Excellent all-round helmet

Very comfortable fit. #1 on the Virginia Tech safety scale. Nicely adjustable. Good ventilation and aerodynamics. Compared against other top helmets. This one is more and more easily adjustable than the Lazer, though not as light. Liked it just a hair better than the Specialized. Slightly more expensive than those alternatives.

The helmet is light and airy, not much for wind noise. The inner harness pinches the back of my head at the top edge of the ratchet strap (may be residual swelling from last crash that made me need a new helmet), but I notice it less each ride. There is an inner fit adjustment on the inside that helps a lot for accomodating head shape. Came from a Smith Trace MIPS that very likely saved my life to the top-rated safety of this Giro. Loved that helmet too.

Got hit by a car wearing it

I don't think I can endorse this helmet more strongly. At the same time I was turning left, a car decided to pass me on my left (in a no passing zone of course). I was flipped up on the hood and "starred" the windshield of the car with my helmet and head. Other than a solid concussion I didn't have any significant brain injury. With a less quality helmet I'm not sure I would have had the same outcome. I purchased it because of its ranking on the VT website. I recommend reviewing the Virginia Tech helmet rankings prior to purchasing helmets. Stay safe out there.

Aries Spherical poorly packaged

This helmet has received raving reviews. I just received it and the MIPS cage was bent and broken. That component seems really flimsy and cheap compared to other MIPs designs or other Giro helmets I’ve used in the past. The packaging doesn’t help the matter either because that back bottom part of the head cage which was bent and broken, gets pushed down against the box. Hmm. I would consider just replacing it but since I now have to pay for returning it, + having to pay more to replace it, etc., I think I’ll have to pass on this one.

Great, nice looking helmet

Not too much to say. I like the look of it. It's comfy and easy to adjust. There's also a red flashing light that you can get (not included) that fits into the rear of the helmet, which is a nice bonus safety feature.

Very nice helmet with a critical flaw

Familiarity:
I've put it through the wringer

Lightweight, highly ventilated, comfortable, fits great. But they didn't design the vents in such a way that sunglasses stay in place when you want to slot them in to the holes. I've tried it with several different glasses and they fall out if you shake your head at all or if you bend over to get a bottle, adjust your shoes, stretch, etc. I've lost sunglasses out of the helmet while riding. It's pretty important to be able to put your glasses somewhere besides your face if they're fogging up or getting sweaty.

Great helmet but be sure it fits your he

The helmet fits great and looks good. The only issue I ran into is the MIPS cage that goes around your head sits low in the back just below the base of my skull so after a while, it can put pressure on that area and can lead to a headache. Think of someone taking their finger and pushing into the back of your skull. After two rides I was able to find the right combination of tightness of the helmet and my glasses location to make it work so the helmet now rides correctly and is supportive.

Comfortable Helmet

My previous helmet was the Giro Aether, which was damaged in a crash, so I needed a new helmet. I bought this one because I liked the Aether a lot and the Aries has the best rating in the Virginia Tech testing. It fits very well, is comfortable and ventilates well. It's pricey but for my money it's worth the price, both from a day to day functional point of view and from a safety point of view

Very happy!

Familiarity:
I've used it once or twice and have initial impressions

Two rides in, and I’m very happy with this helmet. It’s incredibly lightweight, well ventilated, and fits great. I tried a couple of different brands/styles looking for va higher end helmet and this just felt right immediately.
