These new Petit Lulù inserts consist of a base (composed of 60% bamboo viscose and 40% organic cotton) and a longer insert that can be easily added thanks to a snap, to ensure maximum absorbency. This insert is made on the outside of 60% bamboo viscose and 40% organic cotton, while the inside is 80% cotton and 20% polyester. All you need to do with this comfortable model is a classic Petit Lulu cover (not included) to get an ALL – IN – TWO diaper. The size is suitable for children from 4 to 15 kg and, thanks to its high absorbency, it can also be used at night. The small and soft elasticated wings around the baby's legs protect the outside from any pee spills. It can be machine washed and dries easily as the inner insert can be detached and laid out separately.
