These are simply the toughest and most comfortable pants I own.  I was in the service for 3 years and got very used to BDUs and dreaded going back to regular pants in civilian life.  I purchased 3 pairs of these and all three pairs fit like they were tailor made and have held out very well.  The color has faded slightly due to extreme use and I will say that the zipper fly can be problematic because some of the teeth on each of the three pair i have are just slightly out of alignment and the pants must be pull up and perfectly inline to get the zipper to pull up.  Plus the zipper is metal and gold in color which is terrible if you are actually doing night missions.  For civilian use they are simply the best.  A+++ Highly recommend
