Thule Motion XT XL - Best Overall
The Thule Motion XT XL is the cargo carrier I now own. 18 cubic feet swallows our family's week-long gear including sleeping bags, dog crate, two duffel bags, and tent. The aerodynamic shape produces less wind noise than boxier carriers - measured 6 dB quieter than my previous brand at 65 mph. PowerClick mounting system clamps to crossbars with one hand using a torque indicator that clicks when properly tightened, eliminating overtightening. Dual-side opening means I can load from either side of the car. Security locks on both sides keep contents safe. The interior felt-lined floor protects gear during transit.

The full reviews
Thule Motion XT XL - Best Overall
The Thule Motion XT XL is the cargo carrier I now own. 18 cubic feet swallows our family's week-long gear including sleeping bags, dog crate, two duffel bags, and tent. The aerodynamic shape produces less wind noise than boxier carriers - measured 6 dB quieter than my previous brand at 65 mph. PowerClick mounting system clamps to crossbars with one hand using a torque indicator that clicks when properly tightened, eliminating overtightening. Dual-side opening means I can load from either side of the car. Security locks on both sides keep contents safe. The interior felt-lined floor protects gear during transit.
Yakima SkyBox NX 18 - Best Dual-Side Opening
The Yakima SkyBox NX 18 competes directly with the Thule Motion XT and many users prefer it for build quality. The dual-side opening lets you access cargo from either side. SuperLatch security system locks both sides simultaneously. The interior dimensions slightly favor long items vs the Thule which favors wider items. At equivalent price the choice comes down to whether your typical cargo is long (skis, snowboards, fishing rods - favor Yakima) or wide and bulky (favor Thule).
INNO Wedge Plus - Best Aerodynamic
The INNO Wedge Plus prioritizes aerodynamics over capacity. The teardrop shape produces noticeably less wind drag than the Thule and Yakima offerings - my MPG was 1.5 mpg better with the INNO than my Thule on equivalent highway runs. 13 cu ft suits 3-4 person trips or as a supplementary carrier alongside trunk space. Quick-mount system installs in under 10 minutes. For users prioritizing fuel economy on longer trips this is the right choice.
RoofBag Explorer - Best Soft Bag
For occasional use or budget-constrained buyers, the RoofBag Explorer soft bag delivers real utility at. 15 cu ft capacity, 100% waterproof rated, and folds to the size of a shoebox when empty. The trade-off: no security (cannot lock), and the bag must be strapped down through the car interior with the doors closed, which is annoying for daily use. For 1-2 trips per year families this is the right tool. Heavy users should step up to a hard shell.
Thule Force XT Sport - Best Compact Hard Shell
The Thule Force XT Sport at 11 cu ft is the right size for smaller vehicles, single-driver use, and quick weekend trips. Same Thule build quality as the Motion XT in a smaller package. Dual-side opening, central locking. The smaller profile means lower wind drag and fuel cost than larger Thule offerings. For most weekend warriors and 2-3 person families this is sufficient capacity. For 4+ person family vacations step up to the 18 cu ft size.
What matters most
What to consider
Match capacity to your trips. 11-13 cu ft for couples and weekend use. 16-18 cu ft for 4-person family vacations. 20+ cu ft for 5+ people or extended trips.
What to consider
Hard shell vs soft bag decision. Hard shells for security, weatherproofing, and frequent use. Soft bags for occasional use, easy storage, and budget priority.
What to consider
Crossbar compatibility is critical. Verify your car's roof rack crossbar spacing matches the carrier's mounting points. Most premium carriers (Thule, Yakima) include adapters for various crossbar profiles.
What to consider
Aerodynamic shape pays off on long trips. Teardrop and low-profile shapes reduce fuel cost by 8-15% vs boxier carriers. Over a multi-day road trip the fuel savings can pay for the upcharge.
What to consider
Lock quality matters for security. Cheap locks are easily picked or defeated. Premium carriers (Thule, Yakima) use solid lock cylinders with security ratings. For valuable gear, prioritize lock quality over capacity.
Frequently asked
Consider the volume of gear you typically carry. For weekend trips, 15-16 cu ft is sufficient. For longer trips or bulky items like camping gear, 18 cu ft or more may be needed. Also check your vehicle's roof load capacity.
Most carriers fit vehicles with factory or aftermarket crossbars. Check the carrier's mounting system compatibility with your crossbar shape (round, square, aerodynamic) and spacing. Some carriers require specific crossbar spread.
Expect a 10-20% decrease in fuel economy at highway speeds due to aerodynamic drag. Aerodynamic designs like the Thule Motion XT L minimize this impact. Removing the carrier when not in use helps save fuel.
Most carriers have integrated locks that secure the lid and mounting system. However, no lock is completely theft-proof. Use additional cable locks for high-value items and park in secure areas.
