I use a skull cap (beanie) that absorbs sweat. It goes down a little lower than your average skull cap. Main reason I use it is to block wind out of my ears. I use it in almost any weather, except for when it's hot. It really makes a big difference. It allows me to ride as long as I want, as opposed to not having it on ... I'm only able to ride a couple of miles before the ear pain starts. I think I got it in the snowboard section.
