10 Best Car Top Carriers 2025 in the United States

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.

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 Car Roof Bag XBEEK is a soft-shell rooftop cargo carrier offering 20 cubic feet of storage space, which is enough to hold 4-6 suitcases or camping gear. Its dimensions (51"L x 40"W x 17"H) fit well on most cars and SUVs, whether or not they have roof racks, making it very versatile. Weighing about 3.9 kg (8.6 pounds), it’s lightweight enough to handle easily and folds down compactly for storage when not in use.

The bag is made of durable, 100% waterproof 700D PVC tarpaulin with tear-resistant grid material, so it protects your belongings well in rain or snow. Installation is straightforward thanks to the included anti-slip mat, 10 reinforced straps, 6 door hooks, and a storage bag, allowing for a secure fit without complex tools. Security is enhanced by a combination lock that prevents the zippers from opening unexpectedly or being tampered with.

As a soft carrier, it may not be as aerodynamic as hard-shell carriers, potentially causing some wind noise or a slight impact on fuel efficiency during long trips. Since it does not specify a maximum weight capacity, it is advisable not to overload it beyond typical luggage weight to avoid strain on your car roof and the bag itself. The MeeFar XBEEK serves as a practical, waterproof, and easy-to-use option for travelers needing extra cargo space without a permanent roof rack, suiting those who want a flexible, budget-friendly solution with solid weather protection and reliable security.
