The 10 brands with the most natural fibre.

Look at the names. There's a clear split.

You've got the brands that built their whole identity around natural fibre — Pangaia literally has the periodic table on their tags. Everlane wrote essays about it. Those ones make sense; they had to score well or the entire brand falls over.

But then there's the other group. Levi's. Barbour. Some of the more established heritage names on the list. None of these brands have ever called themselves sustainable.

Barbour wax jackets are designed for standing in Scottish rain holding a fishing rod. Levi's invented the modern jean for actual gold miners. These brands are mostly cotton and wool because cotton and wool are what survived being worked in. Polyester pills. Acrylic melts near a welder. Natural fibre just held up — so they kept using it. They never pivoted. They just kept doing the thing.

A clean catalog isn't an accident, and it isn't always about charging more. Levi's isn't expensive. They got to the top of this list by making clothes for people who couldn't afford to replace them every six months. That's it. That's the trick.

So when the headline tells you fashion is broken — sure, a lot of it is. But the receipts also say there are ten brands you can walk into right now where the odds of buying something real are stacked in your favour. Some are luxury, some are loungewear, some are literally for digging trenches. Worth knowing the names. Worth saying them out loud.

If you want to see what the opposite end of this looks like, we found that polyester turned up in 55 out of the 57 brands we scraped — including most of the brands in this top 10. The two are not mutually exclusive.

And if you want a walkthrough of what natural fibre looks like inside a brand that didn't make this list, here's where the natural pieces hide inside Zara's 13,685-product catalog.
