For cold and/or snowy weather, really loving my Mountain Hardwear Winter Wanderer pants. they fit, stretch just right and are quiet. After wearing them once, bought a second pair. They have relgated my early version of Sitka Gear pants to distant backup.
Alas, MW stoped making them. The replacements are the Yumalinos, when I checked them out on the at the store they look and feel just like the Winter Wander.
