The inserts are specifically designed for the whole SIO / SYSTEM. They have an hourglass shape, with a large area of absorption in both the front and back of the insert (special needs of boys are taken into account).

The inserts have different absorbency levels, chosen depending on the development and changing needs of the child. The SIO diaper is designed in such a way that it can attach different inserts as well as additional SIO Boosters onto the diaper.

You can attach the booster to the hourglass insert or add additional inserts to the POCKET or SHELL diaper to achieve a higher absorption level

Hourglass shape additionally increases its absorbent surface resulting to a higher absorbance capability. The inserts are versatile and can be used in different ways to achieve extreme absorption. The freedom of use depends on your imagination and needs.
