Repairs on all Clover Brand diapers and wool covers are free for the life of the diaper. Should any repairs be necessary within the first 90 days of purchase, Precious Dignity will pay the shipping costs. Shipping to and from Precious Dignity for repairs after the first 90 days is the responsibility of the owner. This warranty is effective for all owners of the diaper, both original and second-hand. No proof of purchase is necessary. Please note: The Large Wool Pant is very generously sized. The Small Pant will work for both small and small/medium sized Clover diapers. The Medium Pant will work for both small/medium and medium Clover Diapers. The new Medium/Large size will work well for large Clover diapers. The large is best for very hard-to-fit babies and young special needs children.
