6: Rightline Cargo Bag

we have this fantastic extra large waterproof cargo carrier bag from Rightline.  It's completely weatherproof, capable of protecting your luggage from rain, wind, and snow.

If you're driving through extreme weather, then you need the Rightline Cargo Bag.

It features a UV-protected PVC XT semi-coated mesh material. It's strong enough to withstand impacts from debris on the road and soft enough to fold up for storage at home.

Other features include:

  • Universal fit for all cars, trucks, and SUVs
  • An extra-large waterproof carrier bag with UV-protected material
  • Straightforward installation process
  • Welded seams for increased durability

Are Rooftop Bags Waterproof?

Are Roof Top Cargo Bags Safe?

As long as you properly install them, waterproof rooftop cargo carrier bags are 100% safe. You should know some best practices to keep things safe with your cargo. Here are a few guidelines to follow:

  • Use door hooks to attach straps instead of fastening them to the interior of your car. If you have straps dangling down through the inside, they could interfere with your airbags deploying. To stay safe, make sure that no straps are dangling through the interior of your car.
  • Pay close attention to the roof weight limit of your vehicle. Every vehicle is different with how much weight they can transport on top. Most cars have a weight limit of 100 to 160 pounds. Weigh your cargo before putting it on the roof to doubly make sure. If you're carrying too much weight, you could offset the balance of your vehicle and cause an accident.
  • Follow the directions related to roof racks. Lots of waterproof rooftop cargo bag options will work with or without a roof rack. Yet, they will have different installation methods for both. It's imperative to follow the directions for each technique closely. If your roof bag is installed incorrectly on your roof rack, it could fall off, ruining your cargo.

Can You Put a Roof Bag on a Sunroof?

For the most part, vehicle manufacturers don't want you to put cargo bags on sunroofs. There's a good reason for this, as excessive weight can ruin a sunroof.

If your cargo bag doesn't have a protective mat, the damage can become even worse. The last thing that you want, as sunroof repairs are costly.

So does that mean that you can't carry more cargo on vehicles with sunroofs? Not at all. The best thing you can do is install a roof rack. That way, you can have cargo bags, and they won't make contact with the glass on your sunroof.

A roof rack will allow you to choose from soft cargo bags and hard-shell cargo boxes. To learn more about the differences between the two, check out this comparison that we did.

Another option for sunroof owners is to go with a hitch-style cargo carrier. As long as you have hitching capabilities, you can transport your cargo from behind your car instead of on top.

While some models of soft cargo carriers claim that you can use them on the sunroof, it's better to be safe than sorry

Another massive benefit of this cargo bag is its pricing. At the meager price of $44.99, it's one of the most affordable bags on the market. It's also very high-quality, so it's a great deal for the price.

A roof rack is required for this model. So if you don't have crossbars or a roof rack, you'll need to get one before you can use it. While this may deter some users, roof racks are relatively inexpensive and easy to install.

Fifteen cubic feet of storage space will give you plenty of room to store everything you need for your vacation. Suitcases, swimwear, flippers, goggles, and so much more will easily fit into this carrier.
