Large capacity. 44"L (111.76cm) x 34"W (86.36cm) x 17"H (43.18cm) 15 cubic feet (0.43 cubic meter), It holds two golf bags and luggage. You will never make it look like the marketing photos but it is thick and durable. The front flap could use velco because it acts as an air dam and catches the wind. It is definitely waterproof! Water proof PVC material. The durability of the carrier was tough and felt all aspects of it were made with quality. On the roadtrip even you we met ome snow and rain and it has no issue. All of the interior contents remained dry and unaffected. Accessories included. It has it's own storage bag, anti-slip mat and 4 door hooks. The cargo carrier is easy to fold up and fit back in the bag to put away. Cargo roof bag can fits all vechicles with or without racks. Zippers are easy to zip and watertight. Great for long trips. Cargo roof bag is a great alternative to the hard shell containers. Would totally recommend to anyone needing to transport a large amount of stuff for a roadtrip and free up the inside of the vehicle. Easy to install and foldable. Straps held up, weatherproof seals on car windows weren't affected at all. it also creates additional space where you can store everything you need while travelling. It is good for families or travellers.
