1. Thanks to originally designed microporous material "air through", the merries' diaper has a superb level of breathability. 2. The latest innovation: a frame made of special airy mesh designed exactly in a shape of baby’s buttocks guarantees the diaper’s tight contact with a skin, and so provides the child with an absolute freedom of movements. 3. The diaper's inner surface is made of a soft cotton, which carefully protects the baby’s tender skin from any irritation. 4. Extract from "magic hazel" hamamelis wouldn’t let any inflammation or dermatitis rise in the areas where the diaper’s surface touches the baby’s skin. 5. The indicator of inflation will always let the mother know when it’s time to change the baby’s diaper: as the diaper gets filled, the 3 stripes change their color to blue.
