Bambo Nature Baby Diapers offer comfortable overnight protection for your baby. Designed for unisex wear in size 4 (for babies weighing 15 to 31 lbs), these disposable diapers feature a unique channel technology that quickly absorbs large volumes of liquid. This helps keep your baby dry and comfortable throughout the night. Bambo Nature diapers are also gentle on sensitive skin. They are certified skin-safe, eco-friendly, and free of harmful chemicals and allergens. Flexible leg cuffs and a comfortable waistband provide a secure fit that stays in place even through wiggling and nighttime movement.
