Too cold and breezy for a real winter.

  • Familiarity: I've put it through the wringer

The cloth vent covers on the inside of the helmet are useless when it's really cold, the cold air just blows through. In the early spring when there is melt water from the lifts dripping down on your helmet, the water goes through the cloth vent covers and you've got a wet head. Once you're at the top of the mountain you've either got ice in your hair if it's freezing on top or you get a really cold head as you blast down the mountain. I had the older style helmet Giro Nine.NIne before this one, it had a rubberized sheet that plugged all the vent holes. I never once removed that sheet in ten years of use. I wouldn't buy another helmet with vents in, you don't need the venting, it's just a gimmick. I board 35+ days each season. Other than the vent issue, the internal sizing system works well.

I am looking to buy my first helmet, would this be a good option?

Hey Cody,

GOOD CALL! I resisted getting a helmet for so long, but now I actually hate riding without it. This is definitely a solid bet. Some things to consider when grabbing a helmet will be ventilation, audio compatibility, and weight. I personally love a helmet with a visor because they tend to fit a wider range of goggles, and you can prop your goggles upon them in between runs if needed. It will simply come down to personal preference. Happy shreddin.

Definitely get a helmet, it's not you but someone else that will cause you to go down hard and smash your head. Go to all the sports shops in your community; close your eyes and try on every helmet you possibly can. Then buy the one that feels the best on your head, irregardless of the colour or what your friends are wearing. Avoid vented helmets unless there's a mechanical vent closing device. I've wouldn't recommend the Giro Ten.Ten. I've been boarding 15 years, 35+ days per season.

Each helmet fits differently. You really need to go to a store and try them on first. My husband tried on 6 different helmets and some had gaps between his helmet and ears, some didnt fit right with goggles on. On a different note, my kids and i have giro helmets and we love them.

Very Comfy & Secure

  • Gender: Male
  • Familiarity: I've used it several times

Used this on a 5-day trip to Japan, and it's a very comfortable and snug fit without being too overly tight (I'm wearing a Medium for my 58cm noggin). As for the vents being "adjustable", you can't do it on the go... i.e. you've to take it off and adjust the flaps attached to the helmet liner to block or unblock the vents. Not an issue for me as I have the flaps out to block the vents most times and I don't overheat. Overall, this helmet's good enough for its intended purpose.

Good Enough

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

Bought this Helmet on sale thinking it was the same Giro helmet as my last (which I was thankfully wearing when I landed on my head and suffered a concussion). Unfortunately, the vents don't open and close like my first helmet. Unless I'm missing something the way to open the vents is to remove the fabric/material inside the helmet versus my other Giro helmet had a simple lever you could move from one side to the other. it does the job it's supposed to so I guess that's good. Wish they would have been more clear about how "adjustable" the vents were...

Comfortable but enormous

  • Gender: Male
  • Familiarity: I've used it several times

This isn't a bad helmet. I'm sure it does what it's intended to do, and luckily I've never had to put that to the test. My complaint is how stinking huge this thing is. You will look and feel like a bobblehead.

On the plus side, it's highly adjustable. It's comfortable at first, but the ear covers start to hurt after a full day of skiing. Don't depend on the back adjustment to make up for an oversized helmet, though. If you're in-between sizes, I'd recommend you find another helmet.

Like Eric, I found this helmet aesthetically wanting. It's a fine entry level helmet for the price (esp. if you can nab it on sale), but it just feels really bulky and I found myself wearing it less and less. Also, if you have longer hair it does tend to get caught in the helmet liner material from time to time...

Good entry-level helmet

  • Gender: Male
  • Familiarity: I've used it several times

This is my first ski helmet, and I feel it is good for what it is: an entry-level helmet. I bought this during Black Friday and for the price, I'm very happy. Yes there are better helmets, but at a higher cost. You get what you pay for, and I feel this is a good value. I agree with some of the other posters about the annoyances adjusting the vents. I've gone skiing with it 5 times so far, and it is comfortable enough and has protected me. I recommend you try this on in a store before ordering, helmet sizing can be tricky to find the right comfort level.

The circumference of my head is almost...

The circumference of my head is almost exactly 55.5cm. Would I be better off buying the Small size or the Medium size?

If your head is wide side to side then go a size up...otherwise I suggest taking a chance with the smaller size.
