Law number 1: Land on your feet, not on your head. Should you violate the law, you'll be glad you're wearing the Giro G9 Helmet.

The G9's freestyle inspired looks and state of the art protection helps give you the confidence to stomp that new trick you've been working on. The G9 Helmet's impact- absorbing foam liner takes the brunt of huge impacts, so your brain doesn't have to. The tough polycarbonate outer shell will take multiple seasons of small hits. Once you get tired of the park, hike the ridge for some freshies. Giro gave the G9 helmet 12 vents to keep you cool and comfortable on the way up. If the temperature drops and the wind picks up on top, plug the vents with the included Weatherstrip vent plugs. The G9's ample venting and light weight make it an excellent choice for backcountry riding as well.

Great helmet

Light and comfortable. Use it for skiing in the winter and biking in the summer. Love it.

Lifesaver--and super comfortable

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.

Railed myself on a tree at Brighton, was charging hard and flew headfirst into the tree at high speed. Hit it harder than I ever could've imagined but I skied away after a short recovery. The helmet may be broken, but remember, that would've been my skull without it.

Saved my life

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 thinking I should take a size Medium. I measure 22" or 56cm. I heard someone with a 57cm head took a small because the medium was too big? Also I am trying to decide if I should get this helmet or the K2 Moxie. I know the G9 fits my head shape. I don't know if the k2 Moxie fits the same size head shape? Thanks alot.

Best Answer Responded on

I would recommend this one in a medium. The Moxie actually runs smaller, with the size medium fitting a head size of 21-21.5". I would stick with this helmet in a medium.

I have a Giro 9 I got from my brother in law some years ago. Does anybody have an idea if I can get replacement pads for the inside?

Responded on

ask giro directly, you might have to pay a few bucks+shipping, but its better than buying a new helmet

The 9 is a 10!

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.

Tight on the ears. Try it on for a few hours.

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.

alright, bad goggle compatiblility

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

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 I'm very pleased with it overall.

Solid Helmet

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.

Nice fit.

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.

real Nice helmet for my wife

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 !!!

Def recommend!

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.
