This three layer microfiber insert generously increases the absorbency of your undies. It can be used length-wise to "step-up" the overall absorbency of any pair of Super Undies or set off a "soaker bomb" by folding it in half and using it only in front, where boys need it most!
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.
