This Rightline car backpack worked great for us until on one trip we put too much weight in it and didn't use the bottom straps, and one of the top straps came unhooked from the top of the tailgate as we drove on I-95 (I suspect a bump plus the excessive weight plus our failure to use the bottom straps caused the hook to lift free). The dragging along the asphalt before we managed to pull off wore through one end of the bag and damaged one of the bottom frame poles. We have since moved on to a hard shell carrier, but with a little repair and careful strapping, this bag could still work great as a back pack or (perhaps less risky) car top carrier. Alternatively, it could be cut up for the amazing, tough, waterproof vinyl/nylon fabric. Bag has padded handle straps on each end, straps on each end with hooks to hook over top of tailgate or trunk, a long strap to run on inside of tailgate and around back of bag, and straps to hook bottom of bag to underside of rear bumper or frame. It zips open and closed and has a rain flap to cover the zipper all around. It even has a little pocket with a clear back in which to insert your car license plate (which would otherwise be hidden by the bag when hung on the back of the car).
