Thirsties is revolutionizing the most widely used cloth diaper in the world. Prefold cloth diapers are popular for their affordability and are the most common diaper supplied by cloth diaper services. Though they don't share all the bells and whistles as other more modern cloth diapers, they have their definite and permanent place in the industry and they have been proven dependable and economical. However, Thirsties Duo Hemp Prefolds are no ordinary prefold! We've solved many of the cons of prefold diapers in our patent-pending design. Ordinary prefolds are bulky and take a long time to dry. When hung to dry, they can become stiff and crunchy. In addition, most prefolds are 8 layers thick in the middle, which makes it difficult to clean all layers of the diaper thoroughly.
