I have the wrangler pro's, a pair of browning upland pants and the latest is the Cabela's extreme upland pant.
The Cabelas pant is fleece lined, so it can be warm early in the year, but otherwise it is great.
I have been using them for all my hunting the past 3 years, deer, elk, and a ton of chukar miles.
Excellent water resistance, my brownings and my wranglers would get so heavy when they got wet it was the main reason I turned to these, which while not totally waterproof, they seem to resist becoming logged.
