Strap and buckle

This compact cargo bag lets you transport up to 12 cu ft of gear on your vehicle's cargo carrier. It's perfect for small luggage, sports equipment, tents, and sleeping bags. The poly canvas tarpaulin construction, welded seams, and covered zippers help to keep your gear clean and dry. The bag attaches to your carrier with 6 integrated straps, and it folds up for compact storage.

Waterproof Tarpaulin Construction

The cargo bag is constructed of 500-denier tarpaulin so it's hard to cut or tear, and it protects your cargo from dirt, dust, and road grime. The seams are also welded to create a watertight seal.

Large, Zippered Opening

Opened bagZipper close-up

A large opening on top of the bag makes it easy to load and unload your cargo. Two zippers wrap around 3 sides of the bag so you can fully open the top, and because it opens from the rear, the zippers won't open due to oncoming wind. The zippers are covered with a flap that secures with hook-and-loop fasteners. This flap provides extra moisture protection for your cargo. You can add a small padlock (sold separately) to the zippers to secure your cargo.

Heavy-Duty Tie-Down Straps

Strap and buckle

The bag has 6 tie-down straps with Duraflex snap buckles that secure it to your cargo carrier. Simply feed the straps through the rails or bars of your cargo carrier, connect the buckles, and pull the straps tight. You can use the included hook-and-loop retainers to keep the excess strap length out of the way. The extra-strong straps have a UV50+ protection rating so they won't break down even after extended exposure to the sun.

Convenient Storage

Storage bag next to cargo bag

This bag is flexible so you can fold it up and store it on a shelf in your garage or basement when you're not using it. It includes a storage bag to protect the bag and keep it clean and dry.

It is definitely NOT waterproof. Our camping gear got soaked on our last trip and had to skip our last night of camping.


We run a private SUV service in Colorado and just purchased our third Rhino Rack RRLB 350. This rooftop bag offers 12 cubic feet of capacity and has been used in several wet weather conditions without a single issue. This bag has kept our clients personal belongings dry in every storm, period.

This 350 Model will easily hold two LARGE suitcases and one medium suitcase. If you need to hold more than that, there are two other models that offer more capacity than the 350.


After a year of use, the cargo bag has served us well. We pack relatively light, but often bulky, camping stuff in it for our overlanding adventures. It represents a not-expensive choice compared to strapping down various not-cheap boxes to your roof rack. Recommend.


Excellent product, completely waterproof. Bag was easy to install with adjustable straps everywhere. Bag compresses nicely after your items are inside. Very happy with the product!


We got this cargo bag to give us more space in the back of our Jeep for extended trips. It's made really well with thick materials and hefty zippers. It holds a good amount of gear thus freeing up space as we intended. Easy to strap onto our roof rack. Like the flap that velcros down over the zipper to keep dust and water out. Very happy with it!


Tim @ etrailers was great... I called there & asked questions about this luggage bag and he answered all questions & was obviously knowledgeable. Also, told him we were going on vacation soon & he made sure that the bag arrived on time. We received it just a few days later.. I can see why one of my clients recommended going through ETrailer.. great job Tim!!!!


Like the bag, used 6-8 times with no problems. Works well with soft things, backpacks, pads, tents, etc. but wish I had got the bigger one. Only drawback is that it is fairly tough to zipper up when full, especially hanging off the top of my truck. I would purchase this product, well made, held up great so far.


I have yet to utilize this cargo bag so i will update after it sees some action. As for etrailer they are reliable and responsive and definitely recommend buying from them in the future. Reasonable prices compared to many other online retailers.


Initial impressions are that this is very well made as long as it holds up to weather. I'm sure it will do all I expect of it. The zippers which would be the weak point are covered in flaps so they have little direct exposure to the elements. I have no reason to think this cargo bag will not do as expected.

See what our Experts say about this Rhino Rack Car Roof Bag

  • What is the Length of the Side Straps on the Rhino-Rack Rooftop Cargo Bag?
    I had a teammate measure the side straps of the Rhino-Rack Rooftop Cargo Bag # RRLB350, and the straps measure 26 inches. Given that the width of the bag is 37-1/2 inches, that leaves a combined length of 63.5 inches. This measurement will give you plenty of side strap length to attach the straps to the outer frame (if your bag is centered on the platform).

  • Recommended Low Profile Rooftop Cargo Bag
    Since you are seeking low profile, there isn't any other manufacturer that compares to Rhino-Rack for that lower profile design. Others are just as good in other ways, but they are far taller ranging between 15 and 19 inches. I've linked all the options if you want to check them out. You will want to choose between the Rhino-Rack Rooftop Cargo Bag - Waterproof - 17.5 cu ft - 59" x 43" x 11-1/2" # RRLB500 and the smaller Rhino-Rack Rooftop Cargo Bag - Waterproof - 8.5 cu ft - 43" x 31-1/2"...

  • Recommended Rooftop Cargo Bag For The Rhino-Rack Roof Mounted Steel Cargo Basket
    For the Rhino-Rack Roof Mounted Steel Cargo Basket # RMCB, I recommend using the: -Rhino-Rack Rooftop Cargo Bag # RRLB350. The # RRLB500 is too wide and too long to fit on the Rhino-Rack Roof Mounted Steel Cargo Basket # RMCB. Additionally, the Rhino-Rack Rooftop Cargo Bag # RRLB350 has a storage capacity of 350 liters or 12 cubic feet, and measures 47" long, 37-1/2" wide, and is 11-1/2" tall.

  • Roof Cargo Basket and Bag Recommendation for Infiniti QX56
    I am not sure what year Infinti QX56 you have so it's hard for me to check with manufacturers to verify fits, but the Rhino Rack basket part # RMCB02 that you referenced is a great option that fits most racks. As long as your bars are less than 3-1/2 inches wide and 1-1/4 inches tall and between 25-1/2 and 43 inches apart this basket will work well. It has dimensions of 57" long x 42-13/16" wide x 5-7/8" tall. Then for a bag the Rhino Rack Cargo Bag part # RRLB350 would be a great option....

  • Will The Rhino-Rack Cargo Bag RRLB350 Fit Thule Canyon XT Cargo Basket TH859XT?
    Yes, the Rhino-Rack Rooftop Cargo Bag - Waterproof - 12 cu ft - 47" x 37-1/2" x 11-1/2" # RRLB350 would be a great fit for the Thule Canyon XT Roof Cargo Basket - Steel - 49" x 40" x 6" - 150 lbs # TH859XT. The Rhino-Rack Bag has slightly smaller dimensions than the Thule Cargo Basket so they would work well together. This bag is waterproof like you wanted and includes 6 integrated tie-down straps to be secured to the cargo basket; this is the cargo bag I recommend for your application.

    For your 58" long x 47" wide Rhino-Rack Pioneer Platform Rack # RR42115BF with the Full Rail Kit # RR43201B, the best option is going to be the 47" long x 37-1/2" wide Rhino-Rack bag: - Rhino-Rack Rooftop Cargo Bag # RRLB350 This will give you the best fit inside the rail kit of your Pioneer Platform. The 59" long x 43" wide Rhino-Rack Rooftop Cargo Bag # RRLB500 can work as well, but depending on the cargo you are carrying, if it is too long at the bottom and takes up the full length...

  • Durability Of SofTop Roof Top Cargo Carrier
    The Advantage SportsRack SofTop Rooftop Cargo Bag # HE3021 bag can be mounted and secured to the top of your horse trailer. That being said the bag is not waterproof per 0:40 of the video and water can get through the zipper potentially so these factors could cause the bag to not be ideal for all the time, permanent use. The bag may be more ideally used and then stowed away when not in use as it could wear down in the elements. An upgraded bag like the Rhino-Rack Rooftop Cargo Bag #...

  • Roof Bag Recommendation for 2009 Buick Enclave Without Roof Rack Installed
    The Rhino-Rack Rooftop Cargo Bag # RRLB350 is designed to secure around the rails of a roof cargo basket so since your 2009 Buick Enclave has flush mounted rails that the basket can't secure to you'll want to use a different bag like the Rightline Gear Sport 3 Rooftop Cargo Bag # RL100S30 which has the same general dimensions but comes with clips on the straps so that you can secure it to the door jamb area on your vehicle. I also recommend making sure the roof of your Enclave is clean...

  • Recommended Roof Top Cargo Bag On A 2011 Honda CR-V With A Crossbar Spread Of 25
    I do have a few options for you to consider on your 2011 Honda CRV. However, most cargo bags will not sit atop the crossbars but rather use them as an extra mounting point. Therefore, a rooftop cargo bag will sit directly on the vehicle's roof which will not allow for the use of your sunroof while installed or allow for much weight to be carrier. For a rooftop cargo bag, I recommend the Rightline Gear Sport 3 XL Rooftop Cargo Bag part # RL100S30. The Rightline Gear Sport will hold up...

  • How to Secure Cargo to Inno Shaper 100 Roof Cargo Basket
    This is a little tricky as the Inno Shaper 100 Roof Cargo Basket # INXA569 doesn't have a specific cargo net made for it. The best recommendation I have in the way of a net is the Reese Stretchable Cargo Net # H9500100 and just making sure you wrap the hooks around the bars and secure them back directly to the cargo net. For this application I recommend using something like the etrailer Cam Buckle Cinch Straps # E98876-2 instead because you can wrap them around the bars and pull them as...

  • Can I Install the Rhino-Rack Rooftop Cargo Bag on Roof Racks?
    For these items, the intent is for them to buckle inside a cargo basket. A roof basket like the Rola Mounted Basket, part # 59504 would let you use it. The Rhino Rack Rooftop Carrier Bag, part # RRLB350, only has straps long enough to connect to a roof basket, not all the way around and through the inside of the vehicle or even around just the factory roof rails. A better solution for you would be a bag that outright mounts to your existing roof rack, such as the Rightline Gear Ace Jr....

  • Cargo Bag and Cargo Net Recommendations for Thule Trail XT Roof Cargo Basket
    The Thule Trail XT Roof Cargo Basket # TH865XT has external dimensions of 63" long x 39-1/2" wide x 7" tall and a cargo net that will fit and work great is the Thule Cargo Net with Storage Bag # TH692 which measures 40" x 36" but will stretch out to cover the Trail XT cargo basket. In regards to the Curt Cargo Bag for Roof Basket # C18221, it is 59" long x 34" wide so it wouldn't be the best fit for the Trail XT which has inside dimensions of 54-1/4" long x 37" wide.

  • Recommended Roof Rack for Basket and Bag on 2017 Honda Pilot with Bare Roof
    Any of the aftermarket roof racks we offer that are designed to fit your 2017 Honda Pilot can be pretty easily removed if desired, but all still have the capacity to safely support a carrier and bag during travel. In fact with most roof rack systems (even "temporary" systems) you will really be limited by the capacity of the Pilot's roof itself, as the roof racks are generally rated higher. I took a look at the online version of the owner's manual for your Pilot and it does list a 165...

  • Rhino-Rack Roof Rack and Cargo Basket for 2017 Jeep Renegade
    Rhino-Rack roof racks and cargo baskets offer excellent quality at great prices and for your 2017 Jeep Renegade we have roof rack options for Renegades with a bare roof and models with a roof that has raised front-to-back side rails.
