The Nine.10 helmet is derived from the original "nine" helmet released over a decade ago, but has been redesigned to fit modern demands. This helmet has tons of vents to keep you cool when your heating up on the slopes but they can be covered on blustery days with the Weather Strip vent shield. The In-form fit system is an adjustable sizing system on the rear of the helmet so you can literally dial in the fit without a hassle. This helmet is comfy, lightweight and will get the job done!

In-Mold Construction: A one time industry standard, now In-Mold construction is viewed as the highest quality lightweight construction style. Helmets made with this method will be the lightest on the market.

In-Form Fit System: The In Form Fit system makes it easy to dial in a custom fit in seconds - even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6cm of adjustment and enhanced stability while the vertical tuning feature accommodates different goggles and head shapes for a custom fit, free of gaper gap.

Goggle clip: Two lateral guides that keep the goggles in place, and doesn't interfere with the goggle adjustment clips.

Safety Standards: ASTM F-2040-00: Meets the standard specifications of protective headgear for snowsports

CE EN 1077: This is a European standard that has performed testing on these helmets to ensure they function as designed, and that they exceed the minimum standards for snow sports. In other words, they dropped heavy objects on the helmets, and they didn't break.

Super Cool Vents: The vents on this helmet pull cool, fresh air into the helmet while pushing heat and stale air out. By maximizing efficiency and optimizing vent shapes, the collective cooling power of Super Cool vents helps regulate your core temperature and keep you feeling fresh all day.

Giro Lifetime Warranty: Yes, you read correctly. Giro stands by their product and will warranty any manufacturer's defects for the lifespan of the product. Pretty sweet deal, especially for goggles and helmets. Check out more here: for full details.

Weather Strip Vent Shield: Weather Strip Vent Shields work to seal off vents in extremely cold conditions. A Velcro tab secures the shield when not in use to allow proper ventilation.

Audio Compatible: This helmet is compatible with all aftermarket Giro Soundsystems. Unsnap the liner and drop the headphones in, its that simple!

Great HelmetReview by chris
This is the second helmet I buy in my life but the BEST by far. Level 9 have a fast service which I think it's great!
Would definitely recommend this helmet. (Posted on 3/24/2017)
PainfulReview by Max
I bought the large helmet (my head size is 59cm, so I should have room). It fits well on the head, but compressed my right ear. It is not immediately noticeable but started getting painful after half day of skiing and was barely sustainable after a full day. I tried several times to shift things around but without success.

Great for cranial endowed men (Posted on 3/16/2017)
Excellent - especially the service!!!Review by Mr. Rando
So, for the helmet; it fits, it's comfortable, and looks really sharp! Fits my goggle shape too. Just what I was looking for. A+

Now, lets talk L9 Sports: THEY ROCK! Best price anywhere for ski equipment. (I used their Low Price Guarantee - effortless transaction) I was totally blown away with their customer service. I called three times and each time they were awesome. Friendly, professional, knowledgeable. My item arrived in 3 days (yes, 3 days!) and in plenty of time for my next ski trip. THIS IS WHAT INTERNET SALES SHOULD BE LIKE. Right on guys and gals! Keep up the good work! (Posted on 3/8/2017)

Tried the helmet on in my local ski shop - checked price on Level 9 and saved $ complaints !! (Posted on 2/13/2017)
I Think it Worked.....Review by Headache
I noticed that there are no reviews on the most important aspect of the helmet......impact. I replaced my old helmet with this one, and on my very first day with the new lid, I had the chair safety bar slammed down on my head......hard (still on the ramp, what up with that...). No visible damage to the helmet, but a definite blow, and I sustained a concussion. I'm a bit surprised about the concussion, but I suspect the damage would have been much worse without the lid. Also a slight sore spot on my head which went away after a couple of days, but the concussion is not yet resolved (1 week). I think it did the job, and I ordered another one. Oh, by the way, yet it was comfortable and warm and I liked the vents. (Posted on 1/27/2017)
Good HelmetReview by Liz
This was my first ski helmet. I have never used one before, but thought it was time for safety reasons. The helmet was comfortable. I liked that the strap was adjustable as I do not like things tight around my neck. The weather was warm so I can not speak to warmth, but I think it will work fine when the temperatures drop.
I would recommend the helmet. (Posted on 1/27/2017)
very niceReview by Mr. P
I tied the Bern Brentwood zip mold helmet first and it seemed cheap and had a minor defect but wasn't all bad. The staff at level nine was great about the return and exchange. It is the staff that makes level nine a pleasure to deal with and worth coming back to. I then got this helmet the Giro nine. 10. The helmet fit great and looks good. The vents don't close, the head adjustment can have a small learning curve of 2-4 tries which is a surprise because I used rentals that were actually simpler to adjust but the helmet is actually very nice. Fit and comfort were spot on and adjustment is actually easy after a few tries. I would give this helmet 4.5 stars if I could and 5 because of the staff but I am not rating the staff and you can't give half stars so because of that coupled with the no close vents and adjustment curve, I give it 4 out of 5 stars.

Great helmet, great price. Review by Wood
Got this for the special Christmas price. Great helmet for the price. I should have bought another. (Posted on 12/24/2016)
Gets the job doneReview by Nick
Not super comfortable but adequate. Vents do close using flaps inside lining. The small duck Bill in the front makes it hard to put your goggles up if you want to take them off. Not perfect but worth the price (Posted on 12/23/2016)

Vents not so coolReview by Dazza
As always great service by the L9 sports team but the helmet is a fair weather accoutrement at best. The "flap" system to regulate noggin temperature leaves a lot to be desired! Make sure your jacket has a hood! (Posted on 7/28/2016)
The helmet and price seemed great, but havent used it yetReview by Satified Customer
I want to compliment an employee at the store in Salt Lake. I didn't get his name. I picked up the ordered helmet and left the store right at closing. 30 min later I realized I had left my phone on a table at the store. We raced back to the store hoping someone would be still be there. A couple of cars were there and I knocked on the door. A gentlemen came to the door and said, "I noticed your phone right after you left but couldn't catch you." He said he had sent me an email and put the phone in the safe. I was very grateful for his help since I live an hour aay and it was a Saturday night. I would have been worrying about my phone for 2 days. It's wonderful that level nine has employees of his caliber. Thank you so much! I'm sure the helmet will be great as well. (Posted on 4/26/2016)

Vents do not close. In wet snow or rain your head will get wet. (Posted on 4/19/2016)
Great for hotties!Review by TheHumanFurnace
After discovering this helmet, I no longer have an excuse not to wear one. As someone who generates a LOT of heat, I really appreciate the well designed & excellent performance of the venting in this helmet. Totally useable even on a hot spring day in super sloppy conditions.

This was my first purchase from L9 & I was 100% happy. Standard shipping arrived one day earlier than expected, the product was well packaged & in perfect condition. GG L9! (Posted on 4/8/2016)

Helmet fits well and price was great.

But the best part of this purchase is the customer service provided. These guys are incredible! Easily accessible, ready to help, quick shipping, quick response to questions, the list goes on. DO NOT hesitate to order from Level Nine. You will not be disappointed. (Posted on 3/16/2016)
