Pampers Swaddlers Ultra are the most absorbent Swaddlers diapers designed for all day and all night protection. Size 6 diapers fit babies weighing 23-44 pounds with 120 diapers per package. These premium diapers feature a KeepDry Liner that wicks wetness and mess away from skin, pillowy soft materials for comfort, and an extra absorbent core that provides better absorbency than other day and night diapers offered in club stores.

Pampers Swaddlers are dermatologically approved by the Skin Health Alliance, hypoallergenic, and free of elemental chlorine, parabens, and latex to protect babies' sensitive skin. The All-Around LeakGuard with Blowout Barrier provides up to 100% leak and blowout protection to keep baby dry and comfortable. These diapers feature stretchy sides for a secure fit and a wetness indicator that changes color when baby may need a diaper change.
