The bungy tie downs make it easy to secure your surfboards to a set of roof bars, they are not designed to be used without a hard rack style roof bar system in place, have a look at our range of soft racks if that's what you are planning to do.
They come in a pouch and pack away very small so if you know you've got a hire car with a roof rack at your destination they are perfect for chucking in the board bag to make it quick and easy to get your boards strapped down when you get to your destination.
