Product Description


Our inner diaper made of polyester is the core of the WindelManufaktur diaper. It protects the outer diaper, the DropflapDiaper and of course clothes from getting wet. Its special shape allows for a particularly small diaper area that gets wet at all. In addition, the inner diaper is infinitely adjustable for a perfect fit on the little legs. 

Material properties

PUL stands for polyurethane laminate and refers to a water-repellent and breathable membrane that is bonded to a fabric such as polyester. Our PUL is particularly soft and gentle on the skin. The membrane is super-thin, yet robust, and does not rustle.


There are two inner diaper sizes for an optimal fit in the outer diaper or the DropflapDiaper. Please ensure that you choose the correct inner diaper.

  • The 2 to 5 kg inner diaper fits the newborn size outer diaper.
  • The 4 to 19 kg inner diaper fits the size 1, 1.5 and 2 outer diapers.


75% polyester, 25% polyurethane

Care instructions

  • We recommend using a normal colour or heavy-duty detergent.
  • You can wash inner diapers together with your coloured cottons at 40 °C if they are not too dirty. Otherwise, they can be washed at 60 °C together with the diaper inserts.
  • Please use a washing net to protect the PUL membrane.
  • spin at a low spin speed (800-1,000 rpm)
  • do not use fabric softener
