I currently have the North Face Freedom pants, but the fit is a little off and I don't like the somewhat limited range of motion. Can anyone recommend a great pair of ski pants with good range of motion (including enough room in the hips/thighs and articulated knees) that would be good for mostly resort skiing, but some backcountry (as well as in-bounds hiking)? I would prefer styles with a solid belt/adjustable waist since I've found it hard to get pants to stay up consistently. My waist is smaller than my butt/thighs and I'd rather have enough room in the latter and be able to cinch down the former. Thank you!
