Size XL PUL covers are a proposal for older babies and toddlers. They fit children over 9 kilos of weight up to around 20kg.
However, you should remember that the weight range is approximate and how long the diaper will fit depends primarily on the child's body measurments, and those, as we know, are very different.
XL Magabi covers are designed mainly for use with flats, prefolds and fitteds. They have been designed to cover the biggest night-time fitteds, yet nevertheless look neat.
XL Magabi can also be used with inserts, so they have a front tab to support the it.
However, it should be kept in mind that the inserts adheres well to the body - the diaper must be sufficiently tense in length. Therefore, we do not recommend using them with inserts when children are in a lower weight limit (about 9-10 kg).
