I have worn these Carhartt jeans virtually every day, all day for work. They are the most comfortable jeans I've owned. They show almost no wear in key areas that normally will fail pretty fast. Where"

I wear a set of keys outside my front pocket, every day, 5 days a week. The keys number about 20 and most sit outside the front pocket, moving every time I take a step. After a year, you cannot tell what side of my jeans I've worn the keys on, yet I wear them on the same side every time. Thats a tough test.

No wear on the knees, on the seat or at the crotch. No thinning anywhere. I think they last longer than the jeans I used to buy at The Gap and wore for the same purpose. Carhartts last. I have just a little color fade after a year, but I think they will still be in one piece after two years of solid, heavy use, occasionally crawling in and out of machinery, getting a workout.

Nice jeans, worth every penny cause they last and are comfortable.

Update August 2016: Still wear these to work every week. No complaints.
