GiroAries Spherical MIPS Road Helmet(Return to Product Page)

As with most "Premium Product" lines today, it is a bit pricey; otherwise, I have no complaints with the performance or fit. I've worn pretty much all the recent helmet offerings from Fox, POC, Kask, Bell, and Oakley. This Giro is nicer than every one of them (and it's a brand new model, so I expect that it should be...) and the fit is fantastic.

The RocLoc is a real treat, nicer than some of the previous versions, like the Aether and such. I went with the matte shark, which is a lovely primer-ish grey, and the old hot rodder in me appreciates the variety of colors we can get these days. I have a metallic pink Time road bike, so I'd never find a helmet that matches it. I wear either black or grey Sidi road shoes, so the appearance is perfect for me. If you're into race team fanning, they have a few of those colors, too.

As far as protection goes, I aim not to test that, though the last massive crash I had, a mountain crash that left me with a concussion and some significant injuries, was in a Giro, and while that helmet broke in 7 places, it stayed together, and kept me from worse injury. I keep it on my bike wall as a reminder that I'm actually mortal.

BL - Great product, great fit and finish, feels like a bandanna on my head, and the vents work great. Bike Tires Direct has a great price and IN STOCK (which is no small thing right now..)

Nothing else to say is there?

I bought this helmet to replace an aging Giro Synthe II helmet. The Giro Aries helmet fits my head better, is better ventilated, has a better impact safety design & rating (see Virginia Tech safety website). Because of the better ventilation, I feel that the helmet is somewhat "cooler" than my old Synthe II. I live at 35 degree North latitude & summers are hot, humid and windy. My riding routes are lumpy and between 25 & 35 miles long. The Aries helmet does a okay job at trying to direct sweat away from my brow but sweat still runs down onto my glasses.

If you have a round head this helmet may not be a good fit for you. I think this is a very good helmet and may be worth the asking price. It certainly is for me. Keep turning the cranks! ??

I own (2) Giro Aether Helmets. One in Black and one in White as well as many retired previous versions. The Aether model are good helmets and I will continue to use them for now. I have been wanting a Giro Aires for some time, but the price did not make it practical. I finally decided to get the Sharkskin Aries gray version when it went on sale recently. In my opinion the Aires is the best Giro helmet so far. It is not as wide as previous versions with great venting and wraps around the top of my head much better. I like the Aires styling over all previous Giro helmets. I will probably buy some other colors when the price drops as the next version is introduced.

I recently purchased the Giro Aries Spherical MIPS Road Helmet in matte black, size medium, and I'm thrilled with its performance. The sizing is true to size, fitting my head perfectly without any guesswork. The helmet is incredibly comfortable, with soft padding that doesn't irritate even on longer rides. The head adjustment system is intuitive and secure, allowing for a snug, customized fit that stays in place.

Visually, the matte black finish looks sleek and stylish, avoiding the bulky appearance some helmets have. It doesn't make my head feel or look large, which is a big plus for aesthetics. Most importantly, the helmet feels safe, with the Spherical MIPS technology providing confidence in its protective capabilities. Overall, this is a fantastic helmet that balances comfort, fit, style, and safety perfectly. Highly recommend!

I recently purchased a matte black Giro bicycle helmet, and I'm absolutely thrilled with it! The sleek, minimalist design looks sharp and modern, making it a standout on the road. The fit is spot-on, with Giro's adjustable ROC LOC system providing a secure, comfortable feel without any pressure points, even on long rides. It's lightweight yet feels incredibly sturdy, offering peace of mind with its top-notch safety features. The ventilation is fantastic'plenty of airflow to keep me cool during intense rides. The matte finish is not only stylish, but also resists scratches and smudges. Whether you're a casual rider or a serious cyclist, this Giro helmet is a perfect blend of form, function, and safety. Highly recommend!

Overall, I really wanted to like this Helmet. So much so I brought two different sizes and neither worked for my head. I first tried the Large. Though the ratchetting system locked down around my head, it was far too deep which required me to either keep is sitting high and hover over my head or sit right on top of my eye brows. I returned and tried the medium, which had the perfect dept but was just 1 cm too tight.

I recently purchased the Giro Eclipse Spherical MIPS helmet to replace a Kask helmet. Though my Kask fit well, this helmet is much more confortable from both a fit perspective and airflow. I use it for both long road rides and commuting. This helmet is incredibly comfortable and lightweight. Initial adjustment was very easy and getting it dialed in was great. It is definitely the most comfortable helmet I have worn. I highly recommend this helmet!

Best I've found (but haven't tried many other high end helmets) for fit weight and comfort. Usually wear small, but small is too tight over winter head gear. This is a med and works well as a winter helmet. Recommended.

Would have gotten an Aries Spherical in a black and fluorescent yellow or orange combo if it had been available NOT in a team color design, for added safety/visibility. However, once I received the Matte White Charcoal Rush version with the dark gray graphics around the rim, I found it provided very good visibility on the road, and looked kind of cool.

My only dislike was the thin back neck plastic that bites into your neck if you are follicle challenged or do not wear a cap to cover it. Once I realized that you could reposition the back neck plastic it became much more bearable. Helmet looks cool, it's light and now pretty comfy. No problem with shades in the vents falling out.

I bought it because of looks, light weight, and very well received by reviewers.

It is amazingly comfortable that doesn't even feel a helmet is on, so well vented, very effective in trapping sweat, overall a very satisfying purchase.

Initially back adjustment dial and the plastic frame was scratching the neck, which was disappointing. But the issue got resolved after adjusting the plastic frame to match the shape of my head and loosening up the dial a little.

Purchased this helmet as an alternative to the POCs I've been wearing the last few years. The looks are great, it is light, and the venting is wonderful. But in my opinion there is a serious flaw that you all need to be aware of if you're, um, a bit larger.

The MIPS straps in the back hang very low compared to other helmets and the plastic is very thin with rough edges. If you just try on the helmet you don't notice this. But if you, like me, are a bit thicker but still ride with a fairly aggressive position, those thin straps will dig into your neck right below the base of your skull even when the helmet isn't strapped in with any pressure. You turn your head and these things become little plastic knives. In my case, after my first ride, it was simply hot spots and what felt like a scrape. Yesterday, after trying to stretch these and sand them (they are so thin you really can't do the latter) a 90 minute ride with climbing, where my head position was really stretched to look up the hill, it was so bad that I ended up with scabs on the back on my neck from these things. Talking to Giro didn't help and they had no adjustment suggestions. So into the trash this goes. If you are a bit in the larger side where you might have a bit more skin back there, avoid this helmet. Which sucks to say because it is otherwise super comfortable just trying it on and looks great.

Helmet bought to replace a Giro Aether MIPS that has seen lots of service. Fit is consistent with previous Giro MIPS/Spherical helmets, size small for 5'1" female.

Helmet is very light and well-ventilated. Very comfortable on all length rides; don't even notice it is there. Have already had some days in the low 80s in Eastern NC with high humidity, and airflow has been excellent.

Also purchased the RocLoc 5 LED light. Light installs easily and is surprisingly quite visible from the rear and sides when standing. Have long hair which fits well through the back of the helmet, and when on the bike and stretched out even a small bit, the hair all but covers up the light. Have tried securing the ponytail more tightly, but it still largely obstructs the light. The concept is great and probably works well for riders who are more upright and/or with shorter hair, but may not be effectively visible otherwise.

Replaced my old Giro Ather, I think, since the Aries is a updated 'Spherical' MIPS helmet. As a helmet it is exceptional as my previous one was. But, the previous model had solid retention of goggles/sun glasses which this one definitely has not. Take caution not to use it for this purpose and lose or damage expensive eyeware.

Virginia Tech 5 Star Helmet that feels like wearing nothing at all. I absolutely love it!! Best helmet purchase ever.

I got this helmet because a I needed a new one and looking at the recent safety rating it ranked at the top. After a recent crash my helmet looked fine but then later I saw the foam was cracked inside!

The MIPS system conforms nicely to your head and it quite comfortable - more so than my old conventional Rudy. I still blunder around trying to get the buckle engaged but hopefully that will be sorted with practice. It doe looks quite bulbous on the head. For looks the Kask Aero would be my choice but "safety first"!

Yes, this isn't an inexpensive helmet and you can get some great helmets for around a hundred dollars but if you want one of the best this might be for you. As they say, don't skimp on contact points. Helmets, shorts, shoes, and gloves that aren't completely comfortable aren't worth it no matter the value. This helmet just fits me well. No hotspots and secures so well with the dial on the back that you feel like you don't even need to buckle the strap. What I also really like is the ball-and-socket MIPS system. It really is next-level as it works without having the plastic slides inside the helmet which makes other helmets feel hot and can feel weird with a shaved head. Despite the ball-and-socket design, this helmet has a very low overall profile. In other words... you don't look like a mushroom head. I also sweat a lot in the brow pad design is better than most at wicking the sweat to the sides.

I'm really impressed with the fit system on this helmet. Really fit snug without any binding or pinching, I barely even notice I'm wearing a helmet. I've been riding seriously for over 30 years and this is be far the most comfortable helmet I've ever owned. The ventilation is good, yet still a very aero helmet.

The Giro Aries Spherical combines both a physical and mental edge to create a unique advantage among the best road bike helmets.

It's a comfortable, well-ventilated, well-made helmet with conventional and innovative elements. Together they give me the sense that I'm riding a cooler, lighter and safer helmet, even if there's little if any, meaningful performance difference between the Giro Aries and its top-of-the-line road bike helmet competitors.

VERSATILE FIT

While straightforward, the Giro Aries uses a full complement of proven adjustment mechanisms that fit my head shape easily and well and that I could envision would do likewise for those with a rounder or more oval head than mine.

There is about 40mm of width adjustment in its plastic, sturdy circumference strap at the back of your head. That allows me to better align the strap's shape to the contour of my own noggin even before I start to dial it in.

Many helmet brands have done away with this width adjustment. Instead, some use a thinner, more pliable circumference strap that easily adapts to your head shape (Trek). Others use a strap of similar material and strength as the one in the Giro Aries inside a shell that is more aligned with so-called 'intermediate oval' head shapes at the middle of the bell curve (Specialized) or favoring western (oval, intermediate-oval) or Asian (round) shaped heads.

Giro Aries Spherical

The Aries width and height adjustments and clearance between the front strap and shell combine for an optimum fit for your head and sunglasses and a comfortable sense that the shell is lighter than it actually is.

The Aries uses a small-diameter Giro branded dial to tighten or loosen the circumference strap. The dial, width adjustment, and a simple, sturdy, snap-in height adjustment with three options about 5mm apart are all cleanly integrated into the rear cradle.

I found the height adjustment key to bringing the front brow of the helmet up to allow for my largest sunglasses.

The Giro Aries Spherical straps also seem to draw on old-school design. They are anchored well inside the shell, come together under your ears with an up/down, forward/back clip, are made of a pliable material that lays comfortably against your face and neck that has a Goldilocks 'just-right' length and connects with a basic clip under your chin.

File this under 'it just works.' It actually works quite well.

A UNIQUE TYPE OF COMFORT

A 1-inch, 30-millimeter tall, quite conformable, and sweat-absorbing pad with open slots about halfway up sits against your forehead. It's attached to the circumference strap, which itself sits about 3/8? or 5mm away from the shell.

With that pad design and the variou

I currently cycle about 150 miles per week and I love this helmet. It's incredibly comfortable and airy and most of the time feels like I'm not wearing a helmet at all. I also have some peace of mind knowing (as of the writing of this review) the second best road helmet rating in the Virginia Tech helmet ratings.
