10 Best Cargo Boxes 2025 in the United States

The Thule Motion 3 XXL rooftop cargo box offers a large 21 cubic feet capacity, making it a great choice for families or anyone needing extra storage space on road trips. Its aluminum shell is sturdy and durable, but it’s not water-resistant, so it’s best to avoid heavy rain or snow exposure. The aerodynamic, wing-shaped design helps reduce drag, which can save fuel and reduce wind noise compared to bulkier boxes.

Installation is straightforward thanks to the PowerClick tool-free mounting system, which signals when it’s securely attached, making setup quick and stress-free. The wide handle and one-handed operation allow for easy opening and closing, and the SlideLock system adds a layer of security by automatically locking the lid and showing when it’s properly closed. However, at 35 kilograms, it’s quite heavy, so lifting it onto the roof might require some effort or an extra pair of hands.

This cargo box is well-suited for those who prioritize capacity, ease of use, and aerodynamic efficiency. If you need full water protection or a lighter option, you might want to explore other models. Accessories like an interior light and protective liner are available but sold separately.

The Thule 613 Pulse Cargo Box Alpine in black is a functional and durable rooftop cargo box providing an additional 11 cubic feet of storage space. It's particularly beneficial for those who frequently carry items like skis or snowboards, as it comfortably fits 4-6 skis or 3-4 snowboards. One of its standout features is the FastGrip quick-mount system, which allows for easy assembly in just a few minutes.

The passenger-side opening makes loading and unloading more convenient, and the Central Locking system enhances security, ensuring that the Thule Comfort Key can only be removed when all locking points are securely closed. The cargo box is made from rugged plastic, offering durability and protection for your belongings.

Its dimensions (88.5 x 25.5 x 12.5 inches) and weight (30 lbs) make it a solid choice for those needing extra storage without adding significant weight to their vehicle. However, its size might be a limitation for smaller cars, and while it is water-resistant, it may not be fully waterproof in extreme conditions. Additionally, since it only opens on one side, it might not be as accessible from both sides of the vehicle. With a load capacity of 110 lbs, it supports a decent amount but be sure not to exceed this limit to avoid damage. For those looking for a reliable and easy-to-use cargo box, the Thule 613 Pulse Cargo Box Alpine is a strong contender.

The aerodynamic shape helps reduce wind resistance and noise while driving, which is a big plus for long journeys.

Made from durable plastic, it’s built to handle daily use and various weather conditions with a water-resistant design, although it may not be fully waterproof in heavy rain.

The mounting system is straightforward, and a simple click lets you know the box is securely attached. Security is well-covered through the SlideLock system, which locks the lid and clearly indicates when it’s closed properly, giving peace of mind that your belongings are safe. At 66 pounds, it is reasonably lightweight for its size, making installation manageable for most users.

The cargo box ranks well among hard-shell carriers and is known for strong customer satisfaction.
