10 Best Roof Bags 2025 in the United States

The Asinking Car Rooftop Cargo Carrier Bag offers a spacious 15 cubic feet capacity, which is enough to carry multiple suitcases, tents, and camping gear, making it suitable for family road trips or outdoor adventures. It’s made from durable, waterproof PVC material with reinforced seams and a thick rubber mat underneath, ensuring it keeps your belongings dry and safe even in harsh weather like rain or snow. The mounting system is versatile, designed to fit most vehicles whether or not they have roof racks, side rails, or crossbars. It uses wide, heavy-duty straps and door hooks with protective pads to secure the bag firmly without damaging your car’s finish, which adds peace of mind during high-speed drives. Installation is relatively straightforward with the included accessories, but the bag requires a car roof at least 50 inches long and 36 inches wide, so it won’t fit smaller or two-door cars.

Although it is a soft-shell bag, meaning it is less aerodynamic than hard-shell carriers, the design still aims to minimize wind resistance and noise. The zippers are large and smooth, making packing and unpacking easier, but soft bags generally don't offer the same protection against heavy impacts as hard cases. This rooftop cargo bag balances good weather protection, capacity, and ease of use for drivers needing a flexible, affordable storage option on the roof. It is not ideal for very small cars or those wanting maximum aerodynamic efficiency, yet it remains a solid choice for many SUVs, sedans, and minivans.

The Car Rooftop Cargo Carrier by Asinking offers a substantial 21 cubic feet of storage capacity, making it suitable for family road trips or camping excursions. Constructed from heavy-duty 840D PVC fabric, it promises durability and weather resistance, with triple-reinforced seams to prevent tearing. The waterproof design is further enhanced by a waterproof zipper and velcro flaps, ensuring no leaks even during heavy rain.

The bag's ease of use is notable, with an anti-slip mat and adjustable straps included for a secure fit on cars with or without roof racks. Additionally, the package comes with door hooks, extra straps, and a storage bag for convenience. However, at 9.33 pounds, it might be slightly cumbersome to handle for some users.

Its aerodynamics might also be a concern for those looking for fuel efficiency, as softer shell carriers can create wind resistance. This product is ideal for those needing a large, durable, and waterproof storage solution for their vehicle.

The Sailnovo Car Rooftop Cargo Carrier offers a generous 20 cubic feet of storage, which can hold several suitcases or camping gear, making it a good choice for families or travelers needing extra space. Its material—durable 1000D Oxford cloth—is thicker and stronger than many competitors, which helps with tear resistance and weather protection. The carrier is waterproof and designed with reinforced seams and wide zipper flaps to reduce water leakage, though it is wise to pack clothes in extra dry bags during heavy rain or extreme weather for added protection.

Installing the bag is fairly straightforward thanks to six heavy-duty tie-down straps and safety hooks, and it fits most cars whether or not they have roof racks. This versatility suits drivers who don’t want the hassle of extra roof racks but still need cargo space. However, it’s not suitable for vehicles with sliding doors or sunroofs, which limits its use for some.

The soft shell design keeps the bag lightweight and easy to fold for storage, but it may not be as aerodynamic as hard shell boxes, potentially causing more wind noise or slightly affecting fuel efficiency at higher speeds. The manufacturer recommends keeping driving speeds under 65 mph. Users should also ensure the zipper is fully closed and secured with the Velcro flap to prevent leaks. The Sailnovo roof bag is a practical, affordable option for adding roof cargo space with strong weather resistance and safety features. It is especially great for those who want an easy-to-store, flexible carrier without investing in a hard box. Just keep in mind its speed limitations, and that it’s not 100% waterproof in all conditions.
