Pampers Baby-Dry Night Nappy Pants offer up to 12 hours of all-around extra leakage protection for a peaceful night's sleep. This is because they now have a revolutionary Stop & Protect Pocket to help prevent leaks at the back, and compared to Pampers Baby-Dry pants, offer a strengthened core that absorbs more. Just like you, Pampers put your baby’s safety first: Pampers Baby-Dry Night Nappy Pants are dermatologically tested, contain 0% EU perfume allergens (as regulated in the EU Cosmetics Regulation No 1223/2009) and are tested and certified according to Standard 100 by Oekotex.
