Genuine Dickies Men's Relaxed Fit Straight Leg Painter Pant

I work outside doing grounds work. The first time I bought these pants, I had 5 pair which I wore weekly. They lasted almost 3 years of that abuse! Where they started to wear at the knee and the back pockets were pulling from the pants. For what I throw at them, I can't complain about longevity or staining what so ever. Yes, they would get stains when I did harder jobs, but with some effort (running oxyclean and color safe bleach and sometimes baking soda) really helps and brings them white. I have definitely been asked before about them, since they are so white even when they were obviously aging and starting to show their age. That said, I bought Dickies "men's professonal painter pants" back in 2/2013 and they were tearing out the knees within a year. Those are 100% cotton, while these are polyester/cotton blend. I feel like the cotton ones were thicker and heavier, which I didn't like so much. I like these pants, so I just bought more!
