I bought a pair of these (not from backcountry.com, sorry!) pants over a year ago. I have worn them to class, hiking, camping, working in the cold, everything. They can withstand being worn for a week or two without needing a wash, gross but true. The areas of high use (around pockets, knees, etc) is fading in color but the actual material is still in great condition. The canvas is comfortable and durable to the point that you can most likely own a pair of these for years.
