12-17kg nappies, which thanks to the unique 3-way protection system, offer up to 12 hours of total leakage protection, as liquids are absorbed immediately and leakage at the waist and legs is prevented. The super-absorbent core absorbs liquids instantly, the safety cuffs prevent leg leaks and the stretch side wings ensure a comfortable fit. So they offer excellent protection against leaks, no matter how much your baby moves around. Baby's safety is the top priority. The diapers are 100% safe, clinically and dermatologically tested and certified by the independent OEKO-TEX institute.
