Rain covers are protective materials designed to shield items from rain and moisture. They are commonly used for outdoor furniture, vehicles, and equipment to prevent water damage. Made from waterproof or water-resistant fabrics, rain covers help keep belongings dry and extend their lifespan. These covers come in various sizes and shapes to fit different objects, such as bicycles, tents, and patio sets. Many rain covers are lightweight and easy to store when not in use. Some even feature adjustable straps or elastic hems to ensure a snug fit, providing added protection against wind and heavy rain.
