Of all the AIO's I've ever tried, the only ones I can say I'd BUY again are bum-ware AIO's (just got one of these before my dd potty learned and I wish I'd known about them sooner.. LOVE them) and chumbas super trims(they have a new owner and I don't know when she'll open back up, but these are nice diapers.. just go for a inner that isn't knit because the knits seem to get holes pretty fast .. at least for us)
These two are the only two that I've found that truely work as an AIO for us.. meaning they fit well, are easy to use, and do NOT leak or wick.
A little on down my list but still VERY well loved are our luke's drawers.. these do wick sometimes, so we loved them mostly during the summer without clothing over them (but who wants to put clothing over something so cute anyway?) .. I adore the fit of the candy wrappers and about 90% of the time they stay dry on the outside too. (I'll TOTALLY admit to having a pee holder that floods when she pees though so that might contribute a lot to the little bit of wicking we had)
There are tons of great options out there.. those are just the ones I've decided were our favorites. Have fun!!
