thanks for the info guys.
I guess I should have clarified what I meant by "no vents". I meant that it doesn't have several holes in the actual helmet like many helmets do. My current helmet has these holes/vents and it keeps my head pretty cool.
I didn't notice the vents under the visor when I tried the helmet on, but I read about the "Airvanced Ventilation" which is what I was wondering about. I assume those vents are what they refer to in the writeup on the helmet.
So, for those of you with the helmet, does opening those vents let a decent about of air in? The helmet definitely fits me the best, but I won't be able to test how hot it gets until I'm on the hill.
