My favorite rain/wind jacket of all time is a GoLite rain jacket. It's supposed to be breathable and "four layer". I don't see how, but it works. It's tissue paper thin, however its dry, tough, crunches down to nothing and weights practically nothing. It's withstood the test of time and has been all over the world with me for years. I'd buy another in a heart beat. You can still find GoLite stuff around on Amazon and Sierra Trading post.
