There are a few different kinds here but mostly Nature Babies and Motherease as I found those to be the most bombproof styles. I find that the 'Birth to Potty' do not work for newborns (unless your newborn 17lbs!) so these work wonders in the meantime (Plus they are less bulky under newborn clothing) All the nappies and wraps work together (except the Bitti D'lish).
