I've got the non-breathable pants and the breathable rain jacket. I wore the pants through our 50 odd day rain streak earlier this year, and never had a problem with them hitting the chainrings. Ironically, since I bought the breathable rain jacket, it hasn't rained during my commute. But I've worn it on some cloudy days, and haven't been sweaty at all. My previous jacket was a performance non-breathable number and I was always soaking wet from sweat.
