Brand isnt really the important thing, materials and construction are.
Brands like carhartt, Duluth, etc. make durable workwear, but a lot of people want clothes with the aesthetic of workwear, but in stretchy, soft fabric and slimmer fits, and those brands will accommodate that.
Duluth firehose pants, for example, are really durable. DuluthFlex firehose pants, though, look the same, but include 3% spandex. That means that the heavy duty cotton canvas is actually just held together by spandex, which wears out easily.
Whatever brand you get, just make sure they are 100% cotton, or maybe cotton/nylon blend. Something like wrangler 13mwz might fit the bill for you.
These pants don't have to be pricy, either. If you are shopping somewhere like rural king, tractor supply, etc, you can find pants like that for $20.
