Bag for a Car Roof Buying Considerations
When you’re trying to buy the best car roof bag, there are many things you should keep in mind during the process. We’ve listed the three most important ones below, but you should also consider things like pricing, warranties, form and more.
Security and Mounting
Mounting the car roof bag involves accounting for a combination of both the bag’s dimensions when full and the applicable security measures that are needed to make sure the bag stays on the roof of your car. You should consider not only the loaded dimensions of the bag but also the number of fastening straps and the method of fastening they use. More straps usually increase security for your luggage, but also tend to take longer to fasten and secure the bag to the vehicle in the first place. Additionally, most bags secure better to a roof rack system than without.
Security and stability tie right in with mounting. If you get a large, waterproof car roof bag that you cannot fasten to your roof or otherwise secure at all, then there’s simply no point in having it because you won’t be able to use it. You can find car roof bags that don’t require a car rack to be used, but generally having a roof rack increases security regardless. Additionally, you can get a non-slip roof cover.
Carrying Capacity
While there are several important factors to consider when buying a car roof bag, the carrying capacity or storage capacity is arguably one of, if not the, most important factors. The entire point of buying a roof bag, to begin with, is to provide you with extra cargo space, so you need to buy a cargo bag that is big enough for your additional belongings, but is also manageable enough to fit on the roof of your vehicle.
Generally speaking, you will mostly find the carrying capacity of your bag measured in cubic feet, which can be misleading because that’s a measurement of area, not weight, and doesn’t always give you an accurate estimate of the shape or dimensions of a fully stocked bag. If you can read the reviews to find carrying weights, you should, as it will give you a better idea of what you can and can’t expect out of the bag.
Materials and Waterproofing
The quality of the materials used to construct your car roof bag is incredibly important, as they have to be durable and capable of enduring a variety of weather conditions to protect your belongings. Many brands will claim that their bag material is waterproof, or will use the term waterproof in their advertisements of the product.
This is not always true, and a more accurate phrase would be to say that the bags are water-resistant. The difference between the two can be found in particularly heavy rains, where a waterproof bag will reject the water continuously, and a water-resistant bag tends to give in under the pressure.
Keep in mind that artificial materials tend to endure better over longer periods in any weather conditions than natural fabrics. Also, look for products that are coated with PVC either inside or out, if not both where available, as this will aid in waterproofing your bag.
The Final Word
Although roof bags may be viewed as not as sturdy and robust as their roof box counterparts, there’s still lots of great options out there that won’t let you down on your trips. We’ve selected 5 of the best car roof bags that are guaranteed to protect all your belongings for long car journeys.
