For our recent family trip to OBX, I purchased this bag to transport our clothing and supplies, as we had 3 adults, 1 child, and a dog in the car. Although I cannot vouch for its weatherproofing or waterproofing capabilities since we encountered no rain, I can attest to its incredible capacity to hold nearly EVERYTHING we brought, except for our cooler. In the past, we used a hard shell rooftop carrier, which had limited space and required us to pack the vehicle's interior, leading to an uncomfortable journey for everyone. Conversely, this bag's soft nature allows for greater storage and adaptability. We were truly astonished by its storage potential!!The straps held up perfectly during the 10-hour drive. There are 2 straps on each corner and 2 large straps across the center. We also brought a ratchet strap as a precaution, but it was unnecessary.NOTE: I positioned the bag directly behind our front cross rail and laid it over the rear cross rail. From the rear cross rail, there was about a foot of extra storage space in the bag, which I filled up. By placing the bag "over" the rear rail (instead of removing it), everything became more stable and secure.Even at highway speeds, this bag performed FLAWLESSLY!!

The cargo bag was incredibly useful during our trip from San Antonio, Texas, to Centralia, Illinois. Despite encountering rain for about 5 hours, everything inside remained dry, and the bag stayed securely in place. My husband's expertise in anchoring and tying down items made the installation process a breeze for him. However, I wouldn't have been able to replicate his technique due to my lack of experience with strapping. We used this on our Ford Escape, which allowed us to keep the entire trunk empty for our personal carry-on items. The cargo carrier bag accommodated a significant amount of our belongings. Even when we faced some snow along the way, the contents stayed completely dry. I wholeheartedly recommend this product.

The cargo topper accompanied us from New York to Montana, then through Canada, arriving in Anchorage, AK, without any problems. It withstood snow, rain, and freezing temperatures, showing no signs of wear or tear. We unloaded and reloaded the topper at each of the 8 hotels we stayed at during our journey. This purchase proved to be an excellent investment in transporting some of our belongings. I wholeheartedly endorse this cargo topper!

I was skeptical about purchasing this product. We had planned a 16-hour trip from Illinois to Florida, thinking there was a hitch to attach a trailer to my car. This carrier was spacious enough to accommodate 4 large suitcases and more. My primary worry was the possibility of rain. Sure enough, we encountered severe rainstorms. I was certain that upon arriving at the hotel, our belongings would be drenched. To my astonishment, not a single drop of water penetrated the carrier. My next concern was whether the straps would withstand speeds exceeding 80 miles per hour. I frequently checked to ensure the carrier remained secure on the car's roof. I feared that a strap might snap. However, it held strong from Florida back to Illinois, with no signs of strap damage. I was thrilled we made this purchase, as we had procrastinated until the last minute before realizing we couldn't use a trailer. This is undoubtedly a worthwhile investment.

Employed to bring my son's belongings home from college, this was simple to set up and remove. We covered 550 miles from Virginia to NY without any problems, even in inclement weather. It includes a customizable combination lock. It folded up effortlessly and fit back into its original storage bag. Cleans nicely and is a better choice than a cargo carrier if storage space is limited. We filled it with 6 sizable duffle bags packed with clothes, and it handled the load perfectly.

The fabric used in crafting this item is exceptionally sturdy and dense. It is by no means flimsy or thin. The zippers are equally robust. Simply orient the company logo towards the front of your vehicle, and you'll be set. It includes additional straps for use without roof bars or a rack. We plan to utilize this on my SUV for an upcoming road trip to Devil's Tower, Mt. Rushmore, and Deadwood in South Dakota. It even features a small lock that can be inserted into the holes where the two zippers meet. It's a combination lock, but no information is provided on the combination. However, you'll likely figure it out quickly - it's three of the same number. It took me about a minute to determine the combination and how it functioned. Ultimately, I decided the lock was better suited for our tent door zippers.

Purchased to utilize our Kia's 3rd row, this carried all necessities for a week-long beach trip 15 hours away with three children and two adults, even our large cargo wagon. After securing it tightly, there was no perceptible outside noise. Encountered some heavy summer rain while driving, yet the contents remained completely dry. Extremely satisfied with this acquisition, we'll definitely employ it on future journeys without hesitation.

The product endured constant highway speeds through several winter storms with strong winds, rain, and snow from the US west to east coast and back. The only downside is its rigidity, requiring arm strength to handle while standing on your vehicle in cold weather. I didn't utilize the provided hooks as I could attach it to a roof basket. If your basket is shorter than the bag, I suggest loading from the rear to the front and "folding" the excess space at the bag's front into itself, creating a flap, then securing it to whatever you're attaching the bag to on your vehicle. This will minimize additional creases that could increase wind noise. In a pinch, this is a highly cost-effective option for a last-minute road trip.

My spouse and I purchased a pair of these roof bags, and they're fantastic! We journeyed roughly 2800 miles through various weather conditions over 4 days, and all our belongings remained unscathed. We followed the packing instructions and encountered no issues. The bags were simple to secure to his roof rack and my Corolla's roof using the 4 tie-downs. The included locks were a great bonus. All in all, I believe it was an excellent investment.
