“Bio-terry” SIO insert in M size consists 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.

This SIO insert in M size will be a great solution as a single insert to use as a set with One Size wool cover. What is important that the snaps are placed only on a bottom side of an insert so the baby has a smooth side beside his bum. You attach the insert to the cover with two snaps, one on each end of the insert. This allows you to snap the insert easily and quick. When it gets dirty, you simply un-snap them with a single move of your hand and throw the insert to your dirty nappy bucket.

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.

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.

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)
