I have tried a lot of diapers over the past couple of years and want to know if the diaper of my dreams is out there and I just haven't found it yet. We primarily use prefolds or workhorse fitteds and covers and love them, but a great one-piece dipe can make things much easier for out of the house, with babysitters, and with my mom, who can't ever get a 2-piece system on right. Here are the criteria in order of importance:
1. 100% cotton interior (no polyester in the absorbent part)
2. no stuffing or unstuffing
3. easy to spray poop off of, washes well
4. dries relatively quickly
5. velcro closure, though I would do snaps if the other criteria were met
I think sized dipes fit better, but don't mind one-size if they are good in the other categories. Here is what I have already tried and sold: fuzzibunz sized and one-size, bumgenius one-size pockets, bumgenius elemental organic AIO, bummis easy-fit pockets, and thirsties duo pocket diapers.
