Where to buy actually great quality jeans?

Hello 👋🏼. So I need to buy 2 or 3 good pair of jeans. I want to buy actually good quality, no Levi’s stuff. I don’t want any plastic fiber in them, I don’t mind thick, sturdy rough jeans. I just want them to last, age decently, and to have a good value for the money I spend. None of the thin stretchy stuff. Also, don’t care super much about fit, but I am usually more on the skinny side. Do you know any brands, manufacturers, stores that sell this kind of pants? I also don’t mind importing. And I don’t mind spending money, as long as it is for quality and not brand or “fashion”.

Thank you in advance for your help. I’ve been a long time lurker.
