Training pants done right with the bumGenius Flip Training Diaper Cover with Side Panels! A one‐size waterproof shell with removable stretchy side panels that creates a comfortable fit, while the replaceable 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.
