Organic cotton
Organic cotton is the same fiber as regular cotton, farmed differently. What matters is whether the claim is certified, and fraud has been a real problem.
At a glance
Origin: Plant fiber from the cotton boll, grown under organic farming rules.
How processed: Natural: ginned, spun and woven like any cotton. “Organic” describes how the cotton was farmed; textile standards such as GOTS cover processing.12
What it is and how it’s made
In the US, organic cotton is grown under National Organic Program farming rules, but the program has no textile-processing standard; a finished garment can carry the USDA seal only if it is fully NOP-certified.1
Under GOTS, a product labeled “organic” needs at least 95% certified organic fiber, and “made with organic” at least 70%.2
About 706,000 tonnes of cotton, 2.9% of the world crop, was certified organic in 2023/24.3
How it wears
| Feel and quality | “Organic” is a farming and certification claim, not a fabric property; the rules cover how cotton is grown and processed, not how it feels.12 |
|---|---|
| Odor | In a gym-wear study, cotton shirts carried less odor-causing bacteria than polyester after exercise. That finding is about cotton in general.4 |
| Breathability | Exercise studies comparing fabrics found fiber type made little difference to body temperature.56 |
Environmental notes
- Conventional cotton is irrigation- and pesticide-heavy in many growing regions.78
- A life cycle study commissioned by Textile Exchange put organic cotton’s irrigation (blue) water at 182 m³ per tonne of fiber, against 2,120 m³ for a conventional benchmark.9
- Across crops, organic yields average about 25% lower than conventional, so more land can be needed per tonne.10
Counterpoints and caveats
- Fraud: in 2020 GOTS reported evidence of fraudulent organic cotton certificates in India, and a 2022 New York Times investigation raised wider doubts about Indian organic cotton.1112
- The water comparison was commissioned by Textile Exchange and funded by brands including H&M and Nike.9
- Lower yields can offset per-hectare gains.10
Buying tips
- Look for a GOTS label naming the certification body and licence number, not just the word “organic.”2
- “Made with organic” can mean as little as 70% organic fiber under GOTS.2
- Organic cotton blended with polyester or elastane isn’t all natural by FabricTruth’s rule.
Common garments
- Tees
- Oxford and flannel shirts
- Chinos and denim
- Underwear and socks (socks usually blended)
