Thule

You'll never get caught unprepared with Thule's expandable Tahoe Rooftop Bag and its impressive 15 to 17 cubic foot carrying capacity. It easily attaches to most aftermarket and factory racks and features a durable weatherproof construction with taped seams to keep your goodies safe and dry. The Tahoe also uses strategically placed handles for easy transport and an internal foam construction to help the bag maintain shape. Plus, it conveniently collapses into its own storage bag.
