I made myself a cloak/cape out of oilcloth that has a very muted Black Watch pattern to it. I cobbled it up to use at the Rendezvous and reenactments, but I've worn it on other occasions when I've had to pipe in the rain. Comes to about mid calf, and has a shoulder cape and collar, but no hood. Keeps most of me dry. Of course, being a reenactor, I've learned to resign myself to the fact that when it rains, you get wet.
