The Benefits of Supima Cotton

Supima is a name you will see on cotton t-shirts, sheets and knitwear. This guide explains what it means, how it compares with other cottons, and how to look after it.

Key points

• Supima is a trademarked name for American-grown Pima cotton, with extra-long staple (ELS) fibres.
• Longer fibres can be spun into smoother, stronger yarn, which is why ELS cottons are usually described as soft and hard-wearing.
• Garments sold as Supima are licensed through the Supima association, so look for the name on the label.
• We use Supima cotton in selected pieces, alongside other cottons, TENCEL™ Modal and TENCEL™ Lyocell.

What is Supima cotton?

Supima is a trademark owned by the Supima association, a non-profit body representing American Pima cotton growers. Pima cotton is a type of extra-long staple cotton, and Supima is the American-grown version sold under that brand. Brands that want to label products as Supima need to be licensed to do so.

What makes it different?

Cotton fibres are measured by length (staple). Most cotton in the world is medium staple. Extra-long staple cotton makes up only a small share of production. Longer fibres mean fewer fibre ends poking out of the yarn, which generally gives a smoother surface and a yarn that is less prone to pilling and wear.

Comparing cotton varieties

Supima and Pima

All Supima is Pima, but not all Pima is Supima. Pima is also grown in other countries, such as Peru, and sold under different names. Supima refers specifically to the American-grown cotton covered by the trademark.

Supima and Egyptian cotton

Both are long-staple cottons with a good reputation for softness. The main differences are where they are grown and how the names are controlled. Egyptian cotton is grown in Egypt; because the name has been widely used on products of varying quality, it is worth checking the fibre content and the brand rather than relying on the name alone.

Supima and Sea Island cotton

Sea Island cotton is an extremely long-staple cotton historically grown in the West Indies. It is rare and expensive, so it is usually found only in very high-end products.

Supima and organic cotton

These are different things. Supima describes the type and origin of the cotton. Organic certification describes how cotton is farmed (for example, restrictions on synthetic pesticides and fertilisers). Cotton can be one, both or neither, so check the label for the specific certification you are after. We do not describe our cotton as organic.

Supima and standard cotton

Standard cotton has shorter fibres and can still make very good clothes. Supima tends to cost more to buy, and what you are paying for is the longer fibre and the finer yarn it allows.

Advantages in clothing

• Softness: a smooth yarn gives a smooth hand-feel, which is why Supima is popular for t-shirts, vests and basics worn next to the skin.
• Durability: stronger yarns tend to resist pilling and thinning, although construction and care matter as much as fibre.
• Colour: well-spun cotton takes dye evenly, and with careful washing colours can stay clear for longer.
• Breathability: like all cotton, it is a breathable fibre for everyday wear.

Supima at Lavender Hill

Styling Supima basics

Fine cotton basics are the foundation of most outfits. Wear a Supima tee on its own with jeans, under a blazer for work, or as a base layer beneath knitwear. Neutral colours give you the most combinations.

Care tips

• Wash at the temperature on the care label, on a gentle cycle for lighter colours and finer knits.
• Use a mild detergent and avoid bleach.
• Wash inside out to protect the surface of the fabric.
• Air dry where possible, or tumble dry on low if the label allows. Cotton can shrink with high heat.
• Iron on a medium heat, if needed, while the fabric is slightly damp.

Frequently asked questions

How does Supima compare with Egyptian cotton?

Both are long-staple cottons known for softness. Supima is grown in the United States and sold under a licensed trademark; Egyptian cotton is grown in Egypt. Check the fibre content and the brand, not just the name.

Is Supima organic?

Not necessarily. Supima is about the variety and where it is grown. Organic is a separate certification, so look for it specifically on the label if it matters to you.

How can I check a product is genuine Supima?

Look for the Supima name or logo on the label, and buy from brands that state the fabric clearly. If a label only says "premium cotton", it does not tell you the variety.
