I long ago gave up on the idea of raingear per se. Most of the stuff out there is expensive and doesn't hold up well, or at least well enough to justify the cost. So I wear 30gal trash bags, with neck and arm holes cut out. I keep spares both at work and home, and if I have doubts about the weather I can carry one with me rolled up.

I use better rain gear in the winter, but in cold weather, it does double duty as insulation and a wind stop, but that's too hot when the temps are above 64 or so.
