Quick answer: Carded cotton is cleaned and aligned once, so it keeps more short fibres. Combed cotton goes through an extra step that removes short fibres, making the yarn smoother and stronger. Ring-spun describes how the yarn is twisted, producing a finer, softer yarn. Combed ring-spun is the premium combination for hoodies and tees.
Why does cotton quality vary so much?
Cotton starts life as fluffy fibres of all different lengths. Longer fibres make smoother, stronger yarn with fewer loose ends. Short fibres make fuzz, pilling and that slightly scratchy feel. Most of the difference between a tee that feels amazing and one that feels like a bin bag comes down to two decisions: how thoroughly the fibres are cleaned and sorted, and how they're spun into yarn.
What's the difference between carded and combed cotton?
Carding brushes raw cotton to untangle the fibres and line them up. It does the job, but plenty of short fibres and small impurities stay in the mix.
Combing adds an extra step. Fine combs pull out the short fibres and leftover bits, leaving mostly long, parallel fibres. A decent share of the raw cotton gets removed along the way, which is part of why combed cotton costs more. The payoff is a smoother surface, better strength and less pilling.
What is ring-spun cotton?
Ring-spun is about the spinning, not the cleaning. Ring spinning continuously twists and thins the fibres into a fine, tight yarn. The faster, cheaper alternative is open-end (or rotor) spinning, which makes a coarser, hairier yarn you'll often find in budget basics and promo tees. Ring-spun yarn feels softer, looks more even and holds up better over time.
| Term | What it means | How it feels | Where you'll find it |
|---|---|---|---|
| Carded | Cleaned and aligned. Shorter fibres remain. | Can feel rougher and fuzzier | Budget basics |
| Combed | Extra step removes short fibres | Smoother and softer | Mid to premium |
| Open-end | Fast, cheap rotor spinning | Coarser, sometimes stiff | Promo and budget tees |
| Ring-spun | Fibres twisted and thinned continuously | Soft, strong, even | Quality basics |
| Combed ring-spun | Both of the above | Smooth and soft | Premium tees and hoodies |
| Siro-spun | Two strands spun together in one step | Smooth, low fuzz | Premium fabrics |
What is Siro (Sirospun) cotton?
Siro spinning feeds two strands of fibre into the spinning process side by side and twists them together in a single step. The yarn behaves a lot like a two-ply yarn: a smoother surface, less stray fuzz and good strength. Less hairiness means fewer loose fibre ends, and fewer loose ends means fewer pills.
Nerd corner: Sirospun is an Australian invention. Researchers at CSIRO developed it in the 1970s, originally for the wool industry, and the same idea later spread to other fibres, including cotton. The tech behind a smooth premium tee has Aussie roots.
How can you tell what cotton a hoodie uses?
Start with the product description. Look for the words "combed", "ring-spun", or both. If it only says "100 per cent cotton", that tells you the fibre, not the quality of the yarn. In person, better yarn feels smoother and cooler, with less surface fuzz. After a few washes the difference gets obvious: fewer pills and a fabric that still looks sharp.
Does it really matter?
You feel it on day one, because it's softer. You see it at month six, because it pills less and keeps its shape. It's one of those details that stays invisible on the rack and becomes very visible after a year of wear.
FAQs
Is combed cotton better than regular cotton?
Generally, yes. Combing removes short fibres, so the yarn is smoother, stronger and less likely to pill than standard carded cotton.
Is ring-spun cotton good for hoodies?
Yes. Ring-spun yarn is softer and stronger than open-end yarn, which helps a hoodie feel better and last longer.
Is 100% cotton the same as combed cotton?
No. "100% cotton" describes the fibre. "Combed" describes how the fibre was processed. A 100% cotton hoodie can be carded or combed.
Does combed cotton shrink?
It's still cotton, so it can shrink with heat. Whether the fabric has been pre-shrunk matters more than whether it's combed.
Same plant. Very different yarn. Now you know which one you're paying for.
