If you've had a look at our product pages, you'll have noticed that our bottoms — the trackies, leggings, and pull-overs — carry the OEKO-TEX Standard 100 certification. It's a name that sounds official and important, but what does it actually mean in practice?

The short version

OEKO-TEX Standard 100 means the finished fabric has been independently tested for over 100 harmful substances — things like heavy metals, formaldehyde, pesticide residues, and certain dyes that have been linked to health issues. If anything nasty turns up above safe thresholds, the certification isn't granted.

Why it matters for kids specifically

Children's skin is more permeable than adult skin, which means they absorb more of what they come into contact with. Kids also put things in their mouths, rub their faces on their clothes, and spend a lot of time on the floor. The standard at which a fabric is tested varies depending on who it's intended for — and products for babies and toddlers are held to the strictest threshold of all.

What it doesn't cover

OEKO-TEX Standard 100 is a product certification, not a supply chain one. It tells you about what's in the fabric, but not about the conditions under which it was made. That's where our GOTS-certified tees take a different approach — covering the whole journey from farm to finished garment.

Together, these two certifications cover a lot of ground. We chose them deliberately because we wanted to be able to say — with receipts — that we take what goes on your child's body seriously.
