It really depends on if you're active. I hunted 35 years ago in jeans, even when cold - bad. I then had every known of wool pant/bibs known to man, for when it was cold. Not bad, if you're sitting in a treestand or something, but BAD if you're active all day. I used microtex a ton, for years, even when cold, with a good base layer under it. Not too bad - but not the best. I switched to an OR softshell pant a few years back and really liked that for cold weather hunting. Last year I picked up some Sitka Timberline pants. BAD ASS for cold weather active elk hunting!
