A wet bag is a waterproof storage solution designed to hold damp or soiled items, such as cloth diapers, swimsuits, or gym clothes. Made from materials like PUL (polyurethane laminate), these bags prevent moisture and odors from escaping, making them ideal for parents and active individuals. Wet bags come in various sizes and styles, often featuring a zipper or snap closure for easy access. They are reusable and eco-friendly, reducing the need for single-use plastic bags. Many people use wet bags in conjunction with diaper bags or beach bags for added convenience and organization.
