Best Waterproof Rooftop Cargo Bag (Review) 2023

Not being able to fit all of necessary belongings in your car for the trip can be really frustrating. However there are multiple ways to deal with such issue. Perhaps the best one is buying a waterproof rooftop cargo bag – they are spacious, convenient and less expensive than hard-shell rooftop cargo carriers. The most important factors when choosing the right rooftop bag for you are:

  • Durability – When you buy something you want it to be a long term investment. A bag that all of a sudden starts to develop tears and holes can be very dangerous and cause lot of headaches. Rooftop cargo bags aren’t as long lasting as hard-shell cargo carriers but some can last for a few years of frequent use.
  • Waterproofness – To protect your belongings from damage you don’t want to experience any leaks inside the bag. Some bags are water resistant enough to stay dry even during heavy rainstorms, others are only partially water-resistant and will allow some moisture or small amounts of water get inside. And then there are those who lack proper materials and features to keep water away or are of poor quality and will tear up letting water inside.
  • Storage capacity – Most of the rooftop cargo bags have storage capacity of 15 cubic feet which in most cases is enough. Even though 15 cubic foot might not sound like a lot you can actually store more inside than you intuitively expect. More spacious bags also tend to be more expensive and there’s no need to overspend unless you actually need extra space. But if you suspect it might not be enough then opting out for a larger bag is a wiser choice.
  • Installation – Some rooftop cargo bags are easier to install than others. Some might require a roof rack, others don’t.

#1 RoofPax Car Roof Bag

RoofPax car roof bag offers 19 cubic feet of storage capacity – more than most rooftop cargo bags but that’s not enough to make it the best among all.

RoofPax car roof bag made of military grade 1680-D PVC fabric with water repellent tarpaulin double coating that not only increases water resistance but also protects bag from UV rays. It does feel well made indeed – materials and thick and durable. It’s sturdy and leaves good first impressions.


RoofPax car roof bag is very water resistant. Inside manages to stay dry even during particularly heavy rainfalls.

Keep in mind that nothing is truly waterproof. If you submerged this bag under water for a year surely some water would get inside. And there are 1 in a 10,000 (or whatever the number is) bags with some kind of manufacturing defect.

Still, when it comes to protecting your belongings from getting wet or moist RoofPax is the best car roof bag you can buy.


RoofPax car roof bag has features like waterproof dual seam technology, heavy duty SBS zipper, 10 elastic velcro straps with NIFCO buckles and double strap covers with 8 Velcro stripes.

One particularly nice feature that most rooftop cargo bags don’t have is built-in mat that protects paint of your car’s roof from scratches and also provides extra grip to keep bag stay put.


RoofPax car roof bag can be installed whether you have roof rack or not. Unlike most cargo bags it uses door hooks which are simpler to install and apparently also a safer solution.

Noise and mileage

RoofPax car roof bag doesn’t cause much additional noise but will have some impact on your mileage. Expect to see decrease your MPG by couple digits. Compared to other bags it does seem to affect mileage and noise less than most.


RoofPax is the best affordable car roof bag you can buy in 2023!

ToolGuards roof bag is pretty good but it’s not quite perfect.

#4 P.I. AUTO STORE ROOFMASTER Rooftop Cargo Carrier Bag

P.I. AUTO STORE ROOFMASTER is one of the least expensive rooftop cargo carrier bags. It has 16 cubic feet of storage capacity – 1 more than average despite costing less than most.

#5 Rightline Gear 100S30 Sport 3 Car Top Carrier

Rightline Gear 100S30 Sport 3 Car Top Carrier is pretty large, its storing capacity is 18 cubic feet but it does come at a cost – it’s 2-3 times more expensive than most of the other rooftop storage bags. The carrier is made out of UV protected PVC Semi-Coated Mesh XT and Hydrotuff. It features Dual Seam Technology – materials are sewn together for strength and welded for waterproofness. Zipper is also urethane coated (ZipRight System).

In real world the bag works fine. It really is waterproof and stays completely dry during and after heavy rain. Rightline car top carrier seems to be sturdy and durable, however it’s no more durable than cheaper but higher rated storage bags. In hot temperatures (125+ Fahrenheit) the rubbery material starts to get soft but that didn’t seem to cause any issues.

Rightline Gear 100S30 Sport 3 is a good car top carrier and offers 3 more cubic feet of storage space than most other rooftop cargo bags.

#6 Whistler Waterproof Car Roof Cargo Bag

Whistler car roof cargo bag is made out of heavy duty canvas. The bag is well made and durable, it’s not as high quality as RoofBag’s bag but it’s still very good nonetheless. Whistler’s cargo bag works great and manages to keep its contents intact – inside of the bag stays completely dry in heavy rain. It deals with heavy wind just fine and stays in its place the whole time. The fuel economy obviously gets affected and the wind noise isn’t that bad (but there is some!).

Installation is very easy. Comes with non-slip anti-scratch pad and storage bag.

Overall Whistler’s car roof cargo bag is durable and works just fine. It isn’t the very best one but it’s good enough.

#7 Rabbitgoo Car Rooftop Cargo Carrier Bag

Rabbitgoo rooftop cargo bag is very easy to install on the roof of a car. The material it’s made of is thick and sturdy, the bag itself is made from three layers for protection against sun, rain, wind, and grit. It’s durable and holds up well in windy and rainy conditions. It really is waterproof and keeps contents of the bag completely dry. It folds to a very compact size for convenient storing. Rabbitgoo rooftop cargo bag does make some wind noise but not too much where it becomes annoying.

Overall this is a decent rooftop cargo bag. It’s sturdy and well made, but it makes some wind noise and for the price doesn’t offer best value for money.


  • Weight: 6.55 pounds
  • Dimensions: 44 inches x 34 inches x 17 inches

The bag seems to be durable as I didn’t notice any wear after some use. Straps work great and the bag stays securely in its place. The bag does cause some road noise though.

Overall Vault Cargo Management rooftop storage bag seems to be durable and works just fine. However higher rated bags at similar pricing are just a bit better made and use better materials.


  • Weight: 6.3 pounds
  • Dimensions: 13.5 x 12.2 x 5.9 inches
  • Storage Volume: 15 cubic feet
  • Material: Heavy duty canvas

#9 AUPERTO Cargo Bag

AUPERTO rooftop cargo bag is made out of thick rubbery material, seams are well-sewn. It seems to be rather durable but some of the other bags feel sturdier. Inside of the bag stays 100% dry in thunderstorms and the bag stays safely in its place.

Overall this is a decent rooftop cargo bag. It could be a bit better made but it’s still a great value for money since it’s slightly cheaper than most other rooftop cargo bags.

#10 STDY 20 Cubic Feet Rooftop Cargo Top Carrier Bag

STDY 20 cubic feet rooftop cargo bag is made out of 600-Denier Polyester Material that has been high-frequency pressed into dense and compact surface. The fabric is good quality and bag is well made. It barely makes any wind noise and stays in its place – I never had to tighten the straps. After some use there was some fraying so it’s not the most durable rooftop bag but overall it held up well. It’s definitely waterproof and keeps any water or moisture away from bag’s contents. Survives heat and cold fine.

At 20 cubic feet this rooftop cargo bag has the biggest storage capacity out of all the bags I tried. It’s not as high quality or durable as the best ones, but overall it’s still well made so if you need extra storage space this one will be good enough.

#11 BougeRV Roof Top Cargo Bag

BougeRV roof top cargo bag is made out of 1000D PVC – a thick waterproof flexible material. It seems to be pretty durable however I only got to test this bag for less than 1000 miles. During this time I did experience some rain and the inside of the bag stayed dry. I must warn you that some of the customers that have bought this roof top cargo bag have complained about some light leaks, however I did not experience any. The cargo bag stays safely in place, it doesn’t move or slide. It’s also pretty quiet and doesn’t cause much noise.

Overall BougeRV roof top cargo bag seems to be working just fine, but some of the consumers reporting small leaks is a bit worrying.

  • Storage Volume: 15 cubic feet

#12 AmazonBasics Rooftop Cargo Carrier Bag

AmazonBasics rooftop cargo carrier bag is made out of thick vinyl, however the bottom layer is a bit thin and there could be more padding. The straps are nice and wide, easy to use and keeps the bag in its place. The bag overall is well made, it’s not super sturdy but it seems like it’s strong enough to last a long time – more than AmazonBasics one-year limited warranty.

The AmazonBasics rooftop cargo bag isn’t waterproof but it’s very water resistant. There are no leaks but the bag is prone to let in moisture inside the bag.

Overall AmazonBasics rooftop cargo bag is well made and works pretty good as well. It’s far from the best, but because it’s inexpensive it offers a great value for money.


  • Material: Vinyl
  • Weight: 6.2 pounds
  • Dimensions: 43.5 x 16.8 x 33.5 inches
  • Storage Volume: 15 cubic feet
  • AmazonBasics one-year limited warranty

#13 SHIELD JACKET Waterproof Roof Top Cargo Luggage Travel Bag

SHIELD JACKET waterproof roof top cargo bag has double-wall vinyl construction and 2 compression straps. The construction doesn’t seem to be very durable, but it isn’t fragile either. After 2000 miles of use the bag showed no signs of wear so this feeling of lack in durability might be false. It worked well in wind, snow and rain. SHIELD JACKET roof top cargo bag proved to be waterproof as there were no leaks or moisture in the bag at any point of my use. Straps well and stays in the place without any moving. A nice feature this rooftop cargo bag has is 2 compression straps which help to keep your baggage tightly and securely stored.

Overall it works ok although it doesn’t feel as well made as some of the other rooftop bags.


  • Weight: 7.15 pounds
  • Dimensions: 43”x34”x17”
  • Storage Volume: 15 cubic feet
  • double-wall vinyl construction

#14 Leader Accessories Rooftop Cargo Bag

Leader Accessories rooftop cargo bag build quality is decent but not great, however the straps are flimsy and weak. The bag is waterproof – I did not experience leaks or moisture in the bag. The bag is soft type.

Overall the build quality could be better. You can get better bags for slightly lower pricing so I won’t suggest you this one.


  • Storage Volume: 15 cubic feet
  • Dimensions: 44” x 34” x 17”
  • Weight: 8.55 pounds

#15 Oanon Car Top Carrier

Oanon car top carrier has a massive 20 cubic feet storage capacity. The bag is coated with high quality polyvinyl chloride to make it waterproof. During my use the inside of the bag stayed 100% dry during heavy rain. The bag held up well in snowy conditions as well. However during my research I came across many complaints about this product not being waterproof. There are many consumers complaining about massive leaks.

Although during my use the bag worked perfectly the many complaints I found about this product is worrisome. Because of this I would suggest you to get a bag that I and large majority of other consumers had a positive experience with.


  • Storage Volume: 20 cubic feet
  • Weight: 8 pounds
  • Package Includes:
    • 1 x Roof Bag (51” x 40” x 17”)
    • 1 x Storage bag (15.7” x 12” x 5”)
    • 2 x Long Straps (3M)
    • 6 x Tough Wide Straps

#16 COOCHEER Car Roof Carrier

COOCHEER car roof carrier is made from rubber laminated nylon. The bag itself seems to be well made but straps seem to be fragile. They also don’t do that good of a job of holding bag securely and preventing it from moving. You can fix this by getting ratchet straps or with different solution but I like my products to be well engineered from factory. COOCHEER car roof carrier bag is easy to install, load and unload. It’s waterproof and I did not experience any leaks.

COOCHEER car roof carrier is mediocre quality product. You can get better products for lower pricing so I can’t suggest this car roof carrier.


  • Rubber laminated nylon
  • Storage Volume: 20 cubic feet
  • Dimensions: 43.3”x31.5”x17.7”
  • Package includes:
    • 1 x COOCHEER car roof carrier
    • 4 x Strong, wide straps
    • 1 x Storage bag (15.7” x 11.8” x 5.1”)

#17 Keeper 07203-1 Waterproof Roof Top Cargo Bag

Keeper 07203-1 roof top cargo bag is made out of rubber laminated nylon. It’s quite water resistant but not 100% waterproof, there is a chance of a leak or moisture. Another problem with this roof top cargo bag is that it isn’t durable – just after 2000 miles of use it already starts to show some serious wear. At least it’s quiet and doesn’t make much wind noise.

Keeper 07203-1 isn’t 100% waterproof and it’s far from durable. Because of this I suggest avoiding it and getting another roof top cargo bag instead.


  • Material: Rubber laminated nylon
  • Weight: 5.25 pounds
  • Dimensions: 4 inches x 34 inches x 17 inches
  • Storage Volume: 15 cubic feet
