Used about 3 times for camping (first photo). I'm selling it because I no longer need it after switching from an SUV to a minivan. It comes with four straps. I only used two of them; the other two are unused. The following is quoted from the purchase site: * Durable design with double waterproof PVC coating. Protects luggage from UV rays, rain, wind, and sand. * Eight adjustable straps prevent luggage from slipping. * Can be folded compactly. * L size: 420L Approximately 120cm x 76cm x 46cm (Weight: approximately 525g) * Installation instructions are not included.
