold, wet miserable ride)....perfect fit and extremely light, great ventilation coupled with solid aerodynamics. My ONLY compliant, this is the only high end helmet (yes, at this price point...it is high end) out of too many to count in the past 3-years that DID NOT come with replacement sweat pads.....Come on Giro...

Great flitting helmet

I am an avid cyclist. My rides are long and often. I have not ridden with this helmet yet, but the size is perfect. I am between a medium and a large and chose the large for when I need extra warmth for my head. The retention system works great and is very easy to adjust. I highly recommend this helmet to anyone who is wanting a fantastic helmet.

An Excellent Helmet
by Lexington biker
Cycling Enthusiast
Lexington, MA

I am a recreational road rider, with most rides in the 20 to 30 mile range, and occasionally twice that. I like the lightness, ventilation, and compactness of this helmet. Even on sale, it is not cheap, but it looks great and fits my head very well. Over the last 15 years, I have used both high end Giro helmets and Laser Helmets. For a number of years Laser had a definite edge in fit and comfort, but now I prefer the Aether. I think the big difference is how the helmets handle the MIPs technology. I find that many MIPs helmets exert a wierd torque on my hair. Aether does not.

I have used Giro helmets for years, the recent being an Atmos. I really like the Aether. The adjustments are very good and easy to make. It is very comfortable and light. I like the new safety features, which is why I upgraded...it had been about 8 years since I had a new helmet and my wife was suggesting I get up to speed with the new technology to protect my head.

I would highly recommend this helmet. Expensive, but when one considers the importance of head and brain safety, it was worth the spend!

Good looking helmet and a custom fit

This helmet is high quality and fits really well. If you havent used a MIPS helmet it's a tad larger on the sides than the older style Giro I had for years, but it looks great and is not noticeably different in size while riding. It sits lower around the brow area so it can apply slight pressure to your riding glasses, but not a big deal at all after adjusting for it. Now other riders helmets appear to sit too high on the head I have noticed. Great rubber grippy spot to put your riding glasses if out near dark. I would purchase this helmet again.

Excellent helmet - incremental improvement from last one
by TimT

This fits like the prior Synthes, overall. It allows great air flow and I love the neon yellow color. I had a 4 year old non-mips Synthe that is beyond it's useful life, thus bought this. The straps are secure and don't collect sweat. The padding is light but supportive. The two-part design is something I don't notice at all, hope that's a good thing. The only gripe is the front plastic part of the cage leaves some indents on my forehead when I use it, even allowing sun in to give me an odd forehead sunburn during summer. Fall riding so far has been good, not needing a beanie hat so far and still very breathable.

I would purchase again, although expensive, I'm trusting the safety tech is worth it.

True to all the other Giro helmets I have owned this helmet checks all the boxes. Fit is similar to the older Synthe it is replacing but there does seem to be something to the Spherical tech business. Seems the higher up you go the helmet is also lighter. No neck issues on longer rides. Grey straps may show less fading, I hope, than standard black. Good sunglass holders and wide vents are good for head scratching.
