I don't wear cargo pants. But I rock Mountain Khaki Camber 107 pants almost all the time outside of the office. They're comfortable, sharp-looking, and are 87% cotton canvas with 3% spandex for a bit of stretch. And they cost under $75 per pair.
I don't get excited about pants....until I got into these.
