I buy cheap blue jeans, usually from Amazon or Walmart. Wrangler has a sub-brand called Rustler that was on sale recently. Turns out they fit me really well, so bought a bunch. I doubt they’ll last more than a couple of years, but I also have a bad habit of “accidentally” working on cars without changing into my work clothes. So my jeans are usually ruined by dirt & grease stains long before they actually wear out.
