I got a sample of Abena L4s with the last pack of Bambinos that I ordered. I was very disappointed. Both of the diapers leaked almost immediately. They have a ton of padding, but they didn't seem to have any kind of elastic to keep the urine in while that padding did its job. I'm wondering if I just am bad at getting a snug fit or if should have bought the M4; I'm not in the size range of any large diapers, it's just my way of making sure that they rise up past my belly button.
The annoying part of that is that, though, is that every other brand of diaper fits just fine in a large and I never have leaking issues unless it's like a Depend or something.
