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.

I wasn't sure I would need this for the new rack I purchased, but got it just in case. Well, wouldn't you know it, it rained for part of our drive across 4 U.S. states. Although I didn't need to keep everything dry this time (two coolers of food and beer, plus some beach umbrellas and other stuff), I'm glad I have this for that reason. No water got inside the bag. It fit all that stuff and on the way back we piled some beach chairs on top without worry the bag would rip. Sure, you could cut it with a box cutter or knife, but it's pretty tough for normal and expected use. The vinyl is thick and the zippers seem like good quality and it fit nicely within the rack that I also purchased from etrailor with a few inches to spare all around. I've used it for one family vacation so far and can't comment on how long it will last, but I expect it to hold up over time. I don't see why this won't last for years. The straps it came with made it fairly easy to tie down onto the rack.

Its been a year since I bought this and Im still happy with it. I used it again this summer on another drive through multiple states and it performed great. The material and zippers are holding up well.

The cargo bag has worked out really well for us over the last year. Very durable, cavernous and easy to clean.

Good fit to my hitch carrier. Excellent communication from

- C18211

Size charts were accurate and bag fit perfectly on rack. Bag is durable with a heavy duty zipper that seals well. Although the straps for the bag feel a little low quality, they have performed very well and held in place for the duration of transport.

- C18211

Solid, weatherproof, and constructed well. Does just what it's designed to do.

We have owned our Curt cargo bag and hitch mounted cargo carrier for a year. Today, my husband said, "I don't remember what we paid for these, but whatever it was, it was worth it." We have used our carrier for everything from hauling luggage to free up space in our SUV for people, to hauling house maintenance equipment like a power washer. The cargo bag has kept our luggage dry in a drenching, blowing storm. We are in our 70s, and putting the carrier on and taking it off are easy and quick to accomplish. Just a little wiggling to line up the holes to feed the connector rod through. We are annoyingly picky consumers, and this carrier and bag combo is one of our most satisfactory purchases ever.

- C18211

Feels like real quality product, it is really strong material and dosen’t look cheap at all, the only thing is the zipper is kind of hard to go around the corner of the bag when cold.

- C18211

I haul a 34 ' 5th wheel trailer to camp in and it has a receiver hitch . I use a cargo carrier also to haul my pellet smoker and a large plastic tub and lid for the pellets and accessories. I feel more comfortable using a cable lock to secure the smoker to the trailer . I bought this Curt Cargo bag to go over the carrier and the cargo so you can't see the contents or the lock only the bag and the bag is water proof so the contents are protected from prying eyes and the weather. I would definitely recommend this product because it looks good and works well.

Cargo bag is awesome. We frequently use this for our camping trips and i was amazed by how much it helps to protect my stuff from AZ heat and rain. I have even used this in my travel from AZ to LA and vice versa. Zipper is well built and you could tell that it will last a long time. The straps that came with the cargo bag is a huge help, and secures my load without me worrying that it will fall off. Highly recommend this product!

- C18211

Just back from my first trip using this bag. Drove through heavy rain and everything inside was bone dry. I am a little concerned about durability...the stitching one one of the corners gave out on its first use. The bag was far from full, but the stitching pulled apart. I covered it with duct tape and that seemed to hold the rest of the seam in place.

- C18211

Carried this bag on a curt carrier. We traveled 1000 miles with it at 70mph+ speeds. Can’t confirm waterproof yet but it did very great traveling. We use it to carry clothes, pillows, and bags for increased trunk space storage for more value able things. We do wish it had cargo handles on the side or something bc we do carry it in and out of the house for easy packing/unpacking. Overall very happy with it.

- C18211

Awesome product, so glad I got this instead of trying to wrestle with tarps and bungee cords. Totally worth every penny. Was able to fit 5 Carry-on sized pieces of luggage in it with no problem.

- C18211

Customer Service is phenomenal. The Representative was able to look up my past orders in order to ensure the best cargo carrier for my needs. She made a recommendation she felt would be the best fit, which was also reasonably priced and it works great. Shipping was almost immediate following my purchase. I would highly recommend using etrailer to anyone in the market.

Heavy Duty Looks good. Can't wait to use it

Worked wonderfully. Held 6 people’s suitcases when used with the rack. We had to loosen it to open our minivan rear door but that was a small cost. We drove with it over 1200 miles and used the matching hitch rack. Nothing got wet.

- C18211

I have not yet used the bag - for now I'll give it 5 stars. If I think of it I'll come back and update this review after I use it. Received it within 2 days of ordering. I spent a lot of time researching the different cargo carriers and bags sold by etrailer. Chose it because it is larger than others. I wish it came with better straps. I purchased ratchet type straps with hooks to secure it to the cargo carrier.

- C18211

The cargo bag fit perfectly and kept our luggage dry. We will be able to use it again and again with no problems.

- C18211

E Trailer is one of the best on line vendors I have dealt with. Deliveries have been prompt and products have been of very good Quality. Most of my purchases have been CURT BRAND and they have been excelllent quality.

- C18211

For most part has been a really good purchase. It is water resistant but not water proof with a heavy downpour or all day long rain. Just had minor wetness. Strapping to carrier is good and so far sturdy but sometimes confusing so save instructions.

- C18211

Good quality. Fits very well on cargo carrier. I can put my large camping cooler in it & still have lots more storage room for other supplies. Best part is everything stays nice & dry when you zip it up. Ordering & shipping was quick & easy.

- C18211

A little to big compare to the cargo carrier from the same brand but it did its purpose kept everything dry after rainy days on the road

- C18211

This things holds an insane amount of gear and is truly waterproof! We drove cross country through downpours and everything was perfectly dry inside! Not only is the waterproofing nice - but it’s nice to not have to strap down individual items - the straps on it work great and while we had extras on hand just in case we have never needed them!

- C18211

Mine haven’t been used lots, but they hold lots of stuff ! They protect my things from the elements.

- C18211

Well worth the money if you want to keep your luggage dry. We’ve done a number of long distance trips using this in the rain and its held up very well. Its built to last. Very happy with our purchase.

- C18211

A truly reliable product that does everything I would expect it to. I will be keeping this for a long long time, I am sure.

  • Can Water Get in the Curt Cargo Bag # C18211
    The Curt Cargo Bag # C18211 is constructed of a heavy-duty vinyl fabric that does an excellent job at keeping water, dirt, and debris out, but it is closed with a zipper.

  • Recommended Waterproof Cargo Bag for Use with Rola Hitch Cargo Carrier 59502
    The choice of cargo bag to be used along with a hitch cargo carrier like the Rola # 59502 is not super critical. By that I mean that in some cases, depending on the shape and size of the items you need to load, you might actually want an over-size bag that is bit larger than the 22 x 59-inch carrier. This would allow for taller items in the bag to take up any slack. The closest fit in a waterproof bag comes from Curt, their 15-cubic-foot model # C18211. This is shown in the linked video....

The bag has a strong, durable design but it isn't thick enough for those dimensions to vary significantly (literally fractions of an inch).

  • Recommended Hitch Mounted Cargo Carrier For 2013 Ford Flex
    I did some research and found the towing capacity of your Flex is 2,000-lbs. This means the tongue weight capacity will be from 200 to 300-lbs max. That would be the weight of the carrier added to the weight of any cargo in the carrier. I recommend going with an aluminum carrier to take advantage of the lighter weight. The carrier I recommend is the carrier you came from, part # C18100. This is a 19 x 60-inch carrier and weighs just 29-lbs. That gives you a bit of flexibility for your...

  • Hitch Cargo Carrier and Cargo Bag Recommendation for 2018 Toyota 4Runner
    Roof racks and roof cargo boxes/baskets can be expensive pretty quick and since your 4Runner has a factory hitch I'd recommend going with a hitch cargo carrier. Loading and unloading things at the rear of a vehicle hitch is much easier than the roof of a taller vehicle too. The tilting Curt cargo carrier part # C18152 that you referenced would be a fantastic option that would work well. For a cargo bag to attach to this carrier the Curt Cargo Bag part # C18211 would be a great option as well.

If you don't already have one then I recommend going with the Curt Cargo Carrier # C18151 which fits a 2" hitch receiver and measures 59" long x 24" wide and can hold up to 500 lbs of weight.

  • Does the Curt Cargo Bag # C18211 Have a Weight Capacity
    Cargo bags, like the Curt Cargo Bag # C18211 that you referenced, do not have weight ratings on them. The reason being is that they are intended to protect cargo and not really to lift and move cargo. The weight capacity of a hitch mounted cargo bag will depend on a few variables. You will need to know the weight capacity of your cargo carrier, trailer hitch, and your vehicle itself. If the Tongue eight (TW) of your trailer hitch and vehicle is at least 500 lbs then you could potentially...

  • Can Larger Cargo Bag Than Hitch Cargo Carrier Platform Fit Without Issue
    You can use a larger than needed cargo bag on a cargo carrier like what you mentioned. Basically you'd have more cargo room available than needed but as long as you secure the bag down well it won't be an issue at all. You can use a cargo net like the part # C18200 which will easily keep the excess bag and cargo secured. Basically you'll just stretch the net over the bag and it will hold everything in place. I attached a review video for this net for you to check out as well.

For a 2015 Captiva Sport, I recommend going with the Curt # 13594, a Class III hitch that bolts onto the frame to avoid welding, and has a 2" x 2" receiver opening.

I would just make sure that the dimensions 56" long x 22" wide x 21" tall will fit properly on your roof. The main difference between a cargo bag meant for a cargo carrier and one designed for a roof more or less has to do with the position of the straps.
