Query: Works for me!

Fastened this to the top of a Nissan Quest. We were a bit worried about the straps. They just don't seem like they will hold the bag while going down the highway, so we also secured the bag with some bungee cords. Everything stayed in place. We filled our rooftop bag with duffel bags full of clothing, air mattresses, sleeping bags and pillows. We wrapped them all in garbage bags just in case of rain, but we didn't encounter any, so I cannot vouch as to whether or not this bag is weatherproof. It is a large bag, though. My mother was playing around with my twin 7-year olds and they all got inside the bag together and folded the top closed. I was shocked to see that they all fit inside!
