This has been my helmet for the past 3-4 years and it is very comfortable!! It fits well with my Oakley Airbrake and Flight Deck goggles! The adjustable venting is great for those warm blue bird days in March out West!!

Pros: Great ventilation

Would you recommend this product to a friend? Yes

I’m always warm and the vents in this helmet really work to regulate my temperature. I love the fact that I can close the vent at the top of the run and then adjust the vent when I am standing in the lift line. On really cold days, I close the vents and wear a light balaclava and I am fine.

Ridiculously Comfortable

Pros: Adjustable vents + size
Cons: I wish it came in more colors

Would you recommend this product to a friend? Yes

I've always been annoyed by helmets, but when I started snowboarding a few times a week, I realized I should probably be wearing one. This helmet is ridiculously comfortable, mainly because of the adjustable size. I can wear it with a beanie or without one and my goggles fit perfectly with it.
