Familiarity: I've put it through the wringer
This is a great fitting, lightweight helmet. I've worn it on super hot days on high-mileage rides and never once felt overheated with it on. I definitely feel the chill through the vents on cooler days.
I really like the easy Roc Loc adjustment on this helmet - feels a little flimsy but it's fine as long as you're careful with it.
