4 x 8 x 4 Size

• Prefolds come in different sizes which relate to the level of absorbency you require. Unlike most other cloth and disposable diapers, a prefold diaper varies in thickness across the diaper so there is a measurement for both the sides and the middle of the diaper. The most popular prefold size is 4 x 8 x 4 which means 4 layers on each side and 8 layers in the middle, according to Prefold Cloth Diapers company website. This size structure provides a good balance of high absorbency and slim-fit, therefore reducing the risk of leakages but without too much bulkiness.
  
  

Unbleached Color

• Unbleached prefold diapers are superior to the bleached alternative, says Diaper Pin. This is because they last longer as the fibers haven't been weakened by the bleaching process. Unbleached prefolds are ivory colored instead of bleached white, they contain less pollutants and are softer because bleaching can remove the cloth's natural oils.
  
  

100 Percent Organic Cotton Prefolds

• Cotton is one of the most popular fabrics used to make prefold diapers particularly those made with 100 percent organic cotton, says Baby Kind Real Nappy Adviser Emily Crocker. This is because they contain no harsh chemicals which could irritate the skin and be harmful to the environment, they are longer-lasting and are extremely soft to the touch. Organic 100 percent cotton prefolds are more expensive than standard cotton alternatives, however the benefits usually outweigh the higher cost for consumers, according to Diaper Pin.
  
  

Hemp Prefolds

• Prefolds made out of hemp are fast becoming a competitive alternative to cotton because of their superior durability and absorbency capabilities, according to Diaper Pin. Made from the plants of Cannibis Genus, hemp prefolds have a good resistance to mold and are soft and comfortable to wear, says Prefold Diapers.
  
  

Chinese Prefolds (CPF)

• Prefolds made in China, also known as CPFs are widely regarded as extremely economical, well-made and durable, says Crocker. These prefolds are made from cotton twill which is characterized by its diagonal weave. This means that the diaper is very durable and stain-resistant because the use of multiple threads makes it harder for stains to stick to the fabric.
