GiroAether Spherical MIPS Helmet(Return to Product Page)

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...

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.

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.

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.

First of all it fits my head. I have a medium. It doesn't feel like I'm wearing a helmet yet it fits snug against my head. I wear it in the cold & in the heat. It's ventilation works very well, including my glasses don't fog with this helmet. I feel confident that my headvit protected.

Good price for a quality product in result. Feels great on head, light, and does everything it's supposed to do. My old helmet simply wore out after quite a few years of use, so it was time for a fresh replacement. This one handles that perfectly.

I was surprised at how well this helmet fit and it is very comfortable. I like reflective surfaces as they are bright at night but subtle during the day. Very happy with the item and prompt delivery

Have been using Giro helmets for years. This helmet is light and airy. Great price.

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!

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.

Helmets are subjective, right? My deal: Longtime Giro user who switched to Kask Protone in '20. Really liked the comfort and look of the Protone and Protone Icon but had TWO consecutive Icons with a defective retention dial. First one right out of the box, second one after two months of use so switched back to Giro. Aether fits me well and feels better ventilated than the Icon. No crashes in either so cannot speak to relative protection.

I decided that it was time for a new helmet after taking a few spills in the last few years so this was on sale and I am replacing an old model, but only MPS helmets allowed! Fits nicely, has great visibility so it was the right choice.

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.

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.

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.

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.
