If you want to think outside the bun a bit - I did my sheep hunt up here with good gaiters, expedition weight long underwear, and SHORTS - quick dry nylon shorts. I had Patagonia's Rainshadow raingear pants to go over top - they come in a sagy green versus black for most others. I detest black, and I don't care for camo. I like the patagonia rainshadow product more than the Marmot.
For up top, I had a REI ultralight raincoat, supplemented by a lightweight poncho. Golite makes a good one. The REI raincoat is okay, but there's room for improvement. I'll probably try to pick off a patagonia match for cheap.
I'm still thinking all of this out, but there's more than one way to skin the cat. I'll likely go in next year with lighter longjohns and full pants - my current hiking pants are by mountain hardwear. In the past, i've worn REI's Mistral pants with great success. Don't get too hung on zip-off legs - the zipper and sewing adds weight and doesn't do anything for their ability to shed moisture...
