Huggies diapers have the Breathe Dry System -- a highly breathable cover that lets fresh air in to help keep baby's skin dry. Meanwhile, the Leak Lock System quickly draws moisture away from baby's sensitive skin into the absorbent core to help stop leaks and keep baby happy. Only Huggies Snug and Dry diapers have all-around stretch for a super-snug fit. Plus new LeakLock captures moisture better than before.
