PVC-Lined Water-Resistant Fabric

Closeup of Ace Jr cargo bag material and inner PVC layer

The roof-mounted cargo bag is made of Hydrotuff material - 600-denier, woven polyester backed with a PVC inner layer that keeps out moisture. The semi-coated mesh material blocks 98 percent of UV rays to help prevent fading.

Welded seams help keep water out so your gear stays dry.

Under-the-Flap Zipper Placement

Urethane-coated zipper on Ace Jr cargo bag

This bag's zipper is protected under a flap, so it is sheltered from the rain.

Ace Jr cargo bag unzipped on top of vehicle

The zipper also runs three-quarters of the way around the roof bag, so you can easily load up the bag or access your gear.

Roof Rack or Bare Roof Mount

The Ace Jr cargo bag can be used with either a roof rack or cargo basket or on a bare roof.

Rightline Gear Bag on Side Rails

Just attach the bag to your side rails, crossbars or cargo basket using the four included straps. The attachment straps thread through D-rings on the bag for added security.

Rightline Gear Bag on Naked Roof

Or if you have a bare roof, you can hook the included car clips to the door frame weather molding and thread the attachment straps through the D rings on the four corners of the bag. Your car doors will close easily over the straps.

This kit includes clips that attach to the bag straps and then hook over the ledges or rain gutters at the tops of your doors. A roof protection pad (RL100650 - sold separately) is available to keep the bag from sliding around and to protect the top of your vehicle from scratches.

To lock up the bag, run a Rightline Gear locking cable (RL100640 - sold separately) through the cutouts in the zipper pulls. Then, if you want to lock the carrier to your roof, run the cable around your roof-rack rails.

Everything was dry and secured on the roof of the car.


It did it’s job and kept everything inside dry. Lots of room.


Storage bag was great-good size for our needs.


I love it. However don't let the package be so discreet


I absolutely do NOT recommend this bag. Details below.

Worst bag. Ever. The bag had a lot of promise for $53! The bag seemed to be high quality with a thick outside, nice sturdy zippers, and a few great reviews, however, I must have received a dud or I was punked.

I used this bag for a two day trip from Baltimore to New Orleans with mild scattered thunderstorms. As you can see in the photos, the interior liner of the bag, that makes it waterproof, completely deteriorated which allowed copious amounts of water into my belongings. In addition to the liner deteriorating, holes were formed in the bag...holes that I could fit my fists through.

Thanks to this bag I had wet clothes, ruined books, and a few damaged electronics. I thought spending $53 on a bag would get me a quality bag. I guess I was wrong.

I love etrailer and will continue supporting them, but etrailer you need to consider taking this product out of your inventory. Seriously. etrailer, please let me know if/how I can return this bag for a refund or exchange for a better quality bag.

Side Note: Anyone who has this bag, be sure to bind the zip pulls together by intertwining the pulls -- this will ensure the bag will not open because of the wind causing the bag to flap and slowly pry open the bag.


Very Pleased with the performance. Drove from Pennsylvania to Arkansas 900+ miles through winter storm Helena. I used it with the Non-Skid Pad on a 2016 Honda Civic, bare roof. Everything stayed dry, no water leakage anywhere. It was roomier than I had expected, I managed to get a twin size futon, memory foam mattress topper, quilts, blankets & afghan, a husband pillow and a couple throw pillows in it, granted everything was compressed and tied tight, but it fit easily. My only ONLY negative is with the straps, I was not able to get them tight enough to suit so I added 2 additional (the blue ones) straps with ratcheting closure. All straps went through the car with no problem and the carrier did not budge! I did duck tape the front edge of the non-skid mat to keep it from flapping in the wind and making noise.


Very durable and well made product that has held up well over long distance trips in summer rain and winter snow (about 7000 miles in total). It has developed some small holes where it was chafing with the rack basket hardware due to my own fault, but I would definitely buy another one. It fits a ton and is great for extra vehicle storage when needed and folds up small when not being used.


I bought this roof top carrier to take my son to Oregon. When we stopped for our 3rd night I noticed one of the straps was ripped off. Luckily I had eXtra tie downs. When we emptied the bag I noticed the inside of the bag was disintegrating. By the time we got to Eugene the bag was worthless and we threw it out.
The hitch I bought worked well. We had a bike rack on with 2 bikes and that's pretty much all its used for.


Excellent for what I needed it for we traveled a little over 700 miles round trip two times and never had a issues ..


Loved it until I notice 2 of the tie down points on it started ripping. Thankfully it was on our way back home because we hit rain and got some of the luggage wet.


This bag worked perfectly for our 2500 mile drive to and from Florida. Very easy to use and the service at Etrailer is amazing! I called several times for help and each person I spoke to was very helpful and knowledgeable. I highly recommend this roof carrier and Etrailer!


I'm very pleased with this cargo bag. Has easily handled several long-range trips. Probably better quality than I was expecting. I would buy this item again. Shipped promptly. Good followup by etrailer.


It's not as great as a pod. And don't recommend using in the rain. It did leak a lot when we used it returning from Christmas from my paren'ts. So got home with a roofbag full of wet clothes.
Had no issues with it in dry weather. I usually just put soft gear in it like clothes, sleeping bags/pads.


We used this the weekend after it arrived for a 600+ mile road trip. The mounting instructions help to clarify the strap configuration, and the bag itself is quite roomy. We did not encounter precipitation so I cannot attest to its water-tight attributes, but it did the job well and we are happy with the purchase.


Arrived in good time. Easy to pack and attach to the car (using enclosed directions) even though I don't have a roof rack. Didn't encounter any rain, but it looks sturdy enough and well-made to withstand some serious downpours.


Bag worked well thru heavy rain and all stayed dry inside. Straps and buckles were not that good and did not hold. I ended up using my own ratchet straps instead.


They fit perfectly on my crossover. The instructions where easy to follow and took no time at all to install. This allowed my son and I take my wife on one last special trip together. Great products, thanks so much.


Great product! Holds a lot of gear! Everything stayed dry even though we drove through some heavy downpours! Would gladly recommend this product!


Pretty fast delivery, I was ordering it on Saturday night and got it at my door Tuesday afternoon.
I am planning to use it for a trip to Canada. It looks like it fits good on top of my Jeep Patriot.


I have used this bag several times and no problems. Even drove through a hurricane and no water got in. Great bag!


Grain of salt this review. I used it once. It was great the one time I used it. I haven’t used it since then. I’m confident it will work next time too


We used it to go camping and we were
able to put all of our clothes and blankets in the bag and we had room for extras. It worked great and we were very happy with it. This is a great product and we are very happy with it.


Love it. Works great. Have used it 2 times in the rain and not a drop got in on the luggage. Very happy with it.


Works well, but we did have a bit of a leak during a very hard rainstorm.


The lining came out and everything got wet on the first trip

  • Comparing Rightline Rooftop Cargo Bags - 10 Cu. Ft.
    The main difference between the Rightline Rooftop Cargo Bags - 10 Cu. Ft.; Ace Jr part # RL100A50, Range Jr part # RL100R50, and Gear Sport Jr part # RL100S50 is their ability to keep out water with the Ace Jr being the worst and the Gear Sport being the best. The Ace Jr is just water resistant whereas the Range Jr and Gear Sport are waterproof. The Ace Jr and Gear Sport also have a drawstring sack to store the bag in while not in use. I recommend the Ace Jr part # RL100A50 as the best...

  • Recommended Cargo Bag for 2016 Ford Escape with Panoramic Roof
    I looked up an online copy of your 2016 Ford Escape's owner's manual and it states that you are limited to carrying 45 pounds on the roof rack if you have a glass roof an that no weight should be on the roof itself. You should verify with your printed copy but if what I found checks out you can use a roof bag to carry additional cargo as long as you're within the weight limit. I recommend the Rightline Gear Ace Jr # RL100A50. It'll install onto your Escape's crossbars and hold up to...

  • Luggage Carrying Options for a Buick Rendezvous Without a Roof Rack or Bars
    You'll be looking for a roof bag that is compatible with a naked roof. These will connect either inside the vehicle with a clip or to the door jamb of the vehicle to provide a temporary rooftop storage solution. I recommend Rightline Gear's Ace Junior, part # RL100A50 as a great, small option that installs to your door jamb. It adds about 9 cubic feet of storage to the roof of your vehicle, and at 36 inches by 30 inches, it's small enough to be carried off the vehicle into the house....

  • 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....

  • Recommended Rooftop Cargo Bag For 2021 Subaru Impreza With Factory Crossbars

I recommend looking into Rightline Gear 4x4 Duffel Bag - Waterproof - 2.1 cu ft - 25" x 11-3/4" x 13" # RL100J86-B as this is the only cargo bag that will easily fit inside your current roof rack.

  • Rooftop Cargo Bag for 2001 Toyota RAV4 With Luggage Rack
    There is a rooftop cargo bag that will work for your 2001 Toyota RAV4, but none that are going to fit directly between the 27" x 38" space you mentioned; there will need to be a bit of overhang on the rails, unless you don't fill the bag all the way up and you have some space to squeeze it in. The best option is the Rightline Ace Jr Rooftop Cargo Bag # RL100A50, which is 36" long x 30" wide, so you would need to turn it sideways to get it to fit in the space you have, and there will be...

  • Can MaxxTow Dual Hitch Receiver be Used to Raise Height of Cargo Carrier on 2020 Kia Telluride
    You can, but it's worth noting that the MaxxTow Dual Hitch Extender MT70070 will reduce the weight capacity of your trailer hitch by 50% so if you're already hitting the ground with your 2020 Kia Telluride then I'm not sure if this will improve anything. In all honesty it would be much more effective if you were to transfer that extra weight to a different part of your vehicle like your roof with a roof rack system or a more cost effective cargo bag like part # RL100A50 that uses clamps...

  • What Cargo Bag and Cargo Box do You Recommend for My 30-Inch Crossbar Spread on My 2012 Mazda 5?
    If you have crossbars that are 30 inches apart on your 2012 Mazda 5, the best option for a cargo bag is the Rightline Ace Jr Rooftop Cargo Bag - Water Resistant - 10 cu ft - 36" x 30" x 16" # RL100A50. Since the dimensions of the Ace Jr measure 36" long x 30" wide, you will be able to mount the bag sideways (with the straps toward the front and back of the vehicle) between your crossbars. However, since it will be a close fit, you may have to tuck a little bit of the edges under the front...

  • What Cargo Bag Installs Directly to My Bare Roof on My 2013 Kia Soul?
    I have a great solution for you. As far as the CargoSmart Soft-Sided Car Top Carrier - Water Resistant - 15 cu ft # CS94FR, it does require crossbars in order to transport it on your 2013 Kia Soul with a bare roof so instead I recommend a bag that can be attached to a bare roof as that will be the most cost effective. I recommend the Rightline Ace Jr Rooftop Cargo Bag - Water Resistant - 10 cu ft # RL100A50. This cargo bag is great because you do not need to purchase additional crossbars...

  • Recommended Roof Top Cargo Basket and Cargo Bag Combination for a 2017 Honda Pilot
    If you are just looking for a rooftop cargo bag then you actually have quite a few more options. The only time that you are restricted to a bag that sits on your crossbars is if you have a window on your roof like a sun or moon roof. In that case I recommend putting the cargo bag in a cargo basket on the OEM crossbars of your 2017 Honda Pilot. If you are needing a cargo basket then I recommend going with the Thule Roof Mounted Cargo Basket # TH859XT. This is confirmed to fit your Honda...

  • Roof Bag Recommendation for Hatchback with Roof Rack
    The CargoSmart Soft-Sided Car Top Carrier # CS44FR uses straps that you loop around the crossbars of your roof rack for the installation. For something with clips you'll want to check out the Rightline Ace Jr Rooftop Cargo Bag # RL100A50 but these clips are designed to fit in the door jambs of your doors so I don't recommend placing them at the hatch. I really like the Rightline bags for the clips but if you already have a roof rack then definitely go with the CargoSmart because you'll...

  • Will The Inno Shaper 80 Fit The Rhino Rack Vortex Aero C-Channel On My 2012 Audi A3 Hatchback?

So, yes the Inno Shaper 80 will fit your Rhino Rack Aero Bar Setup!

  • Is There a Car Top Carrier That Will Work on Multiple Vehicles
    In regards to using a rooftop cargo carrier (cargo box/cargo bag) on multiple vehicles, it really comes down to the roof type of said vehicles.

  • What Hard or Soft Shell Roof Storage Methods do You Recommend for a 2017 Jeep Grand Cherokee?
    For a great hard-shell cargo box that fits your Rhino-Rack Vortex Aero crossbars, I recommend the Inno Box 2020 - 14 cu. ft. # IN86FR. The 2020 comes with a dual-opening lid to comfortably open the box from either side. Also, it comes an injected-mold construction to withstand debris impacts, scratches, and UV rays. Not only does this box attach to your Vortex Aero crossbars, you also have the proper crossbar spread required to mount the box. This is because I confirmed that with your previous...
