Mimi, arm and leg warmers are important for rides in which the temperature changes a lot over the course of the ride. Where I live, we can start a ride in the 50s, and end it in the 70s, so you need them to start and peel them off at the rest stop. LIkewise, when I toured in chiapis we'd need them early and late in the day but not in the middle. I agree, if know the temperature won't go above 60 I'll just wear tights, cuz I think they are more flattering, but the key to keeping leg warmers up is tucking them under long shorts.
