I've got a pair of Gander Mountain zip-offs that I got at Sierra Trading Post almost twenty years ago. They have held up remarkably well--I think I paid less than 20 bucks for them. I also have a pair of nylon warm-up pants that came from a thrift store for not much; they are pretty warm and I have used them around camp for a good many years. I second Shug's suggestion--try some things and see what works for you. Ask other folks when you're out there hiking. You don't have to spend a fortune or have any brand names on things to impress when you're heading for the woods.
