ImseVimse Training pants are designed to help children with their potty training. Use the pants during the day to help the child to associate the need to pee with the feeling of wet pants. A great help with toilet training. Since the training pant is not designed to be leak proof it is not recommended to be used during naps. Our new improved model has a snug and comfortable fit and has soft elastic waistband. With three layers of absorbent cotton and one layer of PUL, these training pants protect clothes from getting wet when small accidents happen. Made from 100% organic cotton. Wash and dry inside out.
