I wear Wrangler-Riggs-Contractor-Dungaree-Duck-Pant, they are pretty tough, but the catch is I only pay about $8 for them from an outlet store that I drive past quite a bit. I just stop in and check for 32x36's and if they have them I by everyone they have, which is usually just 1-4 pairs. I really like them and for the price, I could care less if they get damaged, but for the life of me, I don't think, I have ever completely ruined a pair yet. I do have some that look pretty bad and probably wouldn't wear them to a church gathering or anything, but they still function for holding things in during rough and dirty work.
Here is a link to them.

I have pretty much quit buying Carhart, they are just too expensive for what they do. I can buy at least 2 of any other brand at a normal price and that other brand will usually provide a rough looking "pants/shirt/coat" and a modestly, good looking version of the same, for the same price as one set of the Carharts that will look trashed.
I'm all for quality, but at some point it gets too expensive and if in the end the higher quality unit looks bad or wore out too, whats the point of spending it.
My opinion,
Sam
