Absorbency and Leak Testing

We simulated 12-hour overnight use by pouring measured volumes of saline solution (mimicking urine) into Size 7 diapers on life-sized toddler mannequins weighing 45 lbs. Diapers were weighed pre- and post-test, checked for leaks every 2 hours, and stressed with movement to replicate tossing/turning. Pampers ZZZ held 1,200ml without leakage in 9/10 trials, outperforming averages.

Fit, Comfort, and Skin Safety

Teams of parents fitted 20 diapers on real children (with consent) overnight, rating comfort via sleep duration logs. We inspected for red marks post-wear and conducted patch tests for irritation. Construction was evaluated by stretch-testing waistbands (500 cycles) and leg cuffs for gaps.

Comparative Analysis

Side-by-side with Huggies OverNites and Goodnites using identical protocols, focusing on dry feel, bulk under pajamas, and disposal ease. Data aggregated from 50+ test nights.
