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.

Fits great and feels comfortable.

Metro Atlanta hot and humid.

My head , somewhat like a softened rectangle rather than round, has alway fit better in Giro helmets (Atmos, Aeon) rather than Bell helmets. The Aether maintains that same feel. Unsure about the real value of MIPS when my head would always slide around a little inside the helmet anyway and would be much more comfortable paying $100 less but the helmet feels great.

Well ventilated, good looking, but a more difficult fit and allows more sweat down the face
rating

Pros: Well ventilated, cutting-edge MIPS, good looks, great straps and adjustments

Cons: Difficult to fit versus prior Giros, allows sweat down the forehead.

I used the sizing chart as recommended given the different MIPS design and it said medium. Medium felt tight at the rear sides of my head -- like a flat spot pushing against the helmet. Tried large but it was HUGE on my head. I ended up with the medium -- very snug, almost too tight, but when I ride I do not notice this. I wear large in other helmets with no issues. The fit of this one is DIFFERENT, so hopefully it fits you better than me.

The front padding is from temple to temple which is nice but it is very thin. It takes very little sweating to saturate the pad and have sweat running down your forehead even with wearing a thicker skullcap such as Headsweats. This is much more of a problem with this helmet than any of my other helmets.

Summary: nice looking helmet with great tech and features, but the fit is more difficult and the front padding is not as absorbent and allows more sweat down the forehead -- perhaps a function of the tighter fit of the helmet on my head.

This is truly an awesome helmet. I was involved a bad bike crash on 1/25/20. I hit my head on the ground at high speed. Luckily, I did not have any serious head injuries, thanks to the helmet. I have 8 other helmets including POC, KASK and LAZER but this is my go-to helmet. Looks like I will have to buy another one from WesternBikeWorks.

Awesome Technology- For me Extremely Uncomfortably
rating

14 of 19 customers found this review helpful.

The technology in this helmet is incredible. It is also extremely uncomfortable. The problem for me is it is cut about half an inch longer than other helmets. It pushes hard on the stems and bridge of my sunglasses and pushes them down on my nose. Because of the longer skirt it also digs into the back of my neck when I am looking up from riding on the drops. No adjustments cure this ... in my case. I would love to have this state of the art protection, but I am not willing to ride without my Oakleys and I cant tolerate the discomfort.

Not as comfortable as previous Giro helmets for me - I have an oval headshape and this one is a little more round than oval in shape. Lightweight, great airflow, loving the upgraded straps. Overall, a very nice helmet with leading edge technology when purchased at a sale price.

Helmet looks great, and I also have the Synthe model. The plastic piece that rises and lowers at the back pinches my skin and is quite uncomfortable. I've adjusted up and down, but still pinches. Also, the exterior plastic decal keeps peeling off at front. I previously returned one due to this, but second helmet also had the same problem. Would not recommend, and may go back to another Synthe.

I've been riding Giro helmets since 1998. I've always been happy with them. I tend to go to the high end helmets for the ventilation as I over heat easily. I have had Pneumo, and Atmos in the past. I ordered the same size for my new Aether and it is snug before cinching.

So far this helmet has been great, very comfortable and great looking. I have not tested it in hot weather yet but from a design perspective it looks like it will be even better than my Synthe.

Unlike a previous comment, the helmet fits great and it allows me to wear my Oakleys without pushing down on my nose and it is very comfortable in a super tuck position. By the way it looks great.

Replaced an older mips giro with this one. The MIPS is totally integrated and out of the way. Fit perfectly right out of the box. Several months of use and seems great. Last Giro mips saved me from any head injury in a 55kph crash!

I've been wearing Lance era Giros since uh, Lance. They've always fit great compared to other brands so I've stuck with them. This is the first "different" model for me, and holy cow! It fits soooo much better than my last Giro. I've had broken retention systems in the past, called them, and replacement parts sent to me no hassle. Good company and great products!

An Excellent Helmet
rating
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.

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.

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!
