These Mommy Mouse inserts have an innovative shape: they do not have elastic bands but side flaps indicated to hold back the liquid poop spills typical of infants. Thanks to their particular shape, they gently wrap around your little one's legs: they don't squeeze or leave marks, but they are extremely effective against leaks (NO – Crush system). These inserts are available in different materials, each suitable for a different need: All cotton insert with silky cotton layer: made of 100% certified organic cotton which is extremely delicate and natural in contact with the skin. Does not dry out and leaves a wet feeling. To guarantee the right comfort for your little one, it must be changed often. NB: it is more absorbent than microfiber inserts. Microfiber insert with silky cotton layer (made of 100% natural organic cotton that is very soft on the touch): your baby's delicate skin will be in contact with a delicate material, free of any chemical substance. NB: less absorbent than the all cotton insert. Microfiber insert with thermo air layer: this innovative material provides excellent thermal insulation. It is therefore a perfect insert for the summer: it will leave your baby's skin fresh and dry. NB: less absorbent than the all cotton insert. Microfiber insert with microfleece layer: thanks to this insert, your baby's skin will stay dry for longer because the microfiber part will retain the wet, guaranteeing a real feeling of comfort. NB: less absorbent than the all-cotton insert. These inserts are a NEW BORN size: great for newborns from 2.5 to 7 kg. Dimensions: 17 x 15 x 3 cm This product has won the HIT FAIR KIDS PRODUCT AWARD.
