Nûby™ Comfort™ Diapers have an absorbent layer as thin as 3 millimeters, which maintains good absorbency, without pilling or breakage. An innovatively skin-friendly surface makes the diapers feel as silky as purified cotton, while gently protecting baby's tender skin. Breathable material keeps baby's bottom dry through the night. A soft, elastic waistband allows baby to move freely and comfortably.
