How to tie-down the RoofPax rooftop cargo bag?

The RoofPax rooftop cargo carrier bags have 10 sturdy tie-down straps all around the roof bag, 3 on each side and 2 in the front and back. This allows the bag to be strapped down securely to either a roof rack, raised side rails, or to cross bars. In case you have neither of the above – you can always use the included RoofPax door hook straps.
