I have 4 pairs of these pants. Originally, I gave them a five star review because the fit was perfect, they are comfortable, and looked nice. I have worn them several times and they seemed to be well made. However, I've changed my rating to three stars. I've washed 3 of the 4 pairs I bought. The black pair came out o.k.. The olive and grey pairs are not color fast. The olive pair faded considerably in the wash and has a definite brown tinge to it in the thighs and knees. The grey pair did not fade as much, but you can also see that brown tinge in the thighs and knees. I can still wear them as work pants, but I was disappointed. I have also noticed that the inside of the front pockets have excessive wear. The bottom line is that these pants do not cost much, but will probably not last long. Are they worth $30? Personally, I'd rather pay more and get better quality. I had put several other Goodthreads items on my wishlist, but now I'm rethinking that.
