I bought this helmet b/c of the visor - hoping it would actually keep the sun out of my eyes; but that was wishful thinking, since it doesn't help with the low morning or afternoon sun. i'm still trying to figure out how to wear a visor comfortably under a helmet, and thought this would help. it hasn't. i also have trouble with it loosening up while i ride, and getting too loose. i may see if i can return it.
My favorite bike helmet ever. I got it based on a hardcore cyclist friend's recommendation and my head is thankful.
