Dude i got 2 pair of jeans like 4 years back for 2k from a very local shop, wore them for like 4 years yes 4 years gathering, field work, etc etc they were robust
got another 2 pairs like 6 months back for 1800 but they don`t seem that good of a quality but still does the work for a student. look around you might find good things in very less price.
