The MeeFar Car Roof Bag XBEEK Rooftop Cargo Carrier Bag offers ample storage space with its 20 cubic feet capacity, making it suitable for large trips where you need to carry multiple suitcases, tents, or sleeping bags. Its dimensions are 51” (L) x 40” (W) x 17” (H), providing a spacious area for a variety of items. Constructed from 700D PVC tarpaulin, the bag is both waterproof and tear-proof, ensuring durability and reliable protection for your belongings in various weather conditions.

The soft shell design allows it to be folded and stored easily when not in use, which is a space-saving feature. It weighs 3.9 kilograms, making it relatively lightweight for its size and capacity. The universal compatibility means it can be used on any car or SUV, whether or not they have a roof rack, adding to its versatility. Installation is straightforward with the included anti-slip mat, 10 reinforced straps, and 6 door hooks, which provide a secure attachment.

Additionally, the included combination lock enhances the security of your belongings by preventing the zippers from slipping. The aerodynamics of the bag might not be as efficient as hard-shell carriers, potentially affecting fuel efficiency. Despite being waterproof, the bag might still be prone to some water seepage in extreme weather conditions. This rooftop cargo bag is a solid option for those who need flexible and spacious storage for their car trips, especially if they want a lightweight and easy-to-store solution.

The Thule Force 3 - Size L Sport rooftop cargo box is an excellent option for those needing extra storage space for trips or active lifestyles. With an 11 cubic feet capacity, it provides ample room for luggage, sports equipment, or camping gear. Its dimensions (approximately 75 x 25 x 17 inches) offer a narrow design that helps reduce wind resistance when driving, enhancing fuel efficiency compared to larger boxes. Weighing around 30.7 pounds, it is reasonably light for its size, making installation and removal straightforward.

Durability is a strong point, as the box is made from tough plastic designed to endure daily use and harsh weather, and it is fully waterproof to keep belongings dry. The mounting system is user-friendly and secure, featuring a quick-attach mechanism with a clear click indicator to confirm the box is safely locked onto the vehicle’s roof rack. A notable feature is the dual-sided opening, allowing access to cargo from either side of the car, which is especially convenient in tight parking spots or busy areas.

Security is enhanced with the SlideLock system that automatically locks the lid and provides a visual indication when securely closed, helping to prevent theft or accidental opening during travel. This cargo box is compatible with SUVs, trucks, cars, and electric vehicles, making it highly versatile. It suits users seeking a reliable, aerodynamic, and secure rooftop carrier that balances size and convenience without excessive bulk. For carrying very large or heavy items, checking the vehicle’s roof rack weight capacity and considering a bigger or specialized carrier is advisable.

The Thule Motion 3 XXL rooftop cargo box is a spacious and well-designed carrier ideal for families or anyone needing extra storage space on top of their vehicle. It offers a generous 21 cubic feet capacity and can hold up to 165 pounds, which suits most gear from luggage to sports equipment. Measuring about 96 by 39 by 20 inches, it’s quite large, so make sure your vehicle can accommodate its size. The box is made from durable aluminum, providing a strong and lightweight shell that helps protect your items. Its aerodynamic, wing-shaped design with a forward-leaning nose reduces wind drag, which can help improve fuel efficiency compared to bulkier carriers.

Mounting is straightforward thanks to the PowerClick quick-mount system, which signals when it’s securely attached, making installation faster and tool-free. Opening and closing the lid is easy with one hand, aided by a sturdy lid and wide handle, which adds convenience when loading or unloading. The SlideLock system enhances security by automatically locking the lid and showing when it’s properly closed, giving peace of mind that your belongings are safe. However, the box isn’t water resistant, so it’s best used in dry conditions or with waterproof bags inside. At 35 kilograms (about 77 pounds), it’s relatively heavy for installation, so some users may need assistance mounting it.

The box comes in a neutral titan color and offers optional accessories like interior lighting and protective liners, which are sold separately.
