I am 5'10" and usually a size 18 or 20, depending. I was on quest to find sleeker pants for a winter trip. I hate the bulk of typical "snow pants". These are spectacular to avoid that. Inside and out the quality feels right for the price. They are definitely long enough, too, though I wish they weren't quite so boot cut. Slimmer would be nice. Typically my thighs are larger, proportionately, and these fit great. The waist was a little big, but the elastic/Velcro adjustable waist took care of that. I wouldn't have been able to go smaller and have the thighs fit enough to be active. Although we haven't taken the trip yet, from a fit standpoint, I would totally recommend.
