I agree with buetilo and Curtis,
Headsweats are great, and they come in different colors so you can coordinate with your jersey color.
I'm still waiting for Curtis to introduce the 50+ headsweat in the same color as the jerseys and shorts, and with the 50+ logo. Guess that will be after the socks . . .
Regardless, headsweats (and similar head coverings from other brands) work well, and I pretty much don't leave on a bike ride without them. I even use them over my wool balaclava in the winter (like today).
