My experience with rain pants have been awful - as in I really, really hate them. They always seem to stick to my skin, and I hate that feeling. Once I realized that, I switched to just wearing tights in the rain as an extra layer.
I do end up riding in the rain sometimes when I tour though, and I was fascinated when I saw some info on Rain Legs, so I went ahead and ordered a pair. Unfortunately, they are still sitting waiting for a rainy riding day.
But here are links to a review, and to the manufacturer's site. They are not currently sold anywhere in the US. I ordered my directly from the manufacturer in the UK, and had them in my hands in less than a week.
