Finally- a helmet that fits
- Familiarity:

Was searching for a new helmet to replace my aging Specialized Prevail II Vent. I tried probably 5 different brands and multiple models from each before I found a display model in store of the Giro Aries to try. This fits very well, has good shape, and feels secure. The reviews about sunglass docking are true. Still trying to evaluate the airflow but it has been 90 deg and 80% humidity lately so there is no stopping profuse sweating. I was pleasantly surprised that Giro included a spare sweat pad in the box. Nice touch. Happy with my purchase!

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.

Hesitant to buy but couldn't be happier!

The cost was a little prohibitive but I finally jumped when Backcountry had 20% off full priced item. It's an absolutely gorgeous helmet and so comfortable. I measured 23 inches and went with medium which was perfect. I've only worn it for a few spins but in love.

Very comfortable well made helmet

Extremely well made very comfortable with a few great features like removable sweat bands, and easily adjustable straps that really make it well thought out and enjoyable to wear. The ratcheting fit system works like a charm and I can easily adjust the size depending on the weather to fit thin beanie for the cold mornings of northern Washington. The spherical system is interesting and thankfully I haven’t needed to use it.

I"ve had this helmet now for a month of road biking. First - I"m a sweaty dude. There is a steady stream of sweat rivulets flying of my vapor trail as I cycle on any ride. With that background, a few comments in key areas: Price: ouch. It's high. But.. a hospital bill and a significant head injury is much much higher. I trust the VT helmet ratings, and the technology here makes sense. It's an investment. Cooling: superb. Lots of airflow through this helmet. It's got a very streamlined design, thus no mushroom effect. This design likely opens up the airflow quite a bit. Looks: see cooling comments. Looks super. Not a massive helmet to make me look like more of a doofus than I already am. Aero: Hard to say. But really, doesn't make that much difference unless you're going to shut down the airflow to go full-on aero. Sweat Management: school's still out on this one. For sure, it's not worse than others.. the question is whether the gutter sweat management headband really is up to the challenge of me. Based on a month of riding, I can say it probably helps, and again doesn't make things worse. And hey, if sweat reduction is less on the lenses of my sunglasses then there is crash reduction... see notes above about crash head injury investment. What I can say for sure though is that "at least someone is trying..." to help us sweaty guys out. Thanks! Sunglasses management: key. I read one review where someone was ripping on that. No... the purposeful sunglass arms slots is at least a nod to trying to make something work instead of a random possibility that it'll hold my glasses. I have oakleys and I also have an Italian brand. Both work well. And really, this is more a function of the flexibility of the glasses arms and the width of the glasses more than it is of helmet design. Regardless, thumbs up in this category. Summary: double thumbs up as long as you can tolerate the investment. My last crash co-pays medical were in excess of 3k, so ya - easy investment for me. Sizing: true to size for sure. Follow measuring process for sizing and you'll be fine. Last comment : Love the blue color!
