The Wolfskin Germ mentioned from Gray Wolfis not touted as waterproof, but it's darn close. I wore it on my elk hunt in Colorado a few weeks ago, and I stayed dry through mild showers. It's especially effective for walking through the woods still-hunting when the foliage is soaked and you know anything cotton you're wearing would become so as well, but aren't in the mood to throw on a rainsuit.

I haven't ordered the rain gear from Predator's site yet; I'm curious to learn about it though if anyone's tried one yet.
