10 Best Rooftop Cargo Boxes 2025 in the United States

The MeeFar Car Roof Bag XBEEK is a spacious rooftop cargo carrier with a capacity of 20 cubic feet, making it ideal for large families or extended trips. Its 51” (L) x 40” (W) x 17” (H) dimensions allow it to hold up to 4-6 suitcases, tents, and sleeping bags. The bag is made from 700D PVC tarpaulin, a material known for its durability and waterproof capabilities, ensuring your belongings stay dry and secure even in harsh weather conditions.

The anti-slip mat and 10 reinforced straps help in securely mounting the bag to your vehicle, whether it has a roof rack or not. The soft shell design allows for easy storage when not in use, as it can be folded into a compact size. Security is enhanced with a combination lock, which prevents the zippers from slipping and adds an extra layer of protection for your luggage.

However, the soft shell design might be less aerodynamic compared to hard shell cargo boxes, potentially impacting fuel efficiency. Additionally, the weight of the bag itself is 3.9 kilograms, so users need to consider the added weight when fully loaded. The universal compatibility makes it a versatile choice, but users should ensure that their vehicle can handle the total weight. The MeeFar XBEEK roof bag is a durable and spacious option with good security features and easy installation, but its soft shell design might not be the best for optimizing fuel efficiency.

The SportRack Vista XL Rear Opening Cargo Box is a spacious rooftop cargo box with an internal capacity of 18 cubic feet (510 liters), making it suitable for large families or individuals needing extra storage for trips. Its maximum weight capacity is 100 pounds (45 kg), which should suffice for most typical luggage. The cargo box is made from durable, UV-resistant ABS material, providing longevity and resistance against the elements. Its rear opening design makes accessing items easy and safer, as you don't have to be near traffic when opening it.

The tool-free mounting hardware simplifies installation and removal, making it user-friendly for those who may not be technically inclined. Additionally, the cargo box includes a key and lock system to secure contents and prevent theft, adding a layer of security for peace of mind. It fits various rack systems, including square, round, and most factory racks, ensuring versatility in mounting options.

The aerodynamics of the box are not explicitly mentioned, but the streamlined shape likely contributes to reduced wind resistance and noise. However, users should be aware of the dimensions (63 x 38 x 19 inches) and ensure their vehicle can accommodate its size without obstructing other functions or visibility. At 28 pounds, it's relatively lightweight but sturdy. This cargo box is an excellent choice for those seeking a durable, spacious, and secure storage solution for their vehicle.

The Thule 614 Pulse Cargo Box is a solid choice if you need extra storage space on your vehicle’s roof. It offers 14 cubic feet of capacity, which is enough for gear like 3 to 5 snowboards or luggage for a family trip. At 34 pounds, it’s lightweight enough to handle but still feels sturdy thanks to its hard plastic shell, designed to protect your belongings from weather and road conditions. The box is water-resistant, so your stuff stays dry during rain or snow. Setting it up is quick and easy with the FastGrip mounting system, which securely clamps onto most roof racks without requiring extra tools.

Loading and unloading is more convenient because the box opens from the passenger side, allowing better access in tight parking spots. Security isn’t overlooked either—the central locking system keeps the box tightly shut, and the special Thule Comfort Key only comes out when all locks are properly engaged, giving peace of mind against theft. Its aerodynamic shape helps reduce wind noise and drag while driving, although being 16 inches high means it adds some height to your vehicle, so you should be mindful of low clearances like garages. The 110-pound weight limit suits most typical cargo loads but might be limiting if you need to carry very heavy gear.

This cargo box is well suited for outdoor enthusiasts and families looking for durable, convenient rooftop storage that balances ease of use with security.
