I wore my heavy weight Carhartt carpenter jeans about every other day for a few years until I started using them for house work. I would've thought the knees would have holes by now (5 years in) with the recent crawlspace work I've been doing.
Great taste. I was formally introduced to Carhartt deep in the aisles of an Ace Hardware store by a man who explained how he could fit his firearms in a pair of coveralls.
