1. Re-usable cloth shell
2. Water-proof liner
3. Disposable or Cloth insert
So in theory you should only be changing out the insert. However, I almost always found it easier to change out the liner and insert, if not the entire diaper. So what makes these diapers stand out from the rest you might ask. The fact is that they are the trimmest cloth diapers around. My wife is a photographer and we have used them exclusively in his monthly and holiday photos. Follow her blog to see her newest projects at Little Paper Crane. Also the fact that its possible to reuse the gPants and liners make them a great travel diaper. We can easily fit a days worth of diapers into his diaper bag and have room for everything else a baby or dad might need.
Like I stated earlier, gDiapers are not a perfect diaper. In my opinion no cloth diaper is perfect, but I believe you can have a perfect diaper stash. Mine would never be without gDiapers. Please take a little time to visit gDiapers, as they might have the last piece you need to complete your ideal stash.
