One thing you may or may not have given much thought is the fuel economy of your vehicle when you add a bulky roof bag to it. The added wind resistance will likely drop fuel efficiency by multiple miles per gallon. Roof boxes are great if you need to carry more stuff than you can fit in your car. Read our guide for the lowdown on what you should consider before buying one! Which rooftop cargo bag is best for you really comes down to how much use you plan on getting out of it. If I were to be driving a lot and long distances, the Roofpax would give me the most peace of mind with all of its safety features.The bag has a light reflection logo at night which I think is a really smart feature too. The quality of this bag is military-grade and the specs all around are very compelling. style>
