I bought these cloth diapers because I wanted to give cloth diapers a try. Before my son was born, I saw these on sale for 40% off (cost me about $30 for 5). You need to buy these in three sizes for the duration of a child's diaper days - infant, medium & large. They are supposed to have the inner waterproof shell, however because it is cloth all around, the liquid wicks around the edges towards the outside, which then wicks into the clothes. I found these did not work at all! On the positive side, their customer service was pretty good. After calling them and telling them how disappointed I was in their product, they sent me 4 shells for free to wear over the diaper. These shells did help, however they are a very bulky diaper unlike the newer style of pocket diapers.
