Cabelas made a wader "jean" for a short period of time that were great. They're the bonded fleece, cut is great and work great over some UA coldgear. They also made some wader "pants." They aren't the bonded fleece, but since you can't find the jeans anymore, they're the next best thing in my opinion.
The drake bonded fleece pants are ok. Like was said above the cut on them sucks. If you don't wear pull them up to about tit high you'll tear the crotch out of them first time you step high over something. But they are warm and wear great.
Also gamehide makes a great pair of hushhyde pants. They're completely water and windproof, but will run you out of the house if it's not cold. I don't get to wear mine much because it's not really cold enough, but when I do, they're great.
