5-15kg OS

OS pocket diapers are the most universal reusable diapering system, designed to grow with your baby. They typically fit from around 5 to 15 kg, thanks to adjustable snaps and a flexible cut that sits well on both smaller infants and active toddlers. The inner pocket allows you to choose the absorbency level – from light daytime inserts to thicker combinations for naps and longer outings.

 

Pupus OS pocket diapers are sewn in Poland from certified, breathable fabrics that are gentle on the skin while providing excellent leak protection. The soft inner layer wicks moisture away quickly, and the outer PUL is elastic, durable, and waterproof. This makes OS pockets a great choice for parents who value flexibility, comfort, and the ability to customize absorbency as needed.

 

These diapers perform well in everyday use, in daycare, on walks, and even at night with the right inserts. OS pocket diapers are an economical, long-lasting option for children who can use the same size for many months.
