I've never tried a helmet cover, but I wear a Buff cut in half when it's not too cold, a Buff folded in two down to about freezing (can cover ears or forehead as much as you like), and a Gore softshell helmet cap when it's cool+raining or below freezing. I like the cap a lot, not bulky but cuts the wind completely, but I can't hear a thing when I'm wearing it. I rode home yesterday with a friend of mine, and we were both wearing these caps, yelling at each other the whole way...

Winter riding is much less about badassery and much more about bundle-uppery. - malkin
