How We Rated
Depending upon the contents and destination, we often switch between using a car roof bag or box for long road trips.
As you can see in the image from a journey from Cardiff to Devon, we securely placed a bag onto the Mercedes’s roof and then passed the straps through the rear doors. However, there are plenty of alternative bags available that can be mounted in a number of different ways to best suit your requirements.
To keep up our commitment to reviewing and testing the latest car roof bags (for this article), we continually upgrade the bags each year. The most recent upgrade was the Thule bag and as you can see in the image, it securely ties down to the roof bars, which makes it much easier to install than our previous bag.


As well as our testing and experience of using multiple car roof bags, we also based our recommendations upon hours of research and a number of factors. Some of the factors that we considered included the storage space, size, ease of installation, compatibility, construction, supplied accessories, warranty and value for money.
Conclusion
Car roof bags are becoming increasingly more popular in the UK and for good reason too. Unlike the rigid box alternative, it’s much easier to store, which is important because it’s where it’ll stay for the majority of the year.
