What combed yarn means for a t-shirt
Short answer: Combing is an extra step where the shortest fibres are sorted out before the yarn is spun. The result is a smoother yarn that pills less and feels softer.
What combing does
The short fibres are the ones that work their way out of the fabric and turn into pilling. If they are removed beforehand, it happens less often.
Smoother surface
A combed yarn has fewer fibre ends sticking out. That gives a smoother surface and a more even fabric.
That is why it costs more
Combing removes part of the raw material and takes time. That shows in the price.
Where it matters most
In t-shirts and underwear worn directly against the skin, the difference is felt most clearly. See bamboo t-shirts for men.
Not always stated
Like the spinning method, it is rarely stated on the label. It shows in the fabric after six months of use.
Together with fabric weight
Combed yarn in a light quality can last better than uncombed in a heavy one. Both matter.

For women
The same difference applies on the women side, where thin basic pieces wear fastest. See bamboo tops for women.
Frequently asked questions
What is the difference between combed and uncombed yarn?
Combed yarn has had the shortest fibres sorted out and is therefore smoother.
Does combed yarn pill less?
Yes, because there are fewer loose fibre ends.
Is it stated on the label?
Rarely. It shows in how the fabric looks after a few months of use.
