When I take off a Headsweats at the end of a ride, it hits the bench with a soggy plop.

If it's really hot, I'll just squirt from the waterbottle through the helmet vents, and the genuine cold feeling from the water lasts for probably 10-15 minutes. The Mission caps (I've found) are much cooler overall than others. Halo do indeed funnel the sweat away from your eyes, but they also seem to make a lot more of it.

I also take one of the Mission cooling towels (the kind that you wet and snap) with me when I know it's gonna get hot, and those are a miracle. I put it around my neck and it stays cold for over an hour, even in +100º weather.
