Things to Consider when Buying a Cargo Rooftop Bag

It’s easy to think that all car roof storage boxes are almost the same, but they’re not. There is a lot of ground to cover when deciding to buy one. We are here to guide you into the right direction by bringing to you this simplified guide. Read on to find out the things that are vital in choosing the perfect cargo bag for your vehicle.


Box or Bag?

First, you need to decide whether you want a cargo box or a bag. The box is the most common one you will see is that it is typically made of hard plastic and strong materials. These are a perfect choice if you want a permanent space saver because you are regularly taking a trip. The only cons would be that they are not easy to install, heavier and considerably more expensive than bags.

If you have a soft-sided gear, on the other hand, bags would be a good option. Bags are the perfect temporary solution for those unplanned trips, or you just need a safe space to put some things. They are affordable, easy to install and don’t need a roof rack.



Secondly, you need to gauge the size and number of things you will carry in your rooftop box. While there is no exact way of knowing what size you need, you also need to consider the size of your car. For smaller cars, a big carrier is not advisable. Pick out the right size base on your car and needs. There are a lot of brands that offer different sizes of their carriers.



Hard boxes always come with a lock for security. Bags may come in locks but the same cannot be said about its security. Choose the best one for you based on what you are going to put into the carrier.



The bags are cheaper, and they offer a temporary solution. Boxes, on the other hand, can cost 10 or 20 times as much as the bags. It is always wise to go for the bags if you are not going to use your carrier every so often. On the other hand, the box carrier can be a good investment if you really need one. Just make sure that the price and the value it offers matches.


Ease of installation

Cargo boxes sometimes require two people to install. It is also harder to unmount so it should be uninstalled only when needed. On the contrary, bags offer a tool and hassle-free installation. They are convenient in the way that they can easily be mounted when needed and unmounted just as easily.


Modes of access

Some boxes can be opened on either side allowing for convenience and ease of access. Other models can only be opened on one side which can prove difficult to some but can be preferred by others. Of course, the ones that can be opened from both sides are more expensive therefore choose according to your needs.
