believe it or not it doesn't, fleeecy material actually keps baby very dry as it wicks away lots of moisture

http://www.thenappylady.co.uk/ Is a really good site to have a look at

If you're good with a sewing machine, you can always make your own :P I don't even have a baby yet, and I'm already planning on making my own,...I'm just going to use the gerber cloth diapers in the middle, add a fleece liner(to keep moisture away) and a cute fabric on the outside, along with some kind of closure of course(probably velcro).
