Waterproof panel
Potty training underwear feature an inner hidden waterproof "accident panel" to prevent accidents from soaking through clothing quickly. Waterproof material that is sewn in stops baby from leaking when they have an accident, and potty training pants fit perfectly around kids' thighs, with no elastic marks at all. Your baby peed in it and the wetness stayed in. This gives your little one time to make it to the potty if an accident occurs.
