It is, technically speaking, the most important part of any EasyFree 3in1 nappy. The pouch is there to keep the liquids inside the nappy and that no humidity gets out. When changing, pay attention that the pouch fully develops and no material protrudes. The elastic must be in contact with the skin. With your finger, control that the pouch is well in place.
The EasyFree Pouch is made of 100 % polyester with polyurethane coating.
