3-year update:

I've got 4 pairs of these that I wear most days that I'm outside (which is most days) and just bought another few pairs. These wear like iron, and while they fade over time, that's not really obvious until you buy new ones.

These fit like Levi's jeans in the waist and crotch.  My 36" inseam pair -might- have been a little long, certainly not too short, which is a frequent problem for me when I buy pants.

Everything about these pants is well made and either heavy duty, reinforced, or both, but these pants are still comfortable to wear all day and they have plenty of room to move around in.  The zipper is a burly YKK unit that will never fail.  One of my favorite features is the "double" right pocket.  I like it because I can put my phone in the inside pocket all by itself and not worry about it getting banged up by whatever is in the outside pocket.  The waistband is one of the reinforced and heavy duty features.  I'm not a clothing construction expert, but this must be the stoutest waistband that I've seen on a pair of pants, and I'm pretty sure that I could suspend myself from the belt loops if it came to that.

One downside:  My high efficiency (front loader) washer mangles these pants.  I have to untwist and straighten them out before hanging them to dry.  They haven't been in the dryer.  They might come through O.K. But I'd be irritated if they shrank, which seems like a risk with these pants.  As I said, I'm no pants engineer, but I'll still hang these just in case.
