Hi everyone - Is there such a thing as a nylon diaper cover that is not a pull-up? Preferably a one-size snap up and snap closed, though I'd take velcro too. I have some Dappi pants and absolutely love the material they are made from - so soft and trim and completely leak-proof (even after 18 moths of moderate use as back-ups plus hot water washes and going in the dryer). I far prefer it to PUL which is so thick and feels icky to me. Obviously there's a problem with nylon, what am I missing?
