Chinese Prefold Diapers

What are Chinese Prefold Diapers?  
Rectangular shaped flat cloth diaper with an absorbent
pad already sewn in.  Come in a variety of sizes and
thicknesses.
The prefold is thicker in the center for better absorption
and thinner at the sides for more comfort. To use a prefold
cloth diaper set you'll need three pieces. The cloth, the
pins or Snappies, and a vinyl cover. The vinyl cover is
needed to protect your baby’s clothing from getting wet.

Here are the sizes that Chinese prefold diapers come in.
