I am a sweaty git, and got one for my Alps trip this year - no sweaty dribbles in my eyes at all!!. I have a big head - the large size with the smallest pads works really well. The helmet hugs the head, and holds position for headcam/headlight really well.
I got a really cheap deal on the Sabine Jonnier (sp?) women's version. I covered the silly balloon d
Graphics with black heli tape, and now I have an all black stealth version!!
Buy online, if it doesn't fit, send it back!!
It does also give significantly better coverage on the back of the head than my old helmet, and is very light!
