Expert Tip: Pair our Nappy Wrap with flat or fitted nappies and inserts for ultimate reliability and reusability. Simply snap inserts into the shell for quick and easy use. The flaps can be tucked in or left out for full coverage. Using a cover is recommended - you can use one cover for multiple changes as long as the nappy remains clean. For even more sustainability, our fabric is made from recycled plastic bottles, laminated with polyurethane for durability.
