This helmet is awesome! It is super light--so light that it's never ever a chore to wear the helmet. The sliding vents work well when the temps rise. I've wiped out hard with this helmet--slamming my head against hardpack, a tree branch, etc. Fit is super easy to dial in with the adjustable dial system.

Fits well (I wear a beanie underneath). The new Dial a strap they put in as of last year helps with the fit, and when it breaks, you can just rip it out. The new ear flap mechanism is also nice, even though I took them off. The helmet has minimal gap with Anon Solace goggles. Rad! I wear it when i go cycling as well in the summer time as well.

My son said this helmet feels, great. He likes the adjustment dial, finding it very convenient, for great fitting. That dial will also allow him to wear the helmet through additional growth (he's 16). He notes the ear flaps are very comfortable. As he did not choose to do "ski team" this year, he does not need the rigid ear flaps. (Alpine Ski team required hard ear flaps.) He feels these flaps seem quite safe, and, again, finds them more comfortable than in has last year's helmet.

I searched the web over looking for the perfect helmet. I have always liked Giro for Mtn. Bike helmets, and that led me to purchasing their ski helmet. I have a large cranium, and the G9's adjustable sizing band allows for a snug fit with or without a skullcap. The ear pieces and chin strap are extremely comfortable also. In addition, the removable vent plugs are easy to remove and put in your pocket. I would always recommend at least looking at helmets at a local store, but then coming back to the web to get the best deals. This site and the Giro G9 were the best combination for me. I would defiantly recommend this helmet to everyone. Go Giro!

i got this helmet originally at a ski shop because it was an XL, and i have an XL sized head. I need to special order my lacrosse helmets too. anyways, it is really warm, but unless you are wearing a balaclava, the wind has a nasty habit of slipping in between my anons and the helmet. i combated the problem with rolling a piece of duct tape and putting it between the goggle and the helmet. its lasted for about 2 seasons now. other than that i love it.

apparently giro goggles fix this problem so no need for the balaclava or duct tape

This helmet does a good job. I previously wore a Giro G9 for about 3 years, and stuck with it. It's warm, and I like the helmet adjustment on the rear of the helmet (my previous version did not have that) that is similar to my cycling helmet. The only down side is that my Roxy goggles don't fit on the brim when not in use for some reason, and they're left to dangle and collect snow.

When I took a spill whilst charging through the trees and railed myself headfirst against one of the suckers, this helmet undoubtedly saved my life. Obviously, now it is done for, with a massive dent and considerable crack, but that would've been my skull if not for the good people at Giro. Thankyou muchly guys, I will be getting a new G9 to replace it without even considering another helmet.

(Also fits well with Scott Decree goggles)

I love this helmet. Vents when you want them, great fit, and good looks. I upgraded some speakers into the helmet and I couldn't be happier on those solo days on the hill!

I'm on my second one of these (last one flew out of the rooftop box on the freeway), and this one is better than the first. The ear flaps fit more securely into the helmet. I love the fact that it keeps me warm when cold out, but I can also remove bits to open vents/expose ears for those spring riding/hiking days.

As a first time helmet user this one is GREAT!
Just got back from wearing it on a week long ski trip in Jackson Hole and I didn't even know I had it on.
Super comfortable,no side visual restrictions,and my head did not overheat!
Five stars!

Great helmet. Fits great, and I would say it's a helluva lot warmer than just a wool cap, even though I keep take the vents blocker things completely off all the time. Would be nice to have a switch to open/close the vents instead of ones you have to take out yourself, but you gotta pony up more $ for that.

Super nice helmet. It's doesn't weigh much, and fits well. I was on the border between a small and medium and i went with a small. It fit perfectly.

She loves it, fits perfect, color morocco is a bit dull, could be a bit stronger red, but still ok. Keeps warm and breathable, I only missing a lever like at the "fuse" for colder days, then it would be perfect !!!

This helmet is a great all around helmet. It fits well, is warm, especially with the ear flaps, and fits goggles well with no gaper gap. The vents work well when not plugged. My head is never warm on super cold days. Simple and effective, just what I need in a helmet. Gives you piece of mind also.

Great balance of features/price. I especially like the ability to open the vent plugs for some air circulation for sunny days. The headband tightener is a great idea, but a bit strange because it pops loose when there's a back impact to the head...perhaps by design, like crumple zones in a car? It's already protected my noggin when I fell on my back...so I'm very pleased with it overall.

I bought this exact helmet at the first of the season and loved it. Covered my ears perfectly and i never once had a problem with it. I recently had a good crash and this helmet saved my brain from falling out on the snow. I cracked it in three spots in the back like it is designed to do on falls like the one i had. I am for sure going to buy another one exactly like it.

Great Helmet. Lots of micro-adjustments and very comfortable. I have Oakley goggles and no issues with goggle fit. Warmth was fine, but I didn't get into anything very cold yet. Pretty much the only thing you don't get (and don't pay for) is integrated headphones.

I strongly suggest you try it on for an extended time before it's too late to return it.

I originally purchased the matte black G9 in medium because it fit perfectly in the store. There was room for maybe 2 clicks of the adjuster. After wearing it for a couple hours I had to return it because it made my ears hurt like crazy. The pressure on the ears was too much for me. I got a large sized G9 and it definitely feels looser on my head, and I look goofier with the bigger helmet, but my ears dont hurt. Part of the problem is that I'm right on the border between M and L with a 59cm noggin.

Fits perfectly with my Oakley A-Frame goggles. No gap at all.

This is the first helmet I've owned, but it is definitely comfortable and gets the job done. An adjustable wheel in the back makes it fit snug on your head, there are removable vent covers which help to regulate your heat, and the chin strap is barely noticeable. However, I have a couple issues. First is simply a style point: the helmet is kind of bulbous/bulky and in retrospect I would have rather gone with one that has a sleeker cut to it, like one with a visor in the front. Second, goggles do not rest on the helmet very easily; they almost have to balance between falling back down on your eyes and falling back over the top of the helmet, which is frustrating for putting your goggles up in the tram/lift line.

Helmet is comfortable and keeps me warm. Seems sturdy enough, haven't fallen on it yet.

Ski season hasn't started yet so looking forward to wearing it.

The silver helmet is a women's breast cancer awareness helmet with 3 and 4 leaf clovers on the back. The backcountry people lied to me about the design on the back and now I am in the process of returning the helmet. The helmet could kinda be consider unisex but it just wasn't for me. Very comfortable otherwise and it fit snuggly.
