Babies can't tell you how they slept or if their nappy was damp. Ordinary nappies can stay damp, but Pampers Baby-Dry are drier faster. For up to 12 hours of undisturbed sleep and nothing but happy babbling mornings. The absorbent Micro Pearls absorb up to 30 times their weight and help lock wetness better. The Top Dry- Layer is always in contact with your baby's skin, designed to dry up as fast as possible whilst the flexible sides provide a comfortable fit for great overnight leakage protection.
