I wear glasses so I thought about a helmet like this so I wouldn't have to take off my glasses to put the helmet on. I looked at this and thought there was nothing to keep this thing closed if my face hit the pavement so I went with a Scorpion EX0-700 full face helmet. Maybe now you can answer the question I never asked before. How does the helmet "lock" in the down position?
