Oeko-Tex is the worlds leading experts on testing for harmful substances in textiles. What does this  actually mean?

Purchasing clothing with the Oeko-Tex 100 label assures you that the garment doesn't contain any chemicals or harmful substances. The 100 standard subjects clothing that comes into contact with the sensitive skin of babies and children to the toughest requirements of all. All Oeko-Tex 100 must be dyed so that their colours are resistant to saliva.

Oeko-Tex is an independent institute that sets higher standards concerning chemicals and harmful substances than does the legislation and it is the worlds leading certification of its kind.

The garments are thoroughly examined, all down to the thread, and since they are in such close contact with the skin there are stricter requirements than for other products. The standard also sets stricter requirements for clothing for children up to the age of 3.
