Advanced Core Structure of SAP
Our diapers ensure effective overnight absorption and dryness using a high-performance core composite of SAP (super absorbent polymer) structured with targeted ratios of urine volume.
360° Leak Guard Design
Our unique 360° leak-guard system employs double-layer elastic barriers gently hugging the baby’s thighs. They are soft and snug to wear without any harmful marks.
No Backflow and Skin Friendly
With intelligent SAP allocation and efficient flow paths, a strong gel layer is formed that locks moisture and resists pressure. Scientifically proven to keep the skin dry and reduce the risks of diaper rashes.
