Thats eVent material, nothing else beats it, and if you do a lot of research, you'll see that its pretty much an undisputed fact.
Then form it into a cycling specific jacket.
Pearl Izumi, Showers pass, and Gill, are the only 3 cycling jackets I can find made in eVent.
Then dont rely on the material to do all the breathing, but add as much venting as possible. Pit zips, open cuffs, back vent, 2 way zipper, etc. Of the 3 manufactureres I mentioned, Showers Pass is the ONLY one to add venting. And the PI one is even more expensive, go figure...
So there you have it, the best cycling waterproof made

A softshell made with say Schoellar Dryskin Extreme is prefered when its not raining. Its the most breathable of all softshell material.
And then use either the showers pass, or get a propore (raingear O2) as a storm shell to use over top.
The problem with the Propore ones is they tear really easy, so are sorta an emergency use thing to keep in a pack if you cycle in predominantly non rainy areas.
But if your looking to just buy the best 100% waterproof cycling jacket and be done with it, get the Showers Pass one.
