We bought this bag for travel in Costa Rica. Before we flew down, we checked it for defects and sample packed it on the ground with luggage, but how would it fit and perform on an unspecified rental? Vamos Rent-A-Car provided our vehicle with roof rails as booked, and their mechanic was onsite and adjusted the rails to the bag length. Sweet!I absolutely ignored one apparently incorrect installation instruction that came with the bag and is also in MCBD’s video on Amazon. Please listen. The directions and video indicate to install the bag with the MCBD logo facing the front of the vehicle. Bad idea. My bag, and the one they install in the video, have the logo printed below the zipper. This is the BACK panel. On a rooftop bag with 3 zippered sides, for the best wind and water shielding performance, the non-zippered side should always face the FRONT. I am reaching out to MCBD about this apparent error, I will update this if they give me any detail.Loading and securing the 21 cubic foot bag was easier with two people. It held our six hard suitcases - four medium and two smaller carry-ons. I brought ratchet straps and zip ties as a precaution, but didn’t need them. TSA had no issues with the bag or ratchet straps in our carry-on luggage.The bag was in use for about seven hours total over three days, with the bag being removed and installed between uses. Our drives included 2-3 hours of light rain. Despite bumpy roads with potholes and speed bumps, the bag stayed secure, and with the non-zippered side facing the front, everything remained dry. I periodically checked the straps, and they held firm.Another key to having no bag issues was loading the roof bag with no sharp or pointy edges or objects against the bag or it’s zippers. We made sure to place the suitcases so their wheels faced into the center of the bag, and packed so the zippers did not have to be strained to close, and had even tension on them.

This works awesome. I do not have a roof rack on my car. I used it for our trip across the country. It held way more than expected. Very sturdy and waterproof. Can't wait to use it again.

Upon writing this review, I’ve used this once on a camping trip. The cargo bag worked well to transport a handful of extra bags atop my car. It withstood my 65-70mph highway speeds and was pretty user friendly to operate. It did not rain much at all so I can not speak to the waterproof quality yet.However, a disappointment I have is that TWO Velcro pieces were kit made properly (see photos). The item still worked ok, but I’ll be seeking a replacement for a 100% inspected and properly produced unit.

I want to rave about this cargo bag. I bought it for a week long family trip consisting of around 3k miles of travel across a large section of the US. This bag was one of three items purchased to haul luggage of 2 adults and 4 teenagers on the roof of a 2021 Tahoe. The other items purchased were a set of roof rail bars which would support a large cargo basket, which this cargo bag would rest upon. The combination worked better than i expected. As far as the cargo bag is concerned, it appears to be well made. Materials heavier than i anticipated. Heavy duty zipper that goes around 3 sides. The zipper is covered by a large 'flap' that velcros closed over the zipper, making it nearly impossible for water to penetrate. The interior area is massive. 21cuft, i believe. This bag stored all of the luggage for six people with the exception of one carry-on size suitcase. In all, i believe there were two large suitcases, 3 medium suitcases, 3 carry-on size suitcases, and two gym bags. This was only achieved after a couple days of travel and figuring out the most efficient positioning of the items, but once perfected, this bag then held bags and bags of stuff purchased while on the trip in addition to the luggage mentioned earlier with no problem at all.On to weather. It was raining as we set out on day one. Before the end of the first 800 mile day, we had driven through a severe storm complete with driving rain, 50+ mph winds, and tornado warnings. This was a bonafide hyphoon! We were in the think of it for over an hour and in the rain all day. When we arrived at our hotel, i was amazed to find that there wasn't one drop of water in the cargo bag! Dry as a bone. This weather was repeated two more times before the trip was over. We never found any water at all inside this bag. It is literally impenetrable. Once we returned home, i hosed all the bugs and what not off the front of the bag, folded it up, and put it back into its handy nylon storage bag. One hint if using this bag, it has a zipper around 3 sides. The side that does not unzip is the FRONT. Face the bag with the solid side of the bag facing the front. When closing the bag, be sure the zippers meet at the rear of the bag. Be sure to position the 'flap' over the zipper all the way around and secure with the velcro. If these steps are adhered to, im sure this bag will perform equally well as mine does. If looking for a large capacity, truly weather-proof cargo bag, you can stop searching and purchase this one. I cannot imagine there being a higher quality cargo bag in existence and this price can't be beat.

This was awesome. Used it for a nearly cross country move. Was easy to use, pretty self explanatory, waterproof, bug proof, sturdy materials, has its own carry case, can fit a looooot.Make sure you don't put anything angular against the zipper seam, make sure the rectangle of the bottom is lined up on your car roof, pack the load evenly across (then build it upwards), when strapping down strap all sides loosely, then snugly, then tightly, keep duct tape on hand in case if a zipper pop (it shouldn't but at the least you are prepared).

2019 VW TiguanFit great on the roof. Zipper and the tie-downs are super strong and it was super quiet. Drove 3 hours in the hot sun 107 degrees for 3 hours at 70mph and no problems. The amount of space is fantastic and fit completely secure on my roof. The bag is pliable and so much better than a hard shell. You can fit tons of stuff in it. 4 camping chairs, 2 tents, a pop-up canopy, 6 vacuum bags of blankets, pillows and clothes, charcoal and cooking equipment. Fast shipping!

**Edit**We just returned from a road trip to Florida and back and this bad boy outdid itself, once again! We drove over 6000 kms with it on the minivan this time around, and it held up beautifully! Once again, we drove through freezing cold weather, rain, intense heat, and back to snow, high winds, and freezing temps without any issues whatsoever.In total, this carrier has travelled over 10,000 kms and is still going strong. This is the best $150-$200 we have ever spent.******We travelled over 4000 kms with this cargo carrier on the top of our minivan, and it held up 100%! We are super impressed!We left northern Ontario, Canada and drove through rain, snow, freezing rain, sleet, hail, incredible high winds, to finally arrive to sunshine and hot weather in South Carolina. We literally encountered every type of precipitation you can encounter, and everything stayed dry, nothing broke, the straps held everything perfectly. Where safely possible, we drove anywhere from 100km/hr up to 130km/hr at times, for four full 10-12 hr days straight, and we didn’t worry about the cargo carrier shifting at all. We managed to fit 3 large hardcover suitcases plus small backpacks, 3 boogie boards and a small camping chair in it.We are extremely satisfied with how well everything worked out given the low cost of the carrier compared to others.Slow clap to the manufacturer!

Hice un viaje de sonora a México y la vdd es que funcionó excelente , le caben bastantes cosas y es muy resistente, gracias a los broches que tiene se amarra muy bien al carro y las cejas que tiene para cubrir los cierres 10/10

Excelente producto para viajar tranquilo, facil de instalar, muy seguro y 100% impermeable, solo me gustaría que la alfombrilla antideslizante fuera un poco mas grande para poder proteger un poco mas el vehículo.

I ordered this semisoft / tarp material carrier for my 2011 SiennaSize -- knowing the cross car (rail to rail) was smaller than the width of this unit. I squeezed its deformable base (and all bags within the rails) and then expanded by putting 4" pvc pipes along the Drv/Pass sides to give side wall rigidity/prevent flapping (the height of my bags didn't take up all of the volume). I also put smaller bags at front in order to crush down more and have a wedge/ramp shape to reduce drag/flapping.Ease of Use-- takes a good 20 mins to pull zippers/straps tight and tie loose ends.I'm 6ft tall and could manage pulling / manipulating the flap lid to open/close over my luggage/bags from my sliding doors and rear bumper. If you're not as tall/less reach, you may need to consider the plastic foot step you can buy separately that attaches to the inner door loop.To pull the zipper closed, you really need to fight to keep the lid/flap from bending, so as to keep it parallel to the bottom half (more rigid). Once the zippers are pulled to the rear of vehicle, the pull down straps eat up the slack in the fore/after and cross car directions adequately (make sure to pull buckles to tightest positions)PROS -- having 6 buckles on 3 straps equally spread out and engaged with OEM roof rack felt sturdy and strong. Assuming a 5g load, 100 lbs max carrier means a 500 lbs force3 straps => 167 lbs each (fabric was thick/wide enough like camping backpacks)6 buckles=> 83 lbs each (plastic felt strong like on camping backpacks)At each strap the tarp fabric is reinforced and will likely be your eventual point of fatigue, failure (cracking/tearing) given the material type. Especially if you allow the material to violently flap with wind resistance. Product longevity will likely depend on excessive tension (or loose flapping) causing material wear/tearing and creasing of tarp material while packed in longterm storage.Bang for buck -- I had to transport my family's vases/paintings to NYC on an 8hr road trip. Unfortunately with kids, there was no interior room left to pack weekend clothes for everyone. Having this temporary carrier allowed me to keep my valuables in the car and bags of clothing outside. After delivery/weekend, our return trip had the carrier easily folded/stowed inside along with our bags of clothing. Saved me from needing two cars or renting a UHaul trailer. For the price, it was a welcomed increase in (weatherproof) vehicle storage (no additional $400tow hitch/$200basket, no roof cross bars for a $600 roof coffin, etc).CONS -- antislip mat was a little small for it's purpose. If you do not center it properly (and pull straps tight) the wind resistance will slide the whole carrier rearward. **As stated by others, adding your own frictional pad to add compression/prevent paint damage would help (similar spongy perforated rubber) increase vehicle to carrier grip.Conclusion -- price is very attractive for less frequently used carrier that may be easily folded/stowed after use (especially for underground parking/garages).

Loved this product. Works as expected. Only issue was a clip broke when tighten it down on the roof. Maybe add one or two extra clips with bag when purchased. Makes it a hassle when on the road and clip breaks and you can not tighten load down.
