Car covers are protective coverings designed to shield vehicles from various environmental elements. They help prevent damage from sunlight, rain, snow, and dust, keeping the car's exterior in better condition. Car covers come in different materials, such as polyester and breathable fabrics, to suit various climates and needs. Using a car cover can also deter theft and vandalism by making it less obvious that a vehicle is parked. Many covers are fitted with elastic hems or straps to ensure a snug fit, while some are designed for indoor use, providing protection against scratches and dirt in garages.
