Giro
Aether Spherical MIPS Helmet

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.

Good service Easily to return and exchange

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.

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.

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!!!!

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...

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.

I use the helmet on all my rides. It is light and comfortable, and fits my head without any undue pressure points. It works with all my Oakley sunglasses. I have used several winter caps under it, and with a twist of the knob it adjusts for a perfect fit.

I crashed once, but did not get to test the helmet as there was no head contact with the ground. I hope to not test the helmets crash worthiness.

Ive been an avid cyclist for 35 years averaging 500 miles per weekalways with a helmet properly attached to my head! Over the years Ive had every top-end helmet produced by Giro. The Aether is by far the best helmet Ive had! While I cannot attest to its crash durability and protection, this helmet is very comfortable, easy to fit, and highly ventilated. In all previous models, I had to wear a headband to prevent sweat from getting into my eyes but not so with the Aether. Its air channeling is simply the best. For those who ride at night, a taillight and headlight can be attached to the helmet without interfering with the MIPS liner.

I've worn Giro helmets for as long as I can remember, and the thing that is most outstanding is the fit. However, in recent years some of the retention materials of Giro helmets have become marginal and I find the useful life of these expensive helmets to become quite limited. Having said that, someone at Giro must have gotten the message because the Aether helmet is definitely built with much better quality and materials. The design of the helmet within a helmet is revolutionary and makes this not a superior safety device but more comfortable for long rides as well. I must say you pay dearly for these features, as this is more than I've ever paid (or hoped to pay) for a bicycle helmet. But considering all the safety and quality, I say it's pricey but definitely worth it.

Have not crashed so cannot comment on that aspect. But.. It is light and very cool. Trust the ratings for this helmet, and they are very good. Also like the white to help stay cool in the summer.

This is a highly visible very comfortable helmet with top of class newest MIPS SAFETY FEATURES

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.

The giro helmet was expensive, but what is it worth to keep you brain together. It is light weight and adjusts easily. Glad you had it in stock.

Thank you.

Road cycling, ~200 miles per week. Love this helmet. Comfortable with plenty of vents for cooling.

I love everything about this helmet. Great upgrade from other Giro helmets I've had in the past. Amazing fit and so comfortable!

I use this for road riding and am pleased with the helmet's performance (although I haven't tested it for it's intended purpose of crash protection). I like the ventilation at the front of the helmet, the air coming through the vents is very noticeable although it seems like the airflow over the back of my head is not quite as plentiful as on other helmets I own (Bell Zephyr, Giro Aeon). The fit is great for me (I wear a medium) and the roc loc system works well. This helmet seems to sit further down on my head than others and I like the additional coverage but it sits low enough that it interferes with one pair of sunglasses with larger frames. While I read they claimed it is less bulbous than it's predecessor, from a style perspective it still hews to the mushroom head look.

I have enjoyed the comfort of the Giro Foray mips helmet for sometime. However, when I recognized the technological advancement of the Giro Aether mips model, from a safety standpoint, the only logical conclusion was to purchase the Aether model.

Since purchasing the Aether model, I have worn this helmet dozens of times over hundreds of Colorado roads this summer. The Aether helmet is noticeably lighter and more comfortable than my Giro Foray helmet, yet fits snuggly with the adjustable wheel at the back of the helmet. As advertised, the flow through ventilation of the helmet has kept me cool, even on some hot afternoon rides.

When you read the advanced safety features of the Aether model mips design, you realize this is the design to wear, but hopefully never to depend upon. One problem with this helmet now I have to purchase the Aether helmet for the rest of my family cyclists.

My previous helmet was in dire need of replacing so I started doing research for the best helmets of 2019. I was happy to find that Giro was on that list. The MIPS technology was a little new to me so I was a little confused about how it would fit and or work. Don't be afraid of it! I need to say this is the best fitting, most comfortable helmet I have ever used. The MIPS isn't even noticed. I'm also quite happy with the amount of airflow through it on to my head. I would highly recommend Giro helmets, but especially this Aether line.
