If "exposure" is the issue, you could always go with knickers instead of shorts. Granted, they may be a bit warm to wear in the summer...but I've actually worn knickers when the temps started out cool and then rose into the 70's and I felt fine in them. I particularly like the one pair of Shebeest "pedal pushers" knickers...they're cute, comfy and they don't have any grippers on the calves...they have a small slit at the calves. I think REI carries them.
