I too am follicly challanged, and I use a Headsweats under my helmet pretty much all the time. It's usually just enough to contain the heat and break the wind on cooler days, and helps keep the sweat out of my eyes on warmer days. I might also add that is serves as limited protection against stinging instects that find their way into a helmet vent.....ask me how I know. When it's cold enough to warrent ear warmth, I swap the Headsweats for a windproof skull cap.
