I have been wearing these pants for work multiple days every week for about a year. And went with me as my primary pants on an Idaho elk hunt. They are unchanged beyond some wear (pilling) on the upper thigh section. I work for a company that moves pianos and gun safes. These are by far the toughest and most comfortable pants I have worn yet. The stretchiness and temperature controlling design are a big asset in my line of work. My only complaint is the cargo pocket being on the left leg when I am right handed. Put it on the right leg or remove it completely.
