Upairy's potty training underwear bridges the gap between diapers and big-kid underwear. Made of soft 103% , each pair feels gentle and natural on a toddler's skin. Inside, a secret absorbent core and waterproof lining provide a little “cushion” against accidents – enough to hold spills but not a full diaper. This layered design (similar to other cloth trainers with four layersthebump.com) lets kids feel wetness and learn from it, without soaking through outer clothes. The result is a comfortable, leak-resistant training pant that helps toddlers master the potty.
