I find the underlayers are just as important to wet weather comfort, that some good ventilation and materials that handle wet well. I prefer water proof if out for extended periods. There are some nice breathables that are comfortable in some moisture, I have a Patagonia, Rain Shadow Jacket, nothing fancy but is light and has held up for years, easy to carry so you have it when needed. IIRC it was a component of the MARS System...
Stay dry
