I'm with Bryce, but with slightly older gear. Okay, much older.
But I also use mid- to heavy-weight polypro with nylon or nylon blend pants on top. No Goretex, because it won't rain for another 4 or 5 months and uncoated is more breathable than anyone's "waterproof / beathable"
My Patagonia Baggie Pants, (the long-version of their Baggie Shorts) from 1984 still work great. They're about 50% nylon, 30% poly and 20% cotton. If I expected a drizzle or wet snow, I'd go with 100% nylon, but that 50/30/20 blend isn't so coarse feeling nor as static-generating as 100% nylon. And it's really tough. Had a companion take a fall with metal-edge X-C skiis and break the skin and shave some hair off his leg THROUGH THE PANTS and yet, the pants were undamaged.
I like the combo because it's a combo and I can mix and match if conditions or exertion level changes. It's also been part of my no-sleeping-bag, week-long, high-altitude summer trips (nights to 35-40F).
