Giro Aether Spherical Helmet reviews and deals for sale

Tim Miller

I really like this helmet. Very light and well ventilated. MIPS allows micro adjustments? Reason for 4-star rating: Because I’m a heavy sweater I’ll be curious to see how it works in the hot summer months since I just purchased my new one in the last month. I have a very large head and the more aerodynamic design of this helmet doesn’t look overly large on my head like… read more my previous helmets.

Helmet Sizing

This helmet runs smaller than described. I have owned many helmets over my 25 years of riding. I measured as usual and it was very uncomfortable without the rear lock even tightened. I would recommend going a size up if you purchase. Hopefully it will be more comfortable for you. :)

Safety is top Priority

The purpose of a helmet is to protect your head. Giro has developed a better MIPS system, in my opinion, based on their experience with ski helmets. Their MIPS system is more robust than the method used in most other MIPS helmets. My head fits more into the helmet than the Giro Synthe I've used for the past 5 years. I do think that the Synthe is a tad cooler because the Synthe… read more MIPS system creates a space between your head and the shell that allow air to flow between your head and the shell however the Aether is fine in hot weather and provides more protection. Have you noticed what the guys on GCN are wearing?? Recommended

Great helmet

I recently bought this for my wife. We ride around 50-60 miles a week and she hadn't updated her helmet in years so we felt like we could splurge on a new one. We are both fans of the MIPS system. She loves the matte blue color and it is pretty rad! Her feedback: light, good ventilation, very wide in appearance but comfortable adjustment system. She has a smaller head and could… read more have purchased the Small but went with the Medium and was happy with her choice.

Cranial Happiness

Ahhh. It just sits there. Feels "just right." And I feel comforted knowing I'm better protected by the perfect fit. Giro nailed it.

Perfect Helmet

I got Matt Black Flash. Super cool. I have had multiple Giro helmets in the in the past. Love them all. This one is the most expensive but I think it is worth it. Newest helmet technology, MIPS, airflow is superb. My last Giro was Synth - the fit, weight and ventilation are great but this model is a noticeable improvement from Synth.

Superb except...

I am a long time Giro customer and have always had great experiences, including surviving a major crash that my Giro helmet was all that kept me alive. This helmet fits great, vents well and is quite light (looks great too). My gripe is with the Roc Loc fit system. It works great...for a while bus as someone with a shaved head who uses sunscreen throughout the warm months, I have… read more had multiple cases where the fit adjust simply breaks. The tiny hinge pin is plastic and I can only guess that the combination of sweat/salt and sunscreen reacts to weaken the plastic and poof! Fit system is a goner. Very annoying and I struggle to understand why Giro doesn’t use a more robust system - BOA maybe?

Rad Helmet

I ordered a medium and have always fit medium helmets. The fit is probably the most comfortable helmet I've ever tried. Other reviewers say they have fit issues but I have not found that to be the case. This is a top notch helmet and excellent in all aspects. Nice forehead pad and minimal padding everywhere else which is nice. Two shell MIPS design is very cool and was the… read more main reason I bought this helmet. Ventilation is super nice as well. Large vents on the top and the forehead even has some finer details to help with ventilation. Straps and adjustment system is also clean and comfortable. It also looks better in person that online photos as well. Super happy with my purchase and hope it never has to be used in a crash, however I'm confident this is one of the best helmets available to protect my noggin. Also the eyewear holder is a genius touch. I sweat profusely and have to take my glasses off nearly every climb to keep sweat off the lenses. I've always struggled to find a quick, easy stash location for my glasses while climbing and this feature is really nice. Glasses feel secure and won't end up falling out.

Super light and breathable

The lightest and most breathable helmet I've owned. It must be more aero than my old Giro Pneumo because wind noise is reduced significantly. Also, the Giro Aether has a round shape, which fits my head. I had to return a couple POC helmets, because they have a more oval shape and the side to side size is too narrow, and the front to back size is too large. The only reason why… read more I didn't give 5 stars are a couple of nitpicks. 1) I wish Giro would switch their strap system to one similar to POC's design where the chin strap and the ear strap are separate. I find that POC's design does not loosen over time, and does not need to be re-adjusted. 2) For a helmet this expensive, I wish Giro would include a second pair of helmet pads in the box.

Finally!

I guess I have a weird shaped head and I know it's right between M and L in most helmets. I'd been looking for about a year and even ordered a couple of helmets here at CS...but, alas, they went back. I ended up doing the brick and mortar route with the only requirement being that it FIT, I didn't care who or how much. Well, of course, the Giro Aether fit perfect on my malformed… read more noggin. Didn't know how much it cost until I was at checkout. No complaints, fits, breathes and even manages to be more comfortable with my head up vs. lowered, which is a bonus.

GIRO Aether Helmet

Been riding with Giro helmets for years and always happy. My Atmos was favorite helmet ever. When it was time to upgrade the Aether was really all that seemed to make sense from Giro so selected based on past history. I ride about 500 miles per month, mostly road in very hilly area. My specific complaint is that the helmet is weighted to the front which causes it to slip forward… read more and down unless it is tightened to the point of discomfort. I have tried adjusting and wearing different weight sweat bands and ear warmers and hats and the situation is the same across all. I will keep as a back-up but now in the market for a new "primary" helmet. I have had the helmet for about 6 months so plenty long to have a good idea of comfort and options.

Pretty cool!

Alright Giro, you've got me! I previously have really hated MIPS, it's hot, hair pulling, and makes your helmet look like it's a size too large for your head (which it sort of is to make room for the soda bottle thing). But this design is really excellent. It's similar to my 6D trail helmet in function but looks really nice and without the hair pulling. Best Giro helmet yet… read more I'd say.

Giro AetherMIPS Helmet

I wanted the matte black/pearl helmet but they were unavailable for months. Ian my Competitive Cyclist "gear head" was able to help me get one. I'm very satisfied with the helmet. I feel better protected. I've used the helmet more that 10 times, and am very pleased with it.

Giro are the best

I had a couple of the Giro Synthe MIPS. I crashed and broke one a few weeks ago. Originally tried another brand that has some new technology. The helmet was unbelievably uncomfortable. Bought this helmet and I am very happy with it. The Synthe MIPS is slightly more comfortable but this one is still great. I've done several 3-4 hour rides with it and have no complaints.

Well, I put it to the test

I just recently decided to update to Mips technology after happily using the Giro Synthe for the last few years. The cost of the Aether was a bit of a deterrent so I first tried the Bell Z20 Mips in Ghost (reflective silver). I found/confirmed that Bell is more suitable for round heads...where Giro favors my large, oblong head. I ponied up and exchanged for the Aether in matte… read more black/ flash (reflective). I should say that the Bell was impressive, and comfortable... particularly the padding design. Also kudos for including a second set of pads with Z20 (take note Giro!). The reflective qualities of the "Ghost Z20" were inferior to the "Flash" of the Giro. So the fit and finish of the Aether impresses, as do the reflective qualities of the Black Flash color. It is a bit less bulky then the Z20. The fit and comfort (to my primarily bald head) is similar to the Synthe. I took a good deal of time getting the straps set up just right for me. Ventilation is comparable or a bit better than the Synthe. Due to the slightly increased depth of the vents (due to Mips design), crosswinds don't seem to penetrate into the helmet quite as well. Unique to this review, I fortunately/unfortunately can attest to the safety of the helmet (what we spend the money for, but hope not to use). On my fourth ride in the helmet, at the back of a 3 man pace line, I caught a bad rut/pothole on a cruddy stretch of pavement that dropped me onto my bars. I almost recovered but went into rider #2's back tire, and I went down/ "tomahawked" very hard at 20+mph onto the left side of my head. In my particular circumstance the Mips did an amazing job of buffering a violent impact. I never lost consciousness or was concussed (did sustain road rash, torn Assos bibs, and numerous breaks in my clavicle requiring surgical repair). The attached photo shows the result. So the Aether is obviously spendy. Is it worth it? In my case...Absolutely (although I wish I had been left to wonder).

Really Nice Helmet

Fits great, nice and light as well. I like the way it looks and it is vented very nicely.

Great Update

I've worn the Aether for the past 6 months and had the Giro Synthe before. The Synthe saved my brain in a crash in Lamb's Canyon on my road bike which made me a loyal Giro fan. I replaced my cracked Synthe with the Aether because of it's sleek look and updated MIPS tech. It is my #1 helmet of choice each morning when I ride because of the fit and aero design.

Will wait for v. 2

Love the idea of this MIPS. The two parts of the helmet really do move. I wanted to like the helmet but it fits really low on my head, barely clearing my ears and barely leaving room for my sunglasses. I also found the retention band in the front scratched my forehead. It's likely my head as the helmet looks different in pictures. Hopefully the technology will trickle down to… read more less costly helmets and Giro will address some of the fit issues in v. 2.

protect your noggin!

Fit: true to size Great, comfortable fit and ventilation. Highly recommended for true protection for your noggin.

Another great Giro helmet

I have ridden Giro helmets since their inception. After crashing back in June, I replaced my Atmos II with this helmet (had to wait until August to get it!). Overall it is a great helmet. Fits well, adjusts easily and is really light and airy. I really like it but only hold back one star because of sweat management. I would like to see Giro do a better sweatband - or build in a… read more channel/groove. But I sweat a lot, so maybe that's more my problem.

Will light and motions vis pro 360 mount properly on the Giro Aether?

Hello, Perhaps I am missing something but the helmets are described as "Pro" based upon their light weight (and other parameters) but I do do not see weights listed? I have some chronic neck pain and lighter helmets really do make a comfort difference. Do you list weights for this and the other "pro" helmets anywhere that one might compare? Thanks

What exactly is the Black Flash color way? Is it somehow reflective? If so, photos of it in action would be great!

I ordered this a few weeks ago...looking forward to getting it. Any idea on when these will ship? It’s said “shipped within 2-3 weeks” for awhile. Thanks!
