The Rightline Gear Car Back Carrier is a patented cargo bag that attaches to the rear of your vehicle, WITH or WITHOUT a roof rack. The perfect solution for those who engage in paddle sports, snow sports, or cycling. Keep your gear on the roof and your cargo on the back! The location of the Carrier allows for easy access and also shields it from the wind, saving you $$$ at the gas pump. The Carrier is made from UV protected PVC Semi-Coated Mesh XT for maximum durability. The bottom pole frame provides structural support for the cargo in the bag. The Rear Car Clips attach the Car Back Carrier to the rear hatch door on vehicles without a roof rack.
