Waterproof Storage Bag

Curt Hitch Mounted Bag

This waterproof bag fits in your vehicle's hitch-mounted cargo carrier and holds your gear, leaving more passenger room and trunk space. It is made of a heavy-duty material with welded seams and zipper flaps to keep your cargo dry. It opens on the front and side for easy loading with zipper pulls that can accommodate a padlock for added security.

Curt Waterproof Bag

The Curt cargo bag is constructed of a thick, UV-resistant vinyl that is designed to keep your gear clean and dry. Welded seams keep water from seeping into the bag.

Curt Zipper Flap

As an additional measure of protection for your gear, a vinyl flap covers the zipper and secures with hook-and-loop fasteners (similar to Velcro) to keep moisture out. When rain or snow hits, you can continue on your journey, knowing your cargo is safe and dry.

Simple Mounting on Hitch Cargo Carrier

Position the bag in your basket and load the bag with cargo. Then zip up the bag and secure the zipper flap.

Curt Bag Integrated Straps

Adjust the integrated polypropylene straps on the bag to the length needed. Then wrap each strap around the bars of the cargo carrier so that the bag is secured at 6 points. Tighten the straps with the sturdy plastic buckles.

Curt Foldable Bag

When you are not using the bag, just remove it from your roof and fold it up until your next trip.

Lockable Zippers Secure Gear

The zipper pulls have holes through which you can insert a padlock (sold separately) to guard against theft.

56x18x21. Store gear on your hitch-mounted cargo carrier with this waterproof cargo bag. Heavy-duty vinyl fabric, welded seams, and a zipper flap keep gear clean and dry. Durable straps secure to the carrier and tighten at 6 points for a snug fit.


This bag held more than I expected. After packing, there was even extra room. It kept everything dry during a rain storm, plus was easy to access during the trip. Highly recommend it. Sorry I forgot to take a picture when it was all strapped down.

Used the bag to take things back and forth to Florida twice. Everything stayed dry in rain, snow, and slushy ice.

Extremely well made product. Haven’t used it in the rain yet but it looks like it will handle it. Top customer service and very fast delivery!


Attached are photos of my new trailer and cargo bag. I LOVE them. Used the trailer for tailgating at the Jacksonville Jaguars wildcard playoff this past weekend. I could not have asked for better products! No problems whatsoever. Thank you!!!


Fantastic. Great solution for luggage with this waterproof carrier.


Good quality appears to be durable and a lot of space. Will be using on a road trip next month so I will know more upon return.


First, a big shout out to Shawn B and others, for expediting my order, so that I could have my equipment in time for a Girl Scout troop camping trip.

This bag is a perfect complementary piece to the Curt 20x60 hitch cargo carrier. It eliminates all hassles and need to tie down equipment that you plan to carry in the cargo carrier. You don't have to stress about any cargo flying away, as you're driving at highway speeds. I have only used it on one trip, in fair weather. But the construction seems heavy duty, and it looks like it would hold up well in rainy weather.

For my camping trip, I used it to hold the following equipment:
1.) 10'x14' 10 person tent
2.) 8'x10' 5 person tent
3.) 9'x10' 6 person tent
4.) 4 sleeping bags

Cargo such as sleeping bags is ideal to place in this bag, since they are bulky, yet relatively lightweight and quite compressible. With this cargo the bag was fully loaded. However, I could use the built-in straps to compress the bag enough so that there was enough clearance to open the tailgate on my 2015 Honda Odyssey.

Overall, it was a perfect complement to my cargo carrier and served my needs perfectly. (I'll try to post pictures later on. I have a second camping trip coming up in October)


Easy to use and roomy. Sturdy and waterproof (real-time tested!) construction. Fit well in our cargo frame and served its purpose for our trip.


The carrier performed exactly as expected & described a very well-built item. A local repair shop installed the mount, assembly of the carrier took less than twenty minutes. The carrier bag that was designed for the carrier kept our cargo clean, dry, and snug. Excellent product for a reasonable price -strongly recommend!


This is well made and waterproofing works. Drove all the way across Texas through a nasty winter storm and everything stayed dry.


Took on a family trip I have a Hyundai Santa Fe and yes it's fits all 7 of us but as for anything else no way. I also purchased the folding cargo hitch carrier. These two worked very well together bag fit perfectly and was secure from Vegas to Cali ... Also purchased top bag for roof and packed just incase of more needed space and pad that goes under for no scratches..


Very pleased with the cargo bag. Thick material, waterproof, fits the cargo carrier well, ties down easy and loads of room inside.


was looking for for a HITCH, CARRIER, AND BAG. Had no idea what to get but i came across etrailer and cured my problem. The bag works great. best service and people. Thank You


We are really happy with this product. It did its job. Bought the Curt Aluminum cargo tray (another curt product, C18100) and this bag. The bag is well constructed. We recently took it on a 1600+ mile trip...over 24 hours of total driving time, in sun, wind and rain. Everything inside the bag was in the same condition we loaded it. Recommended.


Used this on our trip from NY to FL. It rained most of the ride down. I few times even the big rigs were crawling. Everything inside was as dry as a bone. If your reading this just click add to cart. Oh and the straps lock it down great. But I used a cargo net over it. To keep any loose straps down.


Perfectly fits our Curt 20x60 cargo carrier. Love that it keeps our camping cargo secure and discreet. A must buy if you own a cargo carrier.


I hauled this cargo bag from Wisconsin to Arizona to Wisconsin. It rained steady from north of Carrizozo New Mexico to just west of Tucson Arizona. There was not one drop of moisture in the bag when I unpacked. This is a great product.


Item shipped and arrived on time. The next day we packed up our new cargo carrier and headed out to Florida. Extremely pleased with the durability and ease of use of this product. Hope to use it for many years.


Very nice cargo bag. Fits perfectly within Curt carrier. Appears to be all that was stated within description. Have not used on the road yet but I do not see any problems.


Great weather protection. Completely protects items packed inside. Carrier is build with sturdy material and performs as described.


The cargo bag arrived quickly and was easy to unpack and set up. I’m using it to transport clothes and household items when I move to my new home while my dogs ride in comfort inside the car. The cargo bag holds an impressive amount of items.


Kept everything dry, I just thought it would be a little quicker. Love etrailer tho, fast cheap shipping and replied very quick to my emails. Thanks again


Ordering process was easy. They had just what I needed. Item shipped the next day and was delivered quickly. Experience was 5-star all the way through. Thank you!


It's perfect storage for my trailer.


Amazing team! Arrived on time for our multi state road trip!!


Paula was amazing, I will continue to be a repeat customer! Thank you!

  • Is the Curt Cargo Bag # C18210 Rigid When Completely Empty
    The Curt Cargo Bag # C18210 referenced in your question will not have a rigid frame when it is completely empty. This cargo bag features heavy-duty vinyl fabric that is flexible so it will collapse a bit when empty. It has a storage capacity of 12.25 cubic feet and has overall dimensions of 56 inches long, 18 inches wide, and 21 inches tall. I have attached a short video demonstration on this product that you can also take a look at.

  • Fit And Compatibility Of Curt Cargo Bag # C18210
    The Curt Cargo Bag for Hitch Mounted Cargo Carrier - Waterproof - 12.25 Cu Ft # C18210 has dimensions of 56 inches long x 18 wide x 21 tall. With a carrier only 17 deep, this bag will technically be too wide, however it is a bag so it is flexible enough to fit. The only thing to note on making it fit is you may cause damage to the seams over time as this bag is recommended to be used on hitch-mounted cargo carriers at least 56" long x 22" wide. This is the closest fit to the dimensions...

  • Recommended Cargo Bag to Use with Curt Cargo Carrier # C18100
    To use with the Curt Cargo Carrier # C18100 I highly recommend the Curt Cargo Bag # C18210. This is a waterproof soft-sided bag that provides up to 12-1/4 cubic feet of storage space and dimensions that match this carrier perfectly. It features integrated straps to secure it to the platform and flaps that keep any water from sneaking in by way of the zipper. I like soft containers like this because they can be easily folded up for storage when not in use and they just give you more flexibility...

  • Waterproof Cargo Bag to Use with Curt Cargo Carrier # C18110
    The best fitting cargo bag for the Curt cargo carrier # C18110 that you referenced would be the Curt # C18210 which is waterproof and measures 56 inch long by 18 inch wide, and 21 inches tall. This would be a bit longer than your carrier but still would still work great.

  • Recommended Cargo Carrier to use with the Curt Cargo Bag # C18210
    Since the Curt Cargo Bag # C18210 that you referenced measures 56" long x 18" wide x 21" tall the 24x60 Curt Cargo Carrier # C18151 is compatible with it and is what I recommend going with. This cargo carrier will fit 2" hitch receivers and has a 500 lb weight capacity. You will want to verify the Tongue Weight (TW) capacity of both your trailer hitch and your vehicle to make sure that you can carry up to the 500 lbs though. The shank has a 2" rise and has a distance of 9" from the center...

    The Curt hitch-mount cargo carrier # C18109 measures 59-7/8 long x 19-1/8 wide on the inside of its side rails so with it you can use a cargo bag like the Curt waterproof bag # C18210 or the similar but slightly larger 15-cubic-foot bag # C18211. Since cargo bags are soft and flexible in some cases you might actually want a bag that is larger than the basket's footprint to allow for some "wiggle room" to allow an easier fit for your cargo items that might be especially tall. But strictly...

  • Recommended Hitch For Carrying A Cargo Rack On A 2022 Subaru Crosstrek
    For your 2022 Subaru Crosstrek, I recommend the # e98912. This American made hitch is rated up to 3,500 pounds towing and 525 pounds of tongue weight. You will need to confirm your capacities in your owner's manual though, as this may be higher than your vehicle is rated. However, with the 2" receiver, this will have absolutely no issue carrying the 19x60 Curt Cargo Carrier # C18100. With the Curt # C18100 being as light as it is. you should be able to carry a good amount...

    Tie-down straps can certainly be added to the Curt Cargo Bag # C18210 that you referenced for even more security but one of the great things about this particular bag is that it actually features 6 integrated straps that are designed to hold it in place inside a cargo basket like the excellent Curt # C18100 that you also mentioned.

    If you check out the attached review video of the Curt Cargo Bag # C18210 (about the 2:00 mark) our video team member already measured the zippers to have a hole that is about 3/8" diameter so you will just need a padlock with a shackle diameter smaller than 3/8" to use with the bag. The Master Lock Laminated Steel Padlock # ML101 has a shackle diameter of 5/16" so it should work just great for your application. If you would like a smaller diameter shackle then I recommend the Master Lock...

  • Can I Carry A Hitch Mounted Bike Rack Or Cargo Carrier With My 2018 Chrysler Pacifica Hybrid
    Great news! We do offer a a hitch for your 2018 Chrysler Pacifica Hybrid. I recommend the Curt Class III Round Tube Receiver Hitch part # C13383 because the 2" hitch will be the most versatile when it comes to accessories like bike racks. There are more options to fit the 2" hitch compared to the 1-1/4" hitch. The Curt 2" hitch is a glossy black powder no drill-installation hitch that can handle up to 400 lbs of tongue weight.

    Appreciate the photo of your 2015 Nissan Xterra (not to mention the view), and while there is a way for you to carry cargo along with a kayak, it isn't possible to add both on your factory roof rack because the bars simply aren't wide enough. Your Xterra has 32 inches of crossbar space and there isn't a roof bag or cargo box narrow enough to go with a kayak carrier.

    Tthere would likely be some interference using the Rightline Gear Sport 2 # RL100S20 with sliding doors like on your 2014 Honda Odyssey and it would not be a recommended fit for its naked roof. To haul extra cargo with your Odyssey, I recommend installing Draw-Tite hitch # 75270 and then Cargo Carrier # C18150 as well as Cargo Bag # C18210 and Anti-Rattle Hitch Lock # 63232. The other option is to install a roof rack, though that will be a more expensive and noisier option. If you are...

    While the tube opening at the front of the Carpod Walled Folding Cargo Carrier # M2205-01-02 does closely resemble a hitch receiver, it cannot be used to mount an additional accessory like a bike rack. For a bike rack and cargo carrier that CAN be used together, I recommend taking a look at the Hollywood Racks Sport Rider SE2 # HR1450Z-85. This unique setup includes both a 2-bike platform rack and a 52-1/2 inch x 15-9/16 inch cargo basket that can attach to it. Either option can also...
