Differences Between a Roof Bag and Roof Box

Car Roof Box

Car roof boxes are secure and and usually include a locking system so you can ensure your valuables are safe if you have to leave your vehicle.

The strong, hard shell adds an additional layer of protection. This casing also goes a long way to protect your belongings from harsh weather conditions and moisture.

When you’re on the road you can think of your roof box as an additional car boot, with your contents protected from impact.

Car Roof Bag

The big advantage of a car roof bag is storage. They take up a lot less than a car roof box as they can be folded and stored away without taking up much room.

You will also find most roof bags are far easier to install than roof boxes. For the majority of roof bags you don’t need to install a roof rack to mount it.

Roof bags are generally much cheaper than a roof box – in addition you don’t need to outlay on a roof rack for the mounting.

Bags are generally more versatile for housing any oddly shaped items.

Although car roof bags are by nature not as weatherproof, many current ones do offer a good degree of protection against the elements.

The same can also be said of security – many of them now have excellent features to ward off any unwanted attention!

Let’s summarise those key differences:

Roof Box Vs Roof Bag

Space Capacity

They offer a very similar volume capacity of space for your belongings with roof boxes shading it.


Roof boxes offer enhanced security due to their hard shell. Although roof bags have improved greatly with security features they can still be accessed with a knife for example.

Storage Size

Roof bags are advantageous here if you are short on space or don’t have a garage. They can be folded up and tucked away in a tiny space. Some people who have a roof box leave it on the car but two things to mention: they greatly increase fuel consumption and might be a problem with low bridges (depending where you live!)


If you have a budget on the smaller side then roof bags are generally the best option. Of course you can find some roof bags that are cost more than roof boxes and vice versa but generally the bags can save you money.

I hope this list of the best car roof bags was helpful.
