No it not because they leak. It because they become damp. Take plastic pants and put it over pullups. Wet once. Wait 30 Minutes feel the Plastic pants. It Damp. Someone, please do a test.As someone who is incontinent, pullups are absolute garbage to me. They leak, they are terrible at containing odor, and I have to take my pants off to change them. There are no cons that outweigh the pros for them.
