***EDIT*** I somehow placed this in the wrong forum, apologies.
I know there are some folks on here who have spent time as hotshots or wilderness firefighters. I have seen various USFS issue nomex pants at thrift stores and the like, and I've always wondered about how they would do as general use backcountry pants.
The pants I have always seen are the standard USFS green, which look an awful lot like BDU pants, but recently I've become aware of a whole slew of aftermarket pants which offer improved cut/function over BDU pants (gusset crotch for one).
Of course, the price is usually pretty high, but not outrageously so for a US made garment. I also like they they are offered in standard waist/inseam measurements. For backcountry use the nomex is not needed of course, and I am not sure how it is as fabric breath ability wise, etc...but maybe they would do OK?
