For cold and snow there are two choices - wool and the inferior stuff. High priced or milsurp wool pants work about the same: long lasting and warm when wet. At least 10 years ago I bought a couple pairs of milsurp from Cabelas for under $10 each and they're still in very good shape. The only problem was that they had button flies that were very hard to get buttoned. I installed zippers. They're ugly but I'm out there to get elk, not girls (I have a perfectly good one at home).
