Step-up Insert

The perfect insert if your super hero requires more absorbency for either nighttime or daytime. Designed to be used with either the Brain Trainer or Waterproof Undies, these inserts add a varying amount of additional protection and absorbency. Size 1:       For Brain Trainer Bedwetting Pants and Waterproof Underwear Sizes Small and Medium Size 2:     For Brain Trainer Bedwetting Pants and Waterproof Underwear Sizes Large and XL    The difference between the Soaker Bombs and the Step-up Inserts are two-fold.  1. Layers - Soaker bombs are 3 layers, folded in half for a whopping 6 layers of microfiber absorbency when folded in half, While Step-up Inserts are 2 layers. 2. Shape - Step-up Inserts have a contoured shape to them, making them lay trimmer and more natural in the underwear. If you want to stack two inserts, the step up inserts will give you a better fit.
