Kids' clothing materials

Updated 08.06.2026 · about 7 min read

The material decides whether a garment breathes, itches, lasts and holds its shape after washing. Once you know when to pick cotton, when merino wool and when a technical fabric, you make fewer wrong buys and the child stays comfortable both at school and outdoors.

Materials worth knowing

Natural fibres

Cotton is the everyday workhorse: soft, breathable and easy to wash, ideal for tees, underwear and anything next to the skin at home. Merino wool warms even when thin, wicks moisture away from the skin and resists odour, so it works well as an outdoor layer and for travel.

Synthetics & technical fabrics

Fleece is a light, warm mid-layer that dries fast — perfect under a jacket. Polyester is hard-wearing, does not crease and suits sportswear and waterproof outerwear. The downside: pure polyester breathes less and can feel clammy against sweaty skin, so keep it as an outer layer.

Blends & elastane

A cotton blend with a little elastane (around 3–5%) holds its shape, recovers after washing and sits better at the knees and cuffs. A touch of elastane in leggings and trousers gives freedom to move without bagging out. A high synthetic share, though, makes the fabric less breathable.

How to read a fabric composition with confidence

  • Composition is always shown in percentages and in order of size — the first fibre dominates, so 95% cotton 5% elastane is essentially a cotton garment.
  • Next to skin, favour soft, breathable naturals: cotton, merino wool or a blend wick moisture and reduce irritation.
  • Avoid 100% polyester directly against the skin for everyday wear — it breathes less and traps moisture; a technical fabric belongs in the outer layer.
  • Look for OEKO-TEX® or another certificate: it confirms the fabric has been tested for harmful chemicals and is safe against a child's skin.

Quick tips for choosing material

The base layer next to skin should be cotton or merino, not pure polyester.
For winter, choose in layers: merino or cotton on the skin, fleece in the middle, technical fabric on top.
Always check the lining and hood-edge material too — that is where irritation often comes from.
A small elastane percentage is a plus; a large synthetic share in an everyday tee is more of a minus.

Frequently asked questions

Which material is best for sensitive skin?

Soft cotton and fine merino wool are the kindest to sensitive skin: they breathe, wick moisture and rarely irritate. Look for flat seams and tag-free pieces, and favour OEKO-TEX® certified fabrics that have been tested for harmful substances.

Is merino wool itchy on kids?

Ordinary sheep wool can itch, but merino fibre is much finer and thinner, so most children tolerate it well directly against the skin. If a child is especially sensitive, choose a thinner merino top or wear a cotton base layer underneath it.

Why do some clothes make kids sweat?

Usually the cause is a high synthetic share — pure polyester next to the skin breathes little and does not move moisture out, so sweat stays close to the body. Swap the base layer for cotton or merino, and keep technical fabric for the outer layer instead.

What percentage of elastane is good?

For everyday clothes, around 3–5% elastane is plenty: it gives freedom to move, holds shape and improves fit at the knees and cuffs. A higher share makes the fabric stretchier but less breathable, so natural fibres should still dominate.
