In the military some guys would buy Gore Tex steal suits, usually $50 for a jacket and another $50 for pants and wear them under our combat uniforms. Extremely breathable, waterproof, and quiet as the name implies, it's simply a Gore Tex layer.

I didn't really like the new CF issued Gore Tex gear because I found myself over heating too much in it. Otherwise the US Army surplus Gore Tex gear is also good and very cheap.
I don't recommend Gore Tex for cold weather however as the material is too breathable and you will get cold.
