T-Shirt Materials and Fibres
Fabric quality is what you are really paying for in a premium tee. This hub explains the cotton grades, natural alternatives and synthetic blends you will find on our labels, and what each one does for softness, durability and shape retention.
Cotton grades
Cotton
The default tee fibre -- breathable, soft and easy to care for, with quality varying enormously by grade.
Why it dominates
Cotton is comfortable against the skin, absorbs moisture and washes well. Nearly every classic tee starts here.
The catch
Not all cotton is equal. Staple length (the length of each fibre) is the key variable behind softness and durability -- see the premium grades below.
Pima Cotton
A long-staple cotton prized for exceptional softness, strength and resistance to pilling.
What makes it special
The longer fibres spin into a finer, smoother yarn that stays soft wash after wash. Read more in the pima cotton glossary entry (/pages/glossary-pima-cotton).
Where you meet it
Pima and its trademarked form, Supima, appear in premium tees where a luxurious handle is the point.
Supima Cotton
A trademarked, certified grade of American Pima cotton guaranteeing genuine long-staple quality.
What it guarantees
The Supima label certifies the cotton is 100% American Pima, traceable and long-staple -- a mark of authenticity, not just marketing.
Feel and wear
Expect a soft, slightly lustrous surface and strong colour retention. It sits at the top of everyday tee fabrics.
Egyptian Cotton
A famous long-staple cotton grown in the Nile region, known for a smooth, fine and durable yarn.
What makes it special
Like Pima, its long fibres produce a soft, strong yarn. See the Egyptian cotton glossary entry (/pages/glossary-egyptian-cotton) for detail.
Buyer's note
The name is widely used, so genuine long-staple Egyptian cotton is best trusted from established brands.
Mercerised Cotton
Cotton treated to give a subtle sheen, stronger colour and a smoother, more polished surface.
How it works
The mercerising process swells and straightens the fibres, adding lustre and dye uptake. More in the mercerised cotton glossary entry (/pages/glossary-mercerised-cotton).
Where you meet it
Mercerised cotton is common in smarter polo shirts and refined tees where a crisp, slightly glossy finish is wanted.
Natural fibres
Organic Cotton
Cotton grown without synthetic pesticides or fertilisers, better for soil, water and the people farming it.
Why it matters
Organic farming reduces chemical load and often uses less water. See the organic cotton glossary entry (/pages/glossary-organic-cotton).
On the label
Look for a recognised certification rather than the word alone -- it is covered further in the sustainability hub (/pages/tshirt-sustainability).
Linen
A crisp, breathable plant fibre that excels in heat, softening beautifully with age.
Why choose it
Linen wicks moisture and dries fast, making it superb for summer. Its natural texture and creasing are part of the appeal.
Care
Linen relaxes and softens over time. Embrace the creases or press lightly -- it is a warm-weather luxury, not a wrinkle-free option.
Modal and Lyocell (TENCEL)
Silky, sustainable fibres made from wood pulp, adding drape and a cool, smooth handle to tees.
What they do
Modal and Lyocell (branded TENCEL) are soft, breathable and drape more fluidly than cotton, often blended in for a luxurious feel.
Eco angle
Lyocell is produced in a closed-loop process that recycles its solvents, making it one of the more responsible man-made fibres.
Synthetics and blends
Polyester and Recycled Polyester
A durable synthetic that adds strength, shape retention and quick-drying performance, increasingly from recycled sources.
What it adds
Blended with cotton, polyester improves durability and reduces shrinkage; on its own it powers performance tees. Recycled polyester cuts the footprint.
Trade-off
Pure polyester breathes less and can hold odour, which is why anti-odour finishes appear on performance tees -- covered in the performance hub (/pages/tshirt-performance).
Elastane (Stretch Blend)
A small percentage of stretch fibre added to cotton for a closer fit and better recovery.
What it adds
Just 3-5% elastane lets a tee move with the body and spring back rather than bagging at the elbows and hem.
Where you meet it
Stretch blends suit slim and muscle-fit tees where a clean, close line needs to survive movement.
Frequently asked questions
What is the best cotton for a t-shirt?
Long-staple grades like Pima, Supima and Egyptian cotton give the softest, strongest and least pill-prone tees. Combed, ring-spun cotton is the quality baseline.
Is a cotton-polyester blend worse than pure cotton?
Not necessarily -- a blend trades some breathability for extra durability, shape retention and quick drying. Pure cotton feels more natural; blends last hard wear better.
What does elastane do in a t-shirt?
A small amount (3-5%) adds stretch and recovery so a fitted tee moves with you and springs back instead of bagging.
