Performance innovation.

The Giro Aether Spherical 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.

Well ventilated, good looking, but a more difficult fit and allows more sweat down the face
rating
by JonJ
Cycling Enthusiast
Brenham, TX

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.

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.

Awesome Technology- For me Extremely Uncomfortably
rating

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.

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.

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!

rating
by Anonymous

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.

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.

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...

I spend a fair amount of time on my bike and find this helmet to be very comfortable. So much so, I don't even think about it being on my head. It is well made and easy to adjust. I like the technology behind it and will hopefully never have to rely on it! I would not hesitate to buy another one.

The fit of this helmet in size Small is the same fit for me as my Giro Synthe (non-mips). I feel it is true to size. I bought the helmet for the added safety and also hoping that it would be cooler than my Giro Aeon or Synthe in the Texas heat. I wore my new Aether tonight in 92-95 degree heat and I could feel the cool air flowing across my head. It was almost like an air conditioner! The helmet is noticeably cooler than my Giro Aeon. I will continue to reserve my Giro Synthe as my winter helmet. The Aether is very comfortable and I certainly did not notice the few extra grams (apx 35) between it any my other Giro helmets. Adjusting the helmet is super easy and I love the new Roc Loc and the sun glasses holder. Highly recommend!!!!

My Giro Synthe helmet was ready to be replaced and I had been drooling over the Aether, so, at a big % off, it was great deal. The Aether has the MIPS technology built in to the helmet instead of being attached to the already made helmet, so the entire interior of the helmet rotates to absorb shock in case of a crash. This seems much better than the Synthe. Fit is very good. I've only had one ride in 85 heat and the ventilation was good.
