Jean guy here: not all levi's are created equal. I own Levi 510's& 511's, they're really nice and fit really good, but imo they're not as durable as the 501's. I owned a pair of Levi's that lasted all of highschool and probably half a decade after.

I think when I graduate and start working, I'll get 501's and get them tailored, that'll be ideal.

Although I can't remember the specific model, American Eagle and Wrangler sell pretty good durable jeans as well.

I've done physical labor in all of these and gave them wear and tear; anything the stretches looks very nice but isn't the most durable.

I could be wrong because this is very anecdotal, but this is my experience
