The Flip diaper is made by the same company that makes BumGenuis 4.0 diapers but this one is a cover and insert.
I loved the insert. It has guides that make folding to fit very easy. You can also buy Flip disposable diaper inserts that we used in all of our diaper covers for the first few days after birth. I also loved the stretchy fabric and that it seemed to fit my newborn well. It was my favorite for a brief time but that soon changed.
After my baby got a little bigger with more pee and more wiggles, we started having leaks because there are no leg gussets. This was the only diaper cover I really had a leak issue with and it would happen at the leg hole during naps.
