For the last 18 years, I've had two Aerostich regular one piece Roadcrafters, red for conspicuousness. Not totally waterproof in heavy, day-long rain, which is why I keep a dedicated rainsuit in the panniers. Last one (8-year old) is horribly sun faded and dirty in spite of yearly washing and treating with either Scotchgard or Camp Dry, plus UV Tech. I had to add metal snaps to the collar and breast pocket velcro to keep them closed. Now the ankle velcro isn't holding anymore.
I'm seriously considering First Gear Kilimanjaro jacket and First Gear HT overpants. Reasonably priced and seemingly totally waterproof. I've seen only good reviews about them and absolutely no bad review.
