Covers are exactly as the name suggests – just the cover. This cover wrap around the other absorbent layers to form the waterproof outer layer that keeps moisture in but still allows airflow. There is no lining sewn onto the inside of the nappy as in the case of pocket nappies. a-Tooch-a-Licious covers have double gussets to provide gentle, yet secure leak protection. These covers are usually used with fitted nappies and flats/prefolds that will completely wrap around baby’s bum.
