Snap in one (SIO)

Diaper SIO (Snap-In-One)

The SIO diaper consists of a cover and an absorbent layer, its parts are connected with press studs, which prevents the inserts from moving.
When changing the diaper, only the inserts can be replaced and the cover can be used again.
Thanks to the connection of the cover with the inserts with nappies, diapers are easier to wash and dry faster than AIO.
Often such a diaper allows you to attach one or two inserts, which allows you to adjust its absorbency.
