Features

  • Structural Integrity - The proprietary AURA II Reinforcement Arch makes everything possible. These shatter-resistant, translucent twin bridges run throughout the helmet, providing structural integrity without adding unnecessary weight. Aries' ultra-low weight (~5% lighter than Aether), impressive cooling power and sleek, compact shape would not be possible without AURA II.
  • Spherical Technology - This unique ball-and-socket design, powered by Mips, helps redirect impact forces. Spherical Technology also boasts more comfort, improved airflow, and Progressive Layering (which mates two densities of EPS foam to address a wide range of impact energy). The results are clear: independent authority Virginia Tech has rated Aries #1 in reducing the risk of injury.
  • Cool Comfort - Deep internal channels connect with Aries' massive front and rear vents. This system provides a path for cool air to flow over the rider's scalp and exit the rear, taking excess heat with it. Aries also debuts our revolutionary DryCore sweat management system. A soft, silicone bead is hidden within the plush brow pad that redirects sweat away from the forehead and to the temples, where it can evaporate more easily
  • Streamlined Speed - When it comes to going fast, smaller truly is better. To craft Aries, we focused on reducing the frontal surface area to eliminate more drag. Add in tiny details like chamfered edges on the AURA II, and meticulously engineered internal channeling that actually speeds up the air as it exits the helmet, and Aries emerges as the climbing helmet that doesn't sacrifice speed, reducing aerodynamic drag by 4% over Aether Spherical.
  • Lighter, cooler, sleeker, plus all the added protection of spherical technology powered by MIPS and our new DryCore Sweat Management System: The Aries Spherical is like nothing before.

Description

A helmet that feels like it isn't there: the all-new Aries Spherical is like nothing before. Its sleeker form and lighter weight (only 270 grams in size medium, CE certification), deliver sensational comfort and cooling power. Spherical Technology, Giro's ball-and-socket design powered by Mips, adds protection by redirecting energy away from the head in certain impacts, and Progressive Layering with dual densities of Nanobead EPS foam adds more comprehensive energy management. 24 Wind Tunnel vents are maximized by the AURA II Reinforcement Arch, while a plush DryCore brow pad manages sweat and combines with a network of intricately engineered deep internal channeling to elevate comfort. From the proven reliability and adjustability of the Roc Loc 5+ Air fit system, to full lower hardbody coverage to enhance durability, to the meticulous production quality, the Aries is state-of-the-art performance, protection, and style.

  • New helmet time..
Color: Matte Ano Blue Size: Large
Purchased to replace a 5+ year old Giro Aether helmet. Very happy with how it fits. Hopefully I never figure out how well it protects my head in a crash..

  • So-so quality, overpriced. Don't recommend.
Color: Matte Ano Blue Size: Large
Pros: 1. Great safety rating. 2. Good ventilation. Cons: 1. Chin strap clasp is too small - somewhat cumbersome to clasp/unclasp, compared to my previous helmet which had a larger plastic clasp. 2. Ratchet knob to tighten down inner frame constantly loosens. Every time I hit a bump or seam in the road, the helmet loosens up. 3. Pricey for what it is, and its flaws. ... show more

  • Great helmet, may need to size up
Color: Matte Ano Blue Size: Large
Reviewing a bike helmet is inherently subjective, but buying one online can feel like taking a shot in the dark. So I will try to offer some points to consider, as objectively as I can. TL;DNR: the Aires is a very high quality helmet that I think can be adjusted to fit most heads comfortably, as long as you start with the right size. My size large Aries weighs 311 grams, which is almost exactly what Giro specifies (310 grams), but 40 grams more than my old (too old, I know) Giro Atmos. That is the price you pay for the latest rotational protection systems, like Giro's MIPS Spherical technology. It's a fair trade-off, I think, for the highest safety ranking of any helmet tested by Virginia Tech's lab. My last two Giro helmets were size medium and fit well on my 59 centimeter oval-shaped head. But, with the Aires, I had to size up to large. The fit seems narrower than my previous Giro helmets, especially on the sides of the occipital lobe, but the large size was easily adjusted to fit comfortably. Not "like wearing nothing at all," but comfortable, with no pressure points. The vertical height adjustment of the RocLok retention system, which is designed primarily to level the helmet correctly, also made a noticeable difference in comfort. In sum, if you fall between sizes, be prepared to size up. When riding with your eyes looking straight ahead, the ventilation is very good, especially across the top of the head. If you tilt your head down so you're looking at the front wheel, it is fantastic. And the Drycore brow pad really works to keep the sweat from dripping into your eyes. I was amazed how much difference these two features make on summer rides in the southern California desert where I live. In the past, after an hour and a half in 90 to 100 degree heat, when I was wearing my Atmos, my face would be beet red, and I often felt light-headed. The Aries is a remarkable improvement, and has reduced my cool-down time from twenty minutes to five. I was worried that the brow band would feel hot, but that is not the case, probably because the rest of the forehead is so well ventilated. I chose the Matte Ano Blue color, which I suspect is one of the least popular. But I think it looks great in person, and is light enough and bright enough to rival or exceed white for visibility and heat reflectivity from the shell. As an aside, the helmet I received was likely a prior return (part of the box was missing), and I am fine with that. I think it's a fair trade-off for being able to exchange my original order for the larger size. ... show more

  • Chin strap too short
Color: Matte Ano Blue Size: Large
Overall it is comfortable for my large, elongated type head and is the only helmet I've ever tried that feels like it will stay on during a fall without the chin strap being buckled. I chose this helmet because of its top rating in the Virginia Tech helmet rating charts, and i do not regret the purchase. However all helmets are meant to be work with chinstrap buckled and this one is about an inch too short for me to be fully comfortable. It will likely not be an issue at all for people with medium and small heads, but for me to give it a 5 star rating it would need an extra inch or two of strap. My previous go-to helmet is a Align II MIPS which cost $50 and had no problem with the strap length (I still highly recommend this helmet as well as the Giro) Other than that the helmet is lite, comfortable, well ventilated, easy to adjust. The liner seems to have a lot of slip to it compared to traditional MIPS, which i think will allow for greater damping of the concussion forces in a fall, which I'm guessing is what led to this helmet getting the top spot in VT ratings. ... show more

  • Giro Aries Spherical Helmet
Color: Matte Ano Blue Size: Large
It comes with good design and manufacturing standards. The ventilation is so excellent while it offers Mip protection. I find it is a kind of professional equipment and fashionable bike helmet though its price us on the high end.

  • All good except two things
Color: Matte Ano Blue Size: Large
This helmet is great and I really like the blue color. Just two problems for me: the wire for tightening that runs right above the ear hits the top of my ear and would cause a lot of irritation wearing over any extended ride. Went with a Lazer helmet that has a different tightening design and doesn’t get close to my ear. Other thing was a slight feeling of pressure on my temples. I have a slight larger head, and I guess my ears are set slightly higher - I can’t wear a number of helmets due to the ear issue, including some Giro and Bontrager helmets I’ve tried. ... show more
