I'm not sure how waterproof you want, but hubby and I have older versions of this. We don't usually ride in the rain but we insanely did the 40 mile loop of the Rice Valley Tandem Rally in them last year. We even paid our money after it had started raining, but you gotta see the rooster tails on tandem teams in a pace line in the rain!

Anyway, our upper halves stayed dry; I just shook my jacket at the end and all the road gunk just fell off. I was very impressed. It used to come in a bright yellow.
