I have three or four rain jackets. Still trying to find one that breathes. Rain jackets are sweat boxes if temps are not so cold; if I'm hiking and it's 50F or higher, I typically wear a poncho, or no rain gear at all. Otherwise I'm sweating so much I wet out my clothes anyway and who needs that.

PU coated jackets don't breathe at all, Goretex hardly at all - pit zips are better than most of the fabrics readily available in terms of preventing my inevitable wetness.

Lately I've started using an umbrella. It works for me pretty well in a lot of places. Probably not a great idea where there is a lot of wind (Mary Poppins I am not) and definitely not for bushwackery, but it's been pretty useful overall against sun and rain.
