> But then why Nike/Adidas/Quicksilver/etc cannot bring back clothes from the 90s?

They can, but people wouldn't want to pay the price. When adjusting for inflation, clothes today are much cheaper than 30 years ago, and the main producers of high-quality cotton (Kazakhstan and Egypt) are having continuous drought problems so the best raw material is even more expensive.

The combination of customer expectation for low prices, and more expensive raw materials, exacerbated by lower production volume, means that very few would be willing to buy. As an example, take a look at the high quality jeans market: there are a few niche companies in Japan, Europe, US and Canada producing jeans at the same level of quality as 50-100 years ago, in some cases the exact same model as, say, a 1950's Levi's. Those jeans start at $200 per pair, but go even up to $400-500 and the manufacturers are barely surviving.

I feel for them because I wouldn't mind paying 2/3 times the price for something of measurably higher quality and durability, but it takes effort and dedication to accomplish that as a customer. Effectively the market is saturated with premium-branded items that are marginally better or sometimes worse (a lot of what you see as "technical clothing" comes across that way at least), you feel gaslit by marketing, fake reviews and astroturfing campaigns, and there are only so many deceptions, defeats and financial losses you can sustain before going back to the devil you know: the default everyone else is buying.
