Nothing wrong with 5.11....to be fair,I hunt the mountains of central Idaho and I wear the bdu pants and shirt I was issued in basic training in 1998 because I'm cheap.I use long Johns a vintage wool Filson coat that was my great uncles.Duluth,prana,scent lock are all fine choices.Look at your budget.Layering is always better so you can adjust without overheating.....at the end of the day it comes down to comfort,warmth and durability.My hunting buddy has expensive scent lock pants,we both killed the same deer and elk together this year.So did our freind in town who wore blue jeans.
