Giro Aether Spherical MIPS Helmet

I believe this helmet is the best protection and it fits nicely

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.

I tried this helmet at a local store and I like how this fits on my head. Bike Tires Direct had this helmet on sale and so I bought it online. This helmet fits comfortably, it looks very streamlined, and it's very lightweight. When I was using it on 100+ degree rides, it keeps my head ventilated. It was still hot but it was ventilated at least. I also find that the helmet was manufactured in Oct 2021 or after which is the requirement to fit the Roc Loc 5 LED light at the back of the helmet. It's something I couldn't tell on the product page but I am glad this is compatible with the light. Overall, I like the Giro helmet and would continue to make purchases through Bike Tires Direct.

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 am an avid cyclist and Triathlete. I was looking for a well ventilated, aerodynamic helmet that has the most current safety features (MIPS). I found all these qualities in the Giro Aether. I had recently purchased the Giro Eclipse, but was starting to get some hot spots and could not use the helmet for longer rides. The Aether so far has been exceptionally comfortable. As usual, got a great deal on BikeTiresDirect. Happy with my purchase so far and recommend to anyone looking for a lightweight, well ventilated, up to standards as far as safety goes helmet.

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 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 replaces an older non-MIPS Giro Atmos where the Roc Loc feature snapped. This new Aether Spherical MIPS (size M) has excellent fit, and several different types of convenient fit adjustments to really dial it in. Easily accommodates a cycling cap or winter cap as necessary. Lightweight, sharp looking, close fitting with a lot of hi-vis yellow around the rim. Very expensive unless you hit a BTD sale (I did), but regardless of price, I'll take any advantage I can get protecting my noggin in the event of an incident, especially when it looks so fine. Wouldn t change a thing on it.

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.

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.

As others have already stated the Giro Aether is a fantastic helmet. Light, well ventilated, MIPS, and looks great. I've had problems with the fit on other Giro lids (LAS and Smith helmets tend work better for me), but the Aether is altogether different. The helmet is highly adjustable with strap anchor points that can be moved to adjust the fore/aft positioning and make the webbing feel narrower or wider. Sizing appears to be accurate. It's a bit disappointing that such a pricey helmet doesn't come with extra pads (which wouldn't cost much as the padding is quite sparse). Still, given all the features the price is reasonable, especially if purchased during a BTD sale. I like to rinse my lids after each ride, and since I hate putting on a damp helmet I have a rotation of several helmets. I ended up buying two Aethers (in different colors) and will retire some of my older helmets.

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...

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.

Use this mostly for road but works on gravel and mtn bike too.

I've crash tested two Giro Synthe Helmets - both saving me from much nastier injuries. Alongsiiide the safety aspect they were great helmets for keeping me cool, particularly in the hot climates I ride in (Egypt, California, Australia).

I couldn't get the Synthe anymore and finally found this Giro Aether Spherical on BikeTiresDirect for a fantastic price - after visiting more than a dozen brick and mortar stores, and at least that many other online retailers. I was not immediately a fan of the shape (the front) but the helmet is so comfortable, I really don't notice it at all. The strap placement works well for me and the sunglasses ports were something I was keen to have again after the perfect ones on the Synthe.

As for the additional safety of the MIPs spherical, I hope I never have to find out how good it is first hand but I am impressed with how the system doesn't interfere with the airflow or make the helmet bulky. I got the Black FLash version and am glad to have the light reflecting decals. With my history, perhaps I should have bought 2?

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.

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 !!!

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!
