Yakima DryTop is a weather-resistant (not totally waterproof) cargo bag for your rooftop. This is a great option if you need extra luggage space and don't have a roof rack - the DryTop mounts directly to your roof. You can also use this bag with existing roof racks, or drop it onto a cargo basket! 

 

Provides 16 cubic feet of storage (40" x 38" x 18")
