Pima cotton
An extra-long-staple (ELS) cotton from Gossypium barbadense, grown mainly in the southwestern US and Peru. Longer fibres make a smoother, stronger, less pilling yarn.
How it’s made
- 1Grown from G. barbadense varieties, historically developed in Arizona with help from the Pima people (hence the name).
- 2Long fibres are combed to remove short ones, then usually ring-spun into fine, smooth yarn.
- 3Knitted into jersey or woven into shirting.
What to look for
- 'Pima' isn't a protected term outside the US Supima licence, so blends may be sold as Pima.
- Peruvian Pima is a separate origin and often good quality.
- Combed and ring-spun yarns on the label.
