Cute bear illustration bedwetting pants. - Design: Soft material with a bear illustration - Material: 100% cotton - Washing instructions: Machine washable, do not bleach Thank you for viewing. These are pants to be worn over pajamas at night to prevent bedwetting. When my child was 2-3 years old, after graduating from diapers, they wore these over their pajamas every night for a while. There were a few times when they wet the bed, but it didn't spread much to the futon. They are not completely waterproof. There are no noticeable stains, but please understand that these are items stored at home before purchasing.
