The WeatherTech® RackSack™ expands your cargo carrying capacity a whopping 13 cubic feet (measures 39" x 32" x 18"). Made of durable water repellent polyester, the RackSack™ stows away neatly in its own bag. Features include swivel straps that mount to the crossbar or side rails of an existing roof rack, patented Roll and Wrap™ tabs to prevent flapping straps, and a soft felt bottom to protect your vehicle's finish from scratching.

PLEASE NOTE: For use only in conjunction with a cargo rack.
