The thing is...being wet AND in the wind is the real danger. Riding hard you're going to sweat. And I don't believe there really is such a thing as "breathable waterproof/water-resistant material. Even if it is "breathable" the moisture is coming out of your body faster that it can escape through the "breatheable" material. So, I choose an outer layer that will break the wind regardless if it's wet or not. So I get wet on my inner layers from sweating...at least I stay warm because the windbreaker keeps the wind from carrying my heat away.
