I've had a pair of those for a while. I have a few of the unlined as well. They do hold up pretty well, as well as anything else. The crotch is roomy enough for all but the most extream maneuvers. I pulled a hip flexor a few months ago and haven't been able to heal it completely yet, so my flexibility is way down from where it was and I am now not restricted by wranglers at all... until I get all of my flexibility back anyway. I bought a pair of not too puffy downhill ski pants this year for the wind resistance. They were expensive, but the wind resistance is so so so so nice on windy sub freezing days up in the trees.
