I bought this bcuaese I was moving from Boston, MA to Phoenix, AZ and driving myself and my 2 daughters. I was able to fill this thing to maximum capacity- and was able to fit a small padlock on the zipper to secure it shut. It rained and snowed on our trip and luckily, we had everything already wrapped up in plastic bags this is not a waterproof cargo bag, but rather, water *resistant*. When we got to Phoenix, I noticed that the front part of the bag had frayed and a hole formed. I think this was more do to the straps that were hanging and hitting it than poor craftsmanship. I recommend this bag if you are doing a short trip, but not for long haul trips with a lot of highway driving. Good points: Was able to fill it really well, was very easy to install Not so good: straps really can’t be secured down and end up flapping in the wind
