On my Wally versions.
Sizing: They run fairly true, maybe a touch big. Especially with how much stretch they have in the waist. Pretty slim through the leg, not unbearably in my opinion, but definitely slimmer than even the average outdoor pant in my limited experience. Not gonna be a look that a lot of dudes are used to, though potentially beneficial in an outdoor pant.
Durability: Stitching is terrible. Zippers are below average functionally, but haven't fallen apart yet. Material is good. I only have OR Ferrosi and an old pair of Mountain Hardwear convertibles that my wife has to compare to, but the material doesn't disappoint when compared. A little different, but not significantly.
Fleece lined: Haven't really had a chance to put them to the test, but they still have some stretch, lack of a thigh pocket on the one side bums me out, fleece is not stitched to the shell other than at the seams (dunno if that's normal for fleeced pants), warmth is decent as far as I can tell.
Summary: Great for the price. I'm still in the market though. Not certain how I feel about the slim fit. I see the benefit of less material (weight and noise savings), and have gotten used to it, but not sold on the "look". I'd gladly pay $40-60 for a similar pant with better stitching durability (OR, Mountain Hardwear, or Prana perhaps?). If I go to something 100+, multiple features would need to stand above (DWR, brush panels, hip zips and/or camo, etc).
