Know that regular fleece will not provide the waterproof protection necessary for cloth diapering. Fleece covers and longies for cloth diapering are most effectively made from Malden Mills fleece as these covers are. Malden Mills is the fleece used for high quality active and outerwear and cannot be purchased at ordinary fabric stores. There are a number of websites online that sell it by the yard, and it is well worth the extra money.
I would rate these covers a 9 – 9.5.
