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.
