SIO insert in size S will be great to use as an booster together with size M insert. It has one double-sided snap allowing to snap it into the cover and the other insert.


“Bio- terry” SIO inserts in S size consist of 4 layers of a unbleached, ecological cotton terry with a tiny loops which makes inserts very soft and delicate for baby’s skin. Loops make “Bio-terry” inserts very absorptive as the surface is increased comparing to other materials.

Our SIO System consists of a wool cover and absorbent inserts which can be easily snapped together. Our snap-in inserts are available in three sizes: S, M and L. Pair the SIO cover with varied combinations of snap-in inserts.

The possibility of snapping inserts with the wool covers lets you change the diaper very quickly, so you don’t need to worry that the insert will move or fall out while your baby is moving. This system is particularly friendly for daddies, grandmas and babysitters as well as for parents that are beginners in cloth diapering as they don’t need to think how to use the diaper. SIO system will be also great for a fast diaper changes for little runners. For babies that run away while you try to change the diaper we recommend the velcro closure. When the insert is snapped with the wool cover, putting the diaper on is exactly same as if you use disposable diaper.

Please note: We offer One Size and One Size Plus SIO wool covers. It is not available in smaller sizes intentionally. The reason is that it doesn’t work before the solid meals are introduced to baby’s diet, as milk poo needs an extra protection not to leak out.

We recommend the following inserts configurations:

- a single size M insert (33 cm long) for everyday use together with OS cover or single size L insert (35 cm long) together with OS or OS+ cover

- insert in size M or L snapped together with size S (29 cm long) for heavy wetters or for walks and naps (used together with OS or OS+ cover)
