I used to wear tights, best thing since sliced bread, I never had chaffed legs and they seemed warm, my mates, used to laugh, but then they wore them, and have done so ever since.
( before you start to think I've done the other way,) I used to work with horse's, and I was riding almost all day, and would get saddle soar...and they do help to stop most of the chaffing on your legs,
