Hey Steve, I have a couple of pair of the Priva AIO in the supply drawer, but only have used them as a cover pant, I never really liked them by themselves and it was one of the first i got for night time problems. Snaps came undone in the middle of the night, leaks at top, back and leg gathers, and not a good fit on me. The second one you listed I have never seen, but they look like a decend AIO unit. Snug at the top and legs is obviously a must. I did buy one of the AIO units from Gabby's, and I like it except for the inner liner, is is only fastened at the front and rear top edges, but did not have any really bad leak problems and lots of room to add a liner or two, although I still used a coverpant. The Kins cloth diapers I use now need the coverpant, they do not have the waterproof outer shell, but if they did, I would lean towards those, I really like them as they are all sewn together inside and just feel like really thick underwear, so much more dignified, just ordered 2 more pair yesterday. I use a BIG coverpant with them as I want adequate coverage for any potential leak spots, and so far, they are the answer... I may look at their AIO for travel in the future, but the one from Gabby's is a solid well made diaper too... good luck on the search,
