Why We Like The Aether MIPS Helmet

The Aether MIPS is Giro's range-topping road helmet, offering a professional-level fit and finish along with superb ventilation and advanced safety features. The standout feature is the MIPS Spherical protection system—an updated version of MIPS that's exclusive to Giro and Bell. Spherical MIPS places the slip-plane technology in between the layers of EPS foam, rather than against the rider's head. This gives us the protective benefits of MIPS without any sacrifice to comfort or cooling power.

Very dissappointed as this is a quality product no doubt. BUT, when in my aggressive riding position all you can see is the inside front of the helmet. It is the right size and I tried to make all the adjustments expected. I guess the moulding is not suited to me.

I had a major crash at over 50 km-h. The helmet destroyed, but my head intact!! I bought another one identical. The MIPS really works! I highly recommend

Fit is great as is the style. For whatever reason, my white helmet has gradually discolored to have orange streaks at all of the creases.

This is really nice helmet. Most importantly for me is the amount of ventilation it provides. Unfortunately I sweat a lot and have always had issues with sweat dripping, mucked up glasses, etc. It is truly the first helmet I have owned where I feel air flowing over my head during a ride without thinking about it. It is very comfortable and light weight. It's the best road riding helmet I have owned in about 35 years of riding and trying different helmets. A bit on the pricey side.

The Giro Aether Spherical helmet is an excellent piece of equiment. It's comfortable, lightweight, and stylish all in one. Thank you, Competitive Cyclist, for the outstanding service and product selection.

I have run the gamut for buying a new helmet to replace my Synthe, which started to pull out more and more of my longer hair. So, I wanted a MIPS but without the yellow discs. I also took the opportunity to try other brands along with Giro, because I've only had Giro helmets and thought others might be better for me. I was especially concerned about having enough space between the helmet and sunglasses. I did order the Aether in my first batch of orders and immediately sent it back because it didn't feel right. After trying some other helmets, I decided that maybe I made a rush decision, so I ordered it again, especially since my husband loves his Aether. Again, it just didn't feel right on me--I was very conscious that "something" was on my head. I've finally decided on the Helios, which was in the first batch of helmets I tried, when I still felt a need to compare Giro to others. The Helios feels good, and I don't think I'll notice it when I actually ride in it. I tried cheaper Giros, a Bell, a Lazer, and a Kask sphere. Of those I liked the fit of the Kask sphere, especially in regard to forehead space. However, I had assumed "sphere" meant no MIPS discs, but it had them, so back it went.

Had this helmet for the better part of the summer... until I crashed and dented and cracked the shell. Spoiler alert it did its job. Though it’s not the lightest helmet I have owned the safety features out perform anything. The spherical mips is no joke. I used this helmet cross county mountain biking, gravel, and road. I would highly recommend this helmet even though it’s pricey. My head is 60cm around and I bought a large.

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 my previous helmets.

Helmet Sizing

Familiarity:
I returned this product before using it

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. :)

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 have purchased the Small but went with the Medium and was happy with her choice.
