10 Best Car Top Carriers 2025 in the United States

The Thule Motion 3 LTitan is designed for users looking for a reliable and efficient car-top carrier. One of its standout features is its aerodynamic wing-shaped profile, which reduces drag and contributes to better fuel efficiency—ideal for long trips. The sturdy lid design allows for easy one-handed operation, making loading and unloading a breeze. The PowerClick quick-mount system ensures a secure fit, with an audible ‘click’ that signals when it's properly attached, a comforting feature for those who may be new to mounting roof boxes.

In terms of capacity, this large carrier offers ample storage with a volume of 450 liters, suitable for families or anyone needing extra space for gear. It’s made from durable aluminum, promising longevity and good water resistance to protect your belongings from the elements.

On the downside, the weight capacity at 24.04 kilograms might limit how much you can pack, especially if you have bulky items. Some users might find the size a bit cumbersome, making it challenging to handle without assistance when not mounted on the vehicle. Additionally, while the SlideLock system provides added security, it’s crucial to ensure that the lid is locked correctly, as mishaps can occur if not checked. This product suits families and outdoor enthusiasts needing extra space for their adventures, balancing performance with user-friendly features.

The MeeFar Rooftop Cargo Carrier is a soft-shell car roof bag offering a spacious 20 cubic feet of storage, which is enough to hold 4-6 suitcases or camping gear. It measures approximately 47 by 35 by 21 inches, fitting most cars and SUVs whether or not they have roof racks, thanks to its versatile mounting system with 10 reinforced straps and 6 door hooks. Made from heavy-duty, 100% waterproof PVC material, the carrier protects your belongings well against rain and tears, making it reliable for outdoor trips. The included anti-slip mat helps keep the bag stable on your car roof, enhancing safety during travel.

Security-wise, it comes with a combination lock to deter theft, which is a useful feature often missing in similar soft carriers. Weighing around 4.9 kilograms (about 11 pounds), it is relatively light and easy to handle when empty. However, being a soft bag, it may not be as aerodynamic as hard-shell carriers, potentially causing more wind resistance and noise on highways. Also, while its waterproof material is robust, soft bags generally offer less impact protection than rigid carriers.

This MeeFar carrier is an excellent option for those needing flexible, waterproof storage without a roof rack, prioritizing capacity and security over maximum aerodynamic efficiency.

The Thule Motion 3 XXL is a large rooftop cargo box offering 21 cubic feet of storage, ideal for families or anyone needing extra space for trips. It can hold up to 165 pounds, supporting a substantial load for gear or luggage. Made from durable aluminum, it’s sturdy but relatively heavy at 35 kilograms.

Its wing-shaped, aerodynamic design helps reduce wind drag, potentially improving fuel efficiency compared to bulkier boxes. The box mounts easily with the PowerClick quick-mount system, which clicks to confirm secure installation—this tool-free setup is user-friendly, especially for those new to roof boxes. Opening and closing is smooth and can be done with one hand thanks to the wide handle. Security is enhanced with the SlideLock system, which automatically locks the lid and shows when it’s secured, helping keep belongings safe.

However, it is not water resistant, so it is advisable to avoid heavy rain or snow conditions or consider additional protective liners (available as accessories). Its large size means it might not fit all car roofs or low-clearance garages comfortably. This cargo box is suitable for users who prioritize easy mounting, good security, aerodynamic design, and plenty of capacity, while considering its weight and lack of water resistance when planning trips.
