We designed our durable, water-resistant hammock seat cover specifically for the dirtiest dogs. Crafted of heavy-duty polyester, the protective hammock features a water-resistant coating on both sides to ensure that no moisture gets through to your vehicle’s upholstery. A grippy, slip-resistant surface on the bottom keeps the hammock in place. The easiest way to keep your car seats clean and dry! Quick and easy to install. Adjustable headrests required for installation. Polyester. Hose off or spot clean. Imported.
