Standing leakage barriers and our flexible side panels make for a super comfortable leak free fit. Included is a urine-sensitive strip that runs the length of the diaper to indicate when it's time to change the diaper (yellow to blue). All the materials selected for this diaper has been evaluated minimize harmful effects on the environment while being baby skin safe.
