bumGenius Original

{ one-size, pocket-style cloth diaper }


The original bumGenius pocket design released in 2005, put bumGenius on the map as one of the best‐selling cloth diapers in the world — and this top‐rated cloth diaper just got even better! With an updated stay‐dry inner fabric that stretches to provide a secure fit and a redesigned pocket that is more trim across the back, the bumGenius Original 5.0 also includes the same patented features that make bumGenius so genius! Adjustable sizing, snap closures and two inserts for customized absorbency make this a diaper for all needs: day or night, light or heavy wetters, small or big babies.

This was my husband's first cloth purchase believe it or not and I LOVE it. It purchased Ballet I believe it's called (pink and grey) the colors are amazing it looks great can't wait to get it on her!


I have been cloth diapering for a year now, and the vast majority of my stash are BumGenius 4.0s. They're a great diaper, and I plan to use them on my next baby due in the spring. I have purchased 2 new of the new 5.0 diapers about 3 weeks ago. The color (Pepper) is gorgeous and vibrant. Other than that, I see no difference between the 4.0 and 5.0. I know changes have been made to the fabric and elastic, but I see no difference between them at all. That said, I'm very happy with the 5.0, not because it's an improvement over the 4.0, but simply because it, like its predessor, continues to excel. I highly recommend both the 4.0 and 5.0 equally.
