Smartwool socks. I replaced mine this year because they were getting holes, the ones I was replacing were purchased in 2014 and I wore them daily, had enough pairs to last a week, washed them weekly, they lasted ten years.
Not a brand but cast iron skillets. Some of mine are over 30, they will last essentially forever. And get a big knife you can sharpen, mine wasn't even a good brand and lasted almost 30 years.
Smartwool enshitified by dropping their warranty to two years. Used to be able to take an old pair to my outfitter and pick out a new set, no questions.
Like the other user said, check out DT. EZPZ replacement.
