I'd love to find an economic, medium-capacity blastic-backed nappy that punches above it's weight. In the UK we had ID Expert Slip Super PE backed... came in bags of 28, wicked well. But here in NZ we have the choice of rearz/incontrols that are expensive and overkill (IMHO), and for all their ISO capacity, I find they leak early, holding no more than much thinner nappies I've used in the past. I really think there is a gap in the market for something that will hold 1500-2000ml safely without being huge.
