I picked up a one-piece Aerostich Roadcrafter R3 suit, and I'm blown away. The quality of the material is top-notch and the ease of which to put the damn thing on is really fast. Also, the ability to have it custom made to your size requirements is awesome. Yesterday, my commute home (50 miles) included a lot of rain. I was kept completely dry, even with the back-flap unzipped and the arm-pits. I can't talk highly enough about it. The only drawbacks that come to mind are that it is (1) cost prohibitive ($1200+), and (2) it takes 5-6 weeks to have made and shipped.
