Training Pants Done Right!

Our one‐size waterproof shell with removable stretchy side panels creates a comfortable fit, while the replaceable organic cotton pads let your little one learn by feeling wetness. Now your child can pull them up and down when it's time to go, or you can unsnap the side, making messy changes less messy.

Training on the Go?

Flip Disposable Inserts also work inside the Training Pant, so you can enjoy life on the go. Disposables can also be used in addition to the cotton pad to boost absorbency overnight.

Oeko‐Tex Standard 100 certification indicates that bumGenius diapers have been stringently tested and are free from harmful or problematic substances.

These are great if you want to change the look of your existing Flip trainers! People have given negative reviews because they thought these convert regular flips to trainer flips and they don't. However for this mom who bought Noodle (cream) colored pants with Mirror (aqua) sides for my son and now have a very girly girl who is motivated by all things pink, getting a pair of replacement sides was a bargain rather than buy a new pink cover. I only bought one set because they're not THAT cheap. If they were cheaper or ever went on sale I'd buy more to convert the other two Flip trainers we have to "girly" colors. Until then, my girl knows she only gets the 1 pink sided one when it is clean. It still helped motivate her to start wearing the trainers again!


I agree with a previous reviewer. When reading the information for the Flip Potty Trainer I could see that these are only compatible with the Trainer, and not the diapers. But you cannot tell this from reading the information for this product. So for anyone seeing this product and thinking "how cool! The bumgenius/flip system is the best ever, I don't even have to buy training pants!" this is simply not the case. You DO have to buy training pants, even though they easily could have made this compatible with the regular flip covers. This is disappointing, when cotton babies is usually so good.
