Supima vs Pima Cotton: The Trademark Is the Point
Pima is extra-long-staple barbadense. Supima is that fibre grown in the US by licensed farms. Same idea; one word is policed.

Same species, different paperwork
Extra-long staple means fibres often 1.4 inches and up, which spin into smoother, stronger yarn. Upland (G. hirsutum) is shorter and cheaper. Pima is the ELS barbadense traditionally associated with the American Southwest. Supima (from “superior Pima”) is the grower organization’s mark. If a shirt says Supima, there is a license behind it. If it says Pima, ask who spun it.
Where the premium shows up
Sheets: 300–400 single-ply percale or 300–500 sateen, $90–$200 queen. Tees: 180–200 GSM jersey that does not pill into grey. Socks and underwear: longer life at $14–$22 a pair versus $6 upland.
| Word on the label | What it should mean | Risk |
|---|---|---|
| Supima | US ELS, licensed | Low if the mark is real |
| Pima | ELS barbadense, various countries | Blends, vague mills |
| Egyptian / Giza | ELS if named Giza | Country used as perfume |
| 100% cotton | Legal minimum | Usually upland |
Do not pay ELS prices for a ply trick
Supima 800-count sateen at $49 is still a construction problem. Fibre length cannot rescue four-ply short ends counted as threads, and a licensed name on a dishonest weave is still a dishonest weave. Buy the staple, the GSM or a modest TC, and a mill that will still exist in five years.
Questions, answered
- Is Supima always better than Pima?
- Supima is a guarantee of US Pima source. Peruvian Pima from a good mill can feel the same. The trademark is the audit trail.
- Supima or Giza?
- Both are ELS. Pick the mill and the weave. Do not pick the flag.
- Does Supima shrink less?
- A little, if the cloth is properly finished. Pre-shrunk jersey still wants a cold wash. Staple length is not a shrink spell.
