Bear & Moo Swim Nappies have adjustable domes so one size fits most (OSFM), from 3.5kg to 16kg.
Swim nappies are essentially a PUL nappy shell with a nylon inner, designed to catch number two’s.
They do not have any inserts or any absorbency and do not absorb urine as if they did, they would also be able to absorb water when swimming and the nappy would get too heavy and weigh bub down.
The Bear & Moo Swim Nappies generally fit from approximately 3.5kg to 16kg. The age these will fit depends on your child. They are a slightly smaller fit than the OSFM nappies and do up with the domes to the side / back rather than the front.
They are fully adjustable as all the domes mean that you can size them to fit your bub.
