I obviously can't attest to the durability of these pants... yet... but the initial fit and feel are excellent.  I'll be using these for casual wear, yard work, hiking, and trips to the flying field during the cooler months.  The number of pockets are a real bonus, especially the pocket for my cell phone which is just snug enough to hold it securely.  The waist hits me just where I need it to, so I'm comfortable all day.  If I my expectations are met on durability I will be a Carhartt customer from here on out.
