Many of us use our cars to travel, but not all cars have enough cargo space to hold all of the items we need for travelling. Finding a space to put your needed belongings can be stressful—especially if it means you can’t bring everything you need or you have to stuff your car.
Cargo accessories for cars were developed to combat this struggle. With a cargo box or bag, you can attach a new area of available storage space to your vehicle. This can even double the maximum holding capability of your vehicle!

Cargo boxes are typically made of hard plastic that mounts onto the roof of your car. However, they can look pricey and intimidate at first glance. A great alternative to the cargo box is the cargo bag. Rather than plastic, it is made with weatherproof material, making it more affordable and practical.
A cargo bag is a very efficient and cost-effective way to add storage space to your vehicle. A favourite of customers is the Keeper Waterproof Cargo Bag. It retails for about $50. Below is a review of the Keeper Waterproof Cargo Bag.

Technology
This cargo bag has a flexible skeleton that makes it dynamic. It can be folded up to a small, flat size and stored away for maximum convenience if it’s not in use. This flexible material also allows it to fit any cargo, even if it has a weird shape or size. The bag will move to the shape of whatever you place inside of it.
The Keeper Waterproof Cargo Bag attaches to the roof with buckles. This process is speedy and easy. You elongate the buckles. Then, you lift the bag onto the roof and mount it. After that, you snap the buckles shut and tighten them. You can adjust the sizes of the buckle system depending on the roof rack you have.
Design
The Keeper Waterproof Cargo Bag is made of rubber-laminated nylon. This nylon is not only waterproof, but it also protects from road grit, the sun, and the wind. It is a durable fabric that is designed for maximum protection and weather resistance. The overall size of this cargo bag is 44 x 34 x 17 inches. It folds and flexes to fit even the largest and most weirdly shaped items.
This cargo bag is designed to fit any roof racks with attachment capabilities on all four sides. If a roof rack has less than four capable sides, the product needs to be tested before use to ensure maximum security, as the attachment may not be as sturdy.
