A diaper cover is a waterproof or water-resistant garment worn over a cloth diaper to prevent leaks and protect clothing. Made from materials like PUL (polyurethane laminate) or wool, these covers help keep moisture contained while allowing the cloth diaper to absorb waste. They come in various sizes, styles, and colors to fit different needs and preferences. Diaper covers can be used with various types of cloth diapers, including prefolds, fitteds, and flat diapers. They are adjustable, often featuring snaps or hook-and-loop closures, ensuring a snug fit. Many parents choose diaper covers for their eco-friendliness and cost-effectiveness compared to disposable diapers.
