Proraps began in 1987 using Velcro closures instead of the standard plastic pull-on pants. Proraps Classic Diaper Covers are the most common cloth diaper cover used around the world. The newborn size features an umbilical scoop to give baby time to heal without a cloth diaper cover rubbing against the healing area. These cloth diaper covers work with fitted cloth diapers and prefolds. Thanks Mama offers Proraps in white and in colors.
