I've been looking around for an adult-sized diaper wrap, which performs the same function as plastic pants but fastens in the front with Velcro like a disposable. Something similar to this: Super Whisper Wrap Diaper Cover - By Bummis would be awesome. The 'fabric' is laminated, I believe with PUL, which is waterproof and extremely durable (and allows for a wider array of cute prints); it's also gusseted (standing leak guards) which is unique.
I've been looking around internet shops as well as Ebay and have found many similar baby-sized products, but nothing yet for adults. Anyone else come across something?
