Very long time diaper wearer and started long ago with pre-folded cloth diapers with plastic pants. And still use them today!
Although a great and fast diaper change, the all in one cloth diapers have their problems. Some of them covered above, but also, they are more a training pant as unless one is adding a cloth booster, they have limited volume. Yes, one can buy them with the upgraded builtin liner, which adds more volume.
My greatest concern with this unique, feature loaded product is the outer shell. That plastic shell has a limited life compared to cloth interior. Good quality cloth diapers have a long life with just basic care. The plastic shell, even the long life products still have a limited life compared to the cloth diaper. When, not if, the shell begins to breakdown, the effectiveness of the all-in-one fails with it. And wearing an outer plastic pant becomes mandatory to keep the world around you dry.
Understanding that with real baby's they outgrow the all-in-one while with adults, that does not happen, as the all-in-one shell fails with time.
Cloth diapers are expensive, but provide decades of use when properly cared for. The AB/DL/IC community has experienced a rapid increase in costs of disposable diapers and everything indicates that those costs will jump again as the cost of crude oil is expected to increase later this year and into next year. Now, cloth diapers will see like increases in cost as international transportation is dependent on the cost of crude oil as well.
Shortages: Any stop in products coming out of China and there will be massive shortage in Adult disposable diapers! Even a limited military engagement in or near the South China Sea and those Bulk Container Ships slow or more likely stops.
