Yeah it's pretty amazing if you are buying a reputable brand with consistent sizing in a size you know works for you. Also don't be afraid to bid - a lot of time people will list something for $60 and take $20

I wear things unusually hard but I’ve consistently worn through Kuhl products in ~3 years or so

Alberto makes amazing jeans that fit like high-fashion jeans and last forever. Look for the T400 fabric. Made in Germany since 1922 or something, I've had them and worn them every day for years and they look the same. They're $200+ but after I got the fit right get them on Poshmark for $20-40. At that price there's no comparison
