Executive Technical Summary: Nighttime diaper leaks disrupt infant sleep cycles and cause parental frustration, driving high demand for dedicated overnight diaper SKUs.
Overnight diapers require twice the absorption capacity of daytime diapers without ballooning into an uncomfortable, heavy mass. We achieve this via a dual-core architecture: an upper rapid-acquisition core paired with a high-retention lower core containing high-AUL Sumitomo Seika SAP.
