Review: Mockins XXL 50 Cu Ft Waterproof Rooftop Cargo Carrier Bag

Needing extra space for travel, especially on long road trips or when heading out with the family, used to be a constant struggle for me. Packing light seemed impossible, and trying to cram everything into the car’s trunk and back seats just led to cramped passengers and obstructed views. This problem wasn’t just an inconvenience; it made journeys stressful and less enjoyable, potentially impacting safety with overloaded or poorly packed vehicles. Solving this need for additional storage without resorting to a larger vehicle or leaving essentials behind became a priority.

Anyone planning a road trip, camping adventure, moving, or simply needing more cargo capacity than their vehicle’s interior provides will likely consider a rooftop cargo carrier. These versatile storage solutions free up cabin space, making trips more comfortable for passengers and allowing you to bring along all the gear you need. The ideal customer is someone who frequently travels with significant luggage, outdoor equipment, or supplies, and who wants a secure, weather-protected way to transport items on top of their car.

However, a rooftop cargo carrier might not be the best fit for someone who rarely travels, has minimal luggage, or primarily drives in urban environments where the added height and potential wind resistance could be bothersome. For very small vehicles with low weight limits or no compatible rack system (though many soft-shell carriers can adapt), alternative solutions like hitch-mounted carriers or simply packing lighter might be better. Before purchasing, consider the carrier type (soft-shell bag vs. hard-shell box), your vehicle’s roof setup (bare roof, side rails, crossbars, or a platform rack), the required capacity, ease of installation and removal, material durability and waterproofing, and included security features.

Introducing the Mockins XXL 50 Cu Ft Waterproof Rooftop Cargo Carrier Bag

Having navigated the challenges of packing for numerous trips, I discovered the Mockins XXL 50 Cu Ft Waterproof Rooftop Cargo Carrier Bag. This product promises to transform your vehicle’s roof into a massive, weather-resistant storage area. It’s an extra-large soft-shell cargo bag designed to fit a wide range of vehicles, offering a substantial 50 cubic feet of space. When you purchase it, you get the robust vinyl bag itself, a comprehensive set of accessories for various mounting options including adjustable ratchet straps, durable buckle straps, door and trunk hooks, an anti-slip mat to protect your car’s roof, a combination lock for security, and a convenient carry bag for storage. This specific car roof bag is really for anyone who needs serious cargo capacity and versatility, working with or without traditional roof racks. It’s perhaps less suited for those needing minimal space or prioritizing the rigid security of a hard-shell box. Compared to smaller bags on the market, its sheer size sets it apart, offering capacity rivaling some hard-shell options but with the flexibility and easier storage of a soft bag.

Here’s a quick look at some pros and cons:

Pros:
* Massive 50 cu ft capacity
* Highly versatile mounting options (fits racks or bare roofs)
* Robust waterproof features (vinyl material, double-sealed zippers, large flap)
* Complete accessory kit included
* Anti-slip mat protects vehicle roof

Cons:
* Its XXL size might be too large for smaller vehicles
* Folding it back into the provided storage bag can be challenging
* Soft shell offers less physical protection than a hard box
* One zipper potentially failed after heavy use (based on reviews)

Deep Dive into Features and Benefits

After extensive use across multiple seasons and varied trips, I can genuinely speak to the performance of the Mockins XXL 50 Cu Ft Waterproof Rooftop Cargo Carrier Bag.

Unmatched Capacity and Versatility (50 Cu Ft Size)

The first thing you notice about this rooftop carrier is its sheer scale. At 85″x50″x20″, the 50 cubic feet of capacity is truly expansive. This isn’t just a small boost in space; it’s enough room to pack luggage for a large family for a week, or haul bulky camping gear like tents, sleeping bags, chairs, and more, all at once. Over the years, this capacity has been a game-changer. It means I no longer have to choose between bringing essential items or leaving passengers crammed inside with bags piled around them. The benefit is significant: more comfortable trips for everyone inside the vehicle, and the freedom to bring everything we need for the destination. I’ve used it for everything from cross-country moves hauling boxes to weekend camping trips with all the comforts of home. It’s far exceeded my previous expectations of what a car roof bag could hold.

Triple-Protection Waterproofing System

One of the most critical aspects of any rooftop carrier, especially a soft shell, is its ability to keep your belongings dry. The Mockins cargo bag boasts a “triple-protection” system, and based on my experience, it lives up to the claim in most conditions. The primary material is a heavy-duty, abrasion-resistant vinyl. This material itself is water-resistant. Layered on top of this are double-sealed waterproof zippers. These aren’t just standard zippers; they are designed to prevent water ingress. Furthermore, the zippers are protected by a substantial 2-inch flap, which is then secured tightly with wide 5.5-inch Velcro strips. The combination of the vinyl, sealed zippers, and the large Velcro flap creates a highly effective barrier against rain, snow, and road spray. I’ve driven through torrential downpours and icy conditions with this bag, and everything inside has remained completely dry. The reinforced welded seams also contribute to this, preventing water from seeping through stitching points often vulnerable in lesser bags. This level of waterproofing provides immense peace of mind when traveling in unpredictable weather, knowing your clothes, electronics, or other gear are safe.

Versatile Mounting and Security (Fits With or Without Racks)

Perhaps one of the most appealing features of the Mockins rooftop cargo carrier is its adaptability. Whether your vehicle has factory-installed crossbars, side rails, an aftermarket roof rack, or even a completely bare roof, this bag comes with the necessary hardware to secure it safely. The bundle includes multiple sets of adjustable ratchet straps and durable buckle straps. These are robust and allow you to cinch the bag down securely, minimizing movement and wind flap. For vehicles without racks, the inclusion of 6 door hooks and 2 trunk hooks is ingenious. These allow you to route the straps through the door or trunk openings and hook them securely to the vehicle’s frame, providing anchor points where none exist on the roof. I’ve primarily used it on vehicles with crossbars, where the straps wrap around the bars, but I’ve tested the door hook system on a friend’s bare-roof sedan, and it held the bag firmly in place. The flexibility means you don’t need to invest in an expensive roof rack system just to use the bag. The included anti-slip gripper mat (82″x48″) is another thoughtful addition. Placed under the bag, it provides a non-slip surface, preventing the bag from shifting during transit and, crucially, protecting your car’s paintwork from scratches and scuffs. A combination lock is also part of the package, offering a basic layer of security for the zipper pulls, useful for deterring casual tampering during stops. This comprehensive set of mounting options and security features ensures that the bag stays put safely and securely, regardless of your vehicle’s setup.

The Complete Accessory Bundle

One of the standout aspects of the Mockins rooftop cargo carrier is that it truly arrives as a complete package. There’s no need to buy extra straps, hooks, or a protective mat separately. This bundle includes everything required for installation and use right out of the box. You get the massive 50 cu ft bag, three sets of ratchet straps for heavy-duty securing, three durable buckle straps for general cinching, six door hooks and two trunk hooks for rack-less mounting, the generous anti-slip mat, a combination lock, and a carry bag for storage. Having all these accessories included simplifies the setup process significantly. It means you spend less time figuring out compatible hardware and more time packing for your trip. The convenience of having multiple strap types and mounting options available allows you to choose the best method for your specific vehicle and load. While the carry bag is included, I’ve found, as have other users, that refolding the large bag precisely to fit back into the relatively compact storage bag can be quite challenging after it’s been used and unrolled. It’s not impossible, but it often requires more effort and time than you might expect, sometimes leading users to find alternative storage solutions like a larger tote or simply rolling it and securing it with a strap. This is a minor quibble but worth noting if compact storage is a primary concern.

Durability and Build Quality

Over the long term, the durability of a rooftop cargo bag is essential. The heavy-duty vinyl material used for the Mockins bag feels substantial and capable of withstanding the rigors of highway speeds, varying temperatures, and exposure to elements like road salt and UV rays. The reinforced welded seams, mentioned earlier for waterproofing, also contribute significantly to the bag’s structural integrity, preventing tears or blowouts under stress. The straps and hooks included are also made from strong materials designed to bear significant weight and tension. While the overall build quality is high and the bag has held up exceptionally well for me over multiple lengthy trips, it’s important to note that, like any soft-shell product subjected to extreme conditions and frequent use, wear and tear are possible. One user review mentioned a zipper failing after prolonged, heavy use on a very long journey. While this wasn’t my personal experience, it highlights that while the bag is built tough, mechanical components like zippers can be potential points of failure over extensive use cycles, particularly if overstuffed or stressed. However, the rest of the bag’s construction and the redundancy provided by multiple straps instill confidence in its long-term reliability.

Customer Care and Warranty

Mockins stands behind this car top carrier with a 10-year limited warranty, which is quite generous for this type of product. Knowing that the manufacturer is willing to offer such a long warranty provides a sense of security regarding the product’s quality and the company’s confidence in its durability. While I haven’t needed to utilize the warranty, the assurance that customer support is available for questions or concerns is a valuable benefit, especially when dealing with a product integral to safe travel.

What Users Are Saying

Looking online, the feedback from other users who have purchased this Mockins bag is largely positive and aligns with my own experience. Many reviewers rave about the ease of installation and the versatility provided by the included straps and hooks, noting that it worked well on different vehicles, including those without roof racks. The vast size is frequently praised, with users mentioning fitting luggage for entire families with room to spare. The durability and waterproofing also receive high marks, with multiple accounts of items remaining dry despite driving through heavy rain and snow during long journeys. Users appreciate the comprehensive kit, especially the anti-slip mat for protecting the roof. While one user did note a zipper issue after extensive use on a particularly long trip, the overall sentiment is that it’s a well-made, effective, and valuable storage solution.

Final Thoughts

If you’re someone who frequently finds themselves short on packing space for road trips, camping adventures, or moving, solving that problem is crucial to avoid cramped cars, discomfort, and the potential safety hazards of an overloaded vehicle. The Mockins XXL 50 Cu Ft Waterproof Rooftop Cargo Carrier Bag is a fantastic fit for addressing this challenge. Its enormous capacity means you won’t have to compromise on what you bring, the robust waterproofing protects your belongings from the elements, and the included comprehensive mounting kit makes it incredibly versatile for use on almost any vehicle.
