Rated 5 out of 5 by from Welcome to the Big League You can stow anything in this bad boy. I love mine. I used it to go to the Grand Canyon and had all kinds of stuff packed up in the SkyBox. It's easy to install and is quiet on the road. Note to self: Do not get inside the box to show your son that it can easily fit a grown man with room to spare. Hypothetically speaking, you could be trapped inside until you figure out how to unlatch it from the inside. But I would never have done such a ridiculous thing. BUY IT!

Rated 4 out of 5 by from Almost Waterproof This product fit perfectly on my 2014 Subaru Forester (SkyBox 21). I moved the factory crossbars so the front was as far forward as it would go, and the back one was just behind the back support pot (where it attaches to the roof). I took it on a few 180 mile trips, at least twice through driving rain, and only a bit of water got inside. They don't advertise this as waterproof, merely weather resistant. I was pretty impressed, based on the crazy wind and rain I experienced. Still, for the price point, you would think they would figure out a way to put a rubber gasket in there or something to make it seal a bit better, keeping out those last few drops. My workaround for the important stuff was to just buy some 55 gal contractor trashbags (which I already had, and wrap each item in there first). For any of you with kids, this model was enough to completely fit a Britax Jogging stroller with the rear wheels on, I found it was easier to take the front wheel off, since it's quick release anyways. It also fit right between the ridges on the inside so it didn't move around. They do recommend everything is tied down inside, which I did do.There are some included tie down points. As for gas mileage, this does hurt it a bit. I have meticulously tracked the gas mileage on my Forester, and have done this 180 mile trip numerous times in the past, and here's the results: I usually would get about 28.8-29.5MPG driving in pretty mountainous terrain at about 65-70MPH. With the cartop carrier making this trip a few days apart I got 24.64MPG one direction and 26.4MPG the other. One direction I hit way worse wind. These are all based on miles driven/gallons of gas added, not the trip computer. Either way expect a 2-4MPG hit on whatever you normally get. Still a better value than driving a larger SUV. Anyways, the 4 stars is merely the for the fact that it didn't keep all the water out (for the price). If they fixed that it would be a 5 star product. Oh, and for the 2014 Subaru Forester, when I say it perfectly fit, I mean that it cleared the hatch of my Premium (no auto lift gate) and I was even able to put the antenna back in (after initially removing it to load). I ended up saving a lot of money on this when REI was running a 20% off sale for member. So I would recommend waiting for that if you can. REI brought it out to my car, and put it on the roof, but I had to physically install it. I guess they don't want the liability. I am a relatively fit 5'9" male and I was able to easily remove it from the top of my car myself. If you had someone else helping, it would obviously be easier. I would recommend this product though for anyone who needs the extra storage.

Rated 5 out of 5 by from Makes all trips short and long so much safer. Love it,....holds so much stuff.makes the inside of my suburban cleaner and not cluttered.

Rated 4 out of 5 by from Holds everything - Nordic, blankets, broom, etc. I have brought this to spokane, tri-cities, and now hope to go to white pass this week. It makes my suburban height at ten feet, but if I pack it right, no sliding around. It is quiet on freeways and easy to put on and off. I needed a three step ladder. I let REI install it and it took them with rails about one hour. Sweet!

Rated 5 out of 5 by from Very versatile Large and perfect! I have a 16 carbonate skybox, but needed a bigger one. Very strong build! Drove around 6,000 miles on a road trip and it was secure and quiet the whole way. Having a Honda Ridgeline this thing blew the truck around a bit when traveling through Nebraska and Wyoming when the winds were pushing 60-70 MPH gusts. That's not a negative because that's expected. Skybox fits a ton of stuff and closes easily.

Rated 4 out of 5 by from Difference between SpaceCase Generally a good product. It fixes an annoyance with the Spacecase to allow for better opening and closing of the box; however, it is shorter, so some paddles may not fit compared to the SpaceCase. It also does leak a little more than the Spacecase, but again it isn't that big of a deal if you're putting stuff that can get wet during really hard rain. It is much easier to put on and take off due to the mechanism used. It is nice being able to open both sides, but would be great if you could take the key out and leave it have to leave the key in. One last item...The space case has a better "tub" to sit items in it. Things slide around a bit more with the skybox and need to be tied down, which Yakima did a better job of building tie down points (straps are separate) into the bottom part. It is a little heavier than the SpaceCase (at least it seems that way when carrying.)

Questions & Answers

Any experience in attaching this to the factory roof rack & cross bars on a 2012 Toyota 4Runner? Does it have any contact with the aerodynamic antenna at the back end of the vehicle's roof?

Asked by: Grandpa Steve
Steve: Have you had any luck finding a cargo box for your 4Runner? I have a 2014 4Runner and my 10 year old Yakima box bumps into the antenna but also (and worse) bumps into the fairing (I think that's what it's called) at the top of the tailgate forcing it to open less than normal. I'd say it's about 4"-6" decrease in clearance causing me to always bump my head. Can't seem to find anyone who makes a compatible cargo box.

I have a 2016 Jeep Grand Cherokee, have the factory MOPAR crosbars installed. Also have sunroof and rear hatch door. What is the longest SkyBox (21, 18 or 16) that will fit and not interfere with rear hatch door opening or the sunroof opening.

Asked by: Willie
To determine hatch clearance, position your front crossbar in the foremost position and measure from center bar to open hatch. The clearance needs to be at least 52" for a Skybox 16 or 57" for a Skybox 18 or 21. Detailed fit information for your vehicle is not available in the Yakima Fit Guide. We recommend contacting the vendor directly for additional details.

Will the Yakima Skybox 21 fit on a 2005 Chevrolet Suburban (using the factory cross bars) and also a 2013 Lexus RX 350 (using its factory crossbars)?. I would like to switch from each of these vehicles without having to install custom roof racks.

Asked by: craigspin
Not sure about your Suburban, but I have a 2010 Lexus RX 350 (same body as your 2013) and can confirm that this box is too large. When installed, access to rear hatch is blocked about 3/4 the way up.

I currently have a 2016 Honda CRV Touring edition with the power lift gate.  What are the options for roof top cargo boxes that won't require additional cross bars or hardware? 

Asked by: mansmann
All of our car top boxes require a crossbar, factory or aftermarket, to attach to. To discuss compatibility for your specific vehicle, please call us at 1-800-426-4840.

Will REI install this, including baseline, and cross bars? If so, how much? Does it interfere with trunk opening on a 2016 Acura MDX? 

Asked by: Tj78
Some REI stores offer a paid service to install a Yakima or Thule rack system on your vehicle. Please contact the REI retail store nearest you for details: Hatch interference is calculated by measuring the distance between your front crossbar and the rear hatch when open. This box requires that distance be a minimum 57" to avoid interference.

Will the Skybox 21 fit on my 2012 BMW X5 with factory crossbars? How much weight and I load in the box? If the 21 doesn't fit any suggestions.

Asked by: stephank50
This cargo box is compatible with the factory installed crossbars on your 2012 BMW X5. The maximum load capacity depends on the overall weight capacity for the roof of your vehicle which includes the weight of the SkyBox.
