About Giro
Working late nights in his garage, designer/bike racer Jim Gentes created the first lightweight adult cycling helmet in 1985. Friends at NASA helped tune the final helmet shape and vent placement, and the result was the Giro Prolight, a helmet that was better looking than traditional designs while offering a superior fit and still met the industry's toughest safety standards. Plus, it was half the weight of traditional helmets. Since then, Giro has advanced its helmets, many of which have set the standards for styling, function, and innovation for progressive, performance-oriented riders on dirt, pavement, and snow. Giro helmets are worn by millions of riders, cyclists, skiers, and snowboarders around the world. Young-bloods and old-timers; hard-cores, heshers, and hipsters; rookies, experts, and a few regular Joes too--in fact, pretty much anyone that appreciates superior fit and function, cutting edge styling, and the very best ideas you get in a helmet.

I use this helmet as my daily ride helmet to go to work. I haven't had any issues riding in 85+ degree days, as the airflow is adequate, although it isn't quite as good as some other helmets I have worn. The helmet ships with a variety of pads you can use to adjust the size, and the xlarge fit perfectly after adjustment, which I was concerned about as my head size was in between a large and extra large. The best feature has to be the excellent head protection you get with this helmet. The entire side and back of your head is covered so you can be confident you'll be protected in any kind of accident.

The helmet is awesome. It fit like a glove without needing adjustment, looks great and is very comfortable. The straps hold it snugly, and it doesn't shift. It is also very light.

It fits quite snuggly. I got the matte black and it scuffs like crazy :( I set it down and next think I know it looks like it's scratched from here to Timbuktu, but hey, it still works. The scuffs don't rub off, that's the complaint.

Size: MediumColor: White Verified Purchase
My head measures a little more than 23 inches around (more space for brains!), and so while I fit the requirements for a large, it was way too big once it arrived. Amazon provided a delightfully easy return service, however. If you're on the cusp between two sizes, take the smaller size.

I just got my replacement in the mail yesterday, so I haven't had the time to test it out. It seems to fit well, and looks nice. I will say, though, the medium size has some kind of glossy design imprinted on the matte finish of the helmet that I'm not crazy about. You can't see it if you're more than a foot away, but it wasn't advertized, nor was it on the large size.

I was looking for a bike helmet that was better made and differently styled than the standard bike helmets out there. This is a nice, multi-sport helmet that is heavier than a standard bike helmet so not the helmet to buy if weight is an issue. It's also a little hotter inside this helmet than a standard bike helmet but that is to be expected from this type of helmet. Appears to be made from higher quality materials as well. I agree with the one negative review, huge disappointment in the color. I couldn't see most of the reviews very well since I ordered this on my mobile. I bought the Matte Olive and the color is definitely more of a charcoal color and you might see the faint iridescent green in bright light and you strain to see it. Nothing at all close to the photo. Also, no size chart? I have 21" head circumference and bought the medium which gives a comfortable, not-too-snug fit.

Love it! There's nothing riskier than buying a helmet over the internet -- especially when you're sort of an over-endowed cranial mutant. But I found nothing that fit at the bike shop and the first helmet I ordered on-line cramped my cerebellum something fierce. Giro saved my skull! Added attraction is that it's comfortable, looks good and the color is truly the true-blue it appears on the page.

I have a large head and this bike helmet fit perfectly. It makes me feel save traversing the streets of Sacramento and (since I often bike to and from work and social functions) it is also very stylish. I was easily able to mount a bike light to the top for use after dark (the one on my bike was stolen and I vowed never to do that again). It is breathable and quite comfortable.
