Puppi's SIO system is an AI2 (all in two) system of cloth diapering where you can snap the insert inside of a cover. Look for the SIO Puppi covers which include snaps inside for the inserts.

Sold individually

This SIO insert in M or L 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. Size M consists of 4 layers of a very absorbent and soft cotton. However, due to the stiffening of natural fibers after multiple washings, "Cuddly&Snuggly" inserts are recommended to those who have the possibility of drying them in a tumble dryer to keep them soft.

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.

In all our inserts, our PUPPI logo labels are placed on the bottom of the insert, so they don’t irritate baby’s delicate skin.

The possibility of snapping insert to the wool cover lets you to change the diaper very quickly, so don’t worry that the insert will move or fall out while your baby is moving. This system is very friendly particularly for daddies, grandmas or babysitters in nurseries, as well as all parents who are beginners in cloth diapering- with SIO system you don’t need to think too much about how to use the nappy. Snap inserts into the cover, put diaper on baby and go!

We recommend the following configurations of SIO inserts:

- 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

- for heavy wetters, place an smaller insert under the size M or L. Sterling & Me recommends Geffen hemp inserts.
