This bag is super practical for when you go out since that is where the dirty diapers that are used during the day are placed. It has two compartments in case you want to separate dirty diapers from clean ones. The bag is made of a fabric called Pul that is waterproof and does not concentrate the odor inside the bag and does not emit odors inside the diaper bag. It has a capacity for 3 to 4 diapers approximately.
