Absorbent micro pearls absorb up to 30 times their weight. Stretchy sides adapt to the baby shape and movements and provide a comfortable fit for reliable leakage protection. Top dry-layer is in constant contact with baby's skin, designed to pull liquid away and dry up as fast as possible. Extra sleep-layer quickly absorbs the wetness and spreads it evenly across the core. The breathable outer cover helps baby's skin breathe.
