GiroAries Spherical MIPS Road Helmet(Return to Product Page)

This helmet really is almost like wearing no helmet at all. I realize that this is specific to me, but I ordered a large and ended up exchanging it for a medium. I'm right at the top of the medium size range in this helmet it fits me like it was custom made. The new spherical technology is really cool and its easy to see how it scores well in testing.

Disappointed in quality of Kask protone. Lasted one year and fell apart. Got the Giro on sale and happy with it so far. Good fit, comfortable and quality finish.

I have this helmet in both white and black. Both were purchased months apart during a Gold Member promotion. I first purchased the helmet for the spherical, multi-level, rotational protection design. The numerous air vents keeps you cool, especially for those heavy sweater. It is very lightweight and I hardly notice I'm wearing it.

I recommend this helmet for its spherical, rotational design, its protection, and its ability to keep you cool.

I sweat a lot on long hot rides, and read that this was one of the best helmets for ventilation, as well as one of the top helmets in the VA Tech safety ratings. Luckily, I have not had to test the safety part, but this helmet is definitely the best ventilated helmet I have ever used. This is the first helmet I have had where I can clearly feel the breeze on the top of my head while riding. In addition, the front padding has a "sweat gutter" that directs sweat away from your eyebrows and down the side of your face, not into your eyes, which is fantastic.

The safety design is unlike any other helmet I have used, kind of a "MIPS on steroids" design, where there are two distinct shells, one inside the other, and the outer shell moves much more than the typical thin helmet-liner style mips device I had on my Specialized helmet. Even with that, the helmet is not bulky and does not stick up on top of my head. I can see how this design would provide excellent protection.

This is the most expensive helmet I have ever purchased, but I can see where the money went: the design, safety features, comfort, and effective heat mitigation make this an excellent product.

My go to helmet. Light, protective, and cool with great venting.

I recently purchased this helmet after owning one that was over seven years old. I guess it was time for an upgrade. It has not disappointed me. It fits well and the contour feels great!

Damaged my Giro Aether so I needed a new helmet and this seemed like the obvious choice. Like the Aether the Aries fits well, is readily adjustable and has great ventilation. Hopefully, I wont need another one anytime soon, but if I do it will be another Aries.

I had a previous spherical helmet for a few years and decided to get a new one. Then I crashed (I'm told). The old helmet took a big hit and absorbed the impact rather than me, saving me from serious injury. This is the type of real-world 'testing' you never want to perform. I got my new Aries helmet the next day.

The new helmet fits well. The fit adjustment works well and easily, maintaining the right setting. It stays in place over my glasses. I usually run hot, so ventilation is very important for me. While it hasn't been super-hot yet, the Aries has kept me cool so far for extended hill climbs in upper 80F temperatures. I ride most days, so these factors are important considerations for a helmet. The only minor quibble is that my mountain bike helmet has a Fidlock buckle which is much easier and more convenient than the traditional "squeeze" buckle on the Aries, but this is very minor.

I haven't done an engineering analysis, but spherical technology makes sense to me. I can't say that no other helmet would have protected me, but there is no denying that the previous one did.

As usual, good prices and delivery from BikeTiresDirect.

This is an outstanding helmet. It provides great ventilation and comfort along with aerodynamics. The design of the shell within a shell is great. This helmet is outstanding, offering excellent ventilation, comfort, and aerodynamics. The shell design, featuring a shell within a shell, is impressive.

This helmet is comfortable for me. It's on the pricey side so I hope it's worth it. Actually, I hope i don't have to test that out!

I bought the Aries as a replacement for one of my Giro Aether helmets which were the top of the line prior to Aries. The big difference in my mind is that the Aether is slightly wider (mushroom) shape as compared to the Aries. I like the way the Aries sits on my head and in my opinion makes my face/head seem slimmer. It if wasn't for the slimmer shape I would have been fine with my Aether. I currently own a Black and a Sharskin version of the Aries and a White Aether which I hope to replace at some point as well. Maybe xMas or Bday present from family. The Roc Loc 5 system is easy to use, comfortable and helps secure the helmet firmly on my head. I have only owned Giro helmets over the years so I guess I am biased, but other than price on the newer versions I am extremely satisfied with the quality and durability.

This helmet is very comfortable and lightweight. It has good ventilation. I've had to retire a few helmets because of crashes, so the number one safety rating was very important. The only thing I dislike is that it doesn't have a magnetic chin strap clasp.

I've been buying Giro helmets since their very first one and have never been dissatisfied. I had a crash in this particular helmet. I landed on the top left of my head with no head injuries. I did have 5 broken ribs and multiple abrasions. That's good enough for me and I replaced it with a new one immediately! It also has good venting and cooling, is very comfortable, and even looks good.

Great helmet especially light and well worth the money.

I'm on my 12th generation of Giro helmets. This is by far the best, most comfortable I've owned. My only 'crash' is with a 9th generation/first gen MIPS. So, fortunately I can't attest to the crashworthiness of the Aries. But given the testing that has been affirmed to, I'm confident of the protection being as good as it was with Gen9 !

Anyhow, I found the strap design, weight, texture, and placement to be more comfortable. And the head 'cocoon' feels really light.

I can't compare this to other brands because I've never tried one that feels as good. I always end up with Giro. You really have to try any helmet on...head shapes differ and different brands accommodate.

With that, I appreciate the generous return/exchange policy of BTD. While I've not had to use it, knowing it's available makes online purchases more comfortable (as well).

I love this helmet. The fit is awesome and it is really comfortable. The safety is top notch too. Unfortunately, I was involved in a bad accident, but the helmet did its job and prevented further injuries. That's also how I know Giro has a really nice crash replacement warranty too.

Just got my Giro Aries Spherical MIPS Road Helmet and couldn't be happier with it! This was my first time trying the Aries model, and I have to say ' it exceeded expectations.

Fit & Comfort:

Right out of the box, the fit was spot-on. The helmet is incredibly light and well-ventilated, which made a noticeable difference on long rides. The retention system keeps everything secure without pressure points, and the padding feels premium.

Safety & Tech:

The Spherical MIPS system gives me peace of mind. It's great knowing I've got that extra layer of protection without sacrificing comfort or weight. Giro nailed it here ' it's impressive how advanced the protection is without adding bulk.

Style & Build:

Looks sleek, feels high-end, and the build quality is top-notch. You can tell a lot of thought went into the design.

Deal & Purchase:

I picked it up from BikeTiresDirect at a great price, and the shipping was fast and hassle-free. They had one of the best deals I could find anywhere, and I'll definitely shop with them again.

I didn't realize how bad my helmet was until I replaced it with this one. The fit is very comfortable. It feels secure and the lock system has a nice gradient. Airflow is very good. It holds all of my sunglasses (100%, Limar, Ekoi) securely no matter how I'm riding. The padding is very soft and absorbs pretty well. I'm a heavy sweater so this was important to me. I have no complaints.

I used the helmet for one year before the crash and it was perfect for fit, comfort, and breathability.

I landed on my back, and the back of my head immediately whiplashed onto the pavement hard with so loud a sound I thought the helmet would be trashed. While there are four markings on the helmet from the impact, it wasn't destroyed as expected.

Most importantly, I didn't get a concussion. I had a crash three years ago that involved a bad concussion, and you don't ever want to get one trust me. I could not believe how softly the impact was on my head, especially considering I cracked a rib.

For me, the choice is clear. The helmet must have Spherical Tech. I bought an Eclipse to replace the Aries for my road riding and will continue to use the Aries for gravel because it doesn't appear to be compromised.

There are other helmets that I think look way cooler, and I wish the Eclipse didn't look so heinously Martian Domed. I had just bought a Utopia Y on backorder, then right after the crash canceled the order and bought an Eclipse. Funny how priorities can change in a NY minute.

Light, nice fit with great airflow, happy with the helmet and as always fast shipping
