Collection: 04 - One size diapers (One Size = OS) - approx. 6-15 kg, approx. Dress size 62-92/98

Diapers of different sizes also exist in cloth diapers, the largest group of which is the so-called one-size-fits-all, or AIO diapers. It's English name is onesize, which is why we often see the abbreviation OS. The name is a bit misleading, because the one-size-fits-all diapers are actually only cover M and L sizes, or approx. sizes from 62 to 92/98, but there are manufacturers whose covers also reach XL sizing. OS diapers are usually recommended for 6-15 kg, but this may vary slightly from manufacturer to manufacturer. For these sizes, the shape of the baby and the thickness of the absorbent parts always determines how long the diaper will fit.
