Ranked #4 in Best Roof Cargo Boxes

INNO Wedge 660

4.4

$799.99as of Jun 7

The INNO Wedge 660 is the low-profile specialist: at 11 inches tall it is the quietest, most aerodynamic and best-looking box here, ideal for skis, poles, and flat gear. The trade-off is volume, its shallow 300-liter interior is poor for bulky items. For skiers and minimalists who want a sleek box that barely changes their roofline, it is the standout.

Strengths

— Low 11-inch profile is the most aerodynamic and quiet box here at highway speed
— Sleek, premium look that several reviewers call the best-styled box in the class
— Memory Mount hardware lets you remove the box without undoing the crossbar mounts

Watch-outs

— Just 11 cu ft (about 300 L) and a shallow 9-inch interior limit bulky loads
— Poor choice for camping totes, strollers, or large duffels
— Hefty shipping fee when ordered direct from INNO

Higher ratedRanked #3 in Best Roof Cargo Boxes

Thule Force 3 XL

4.6

$929.95as of Jun 7

The Force 3 XL is Thule's value workhorse: the same 18 cubic feet and PowerClick mount as the pricier Motion, wrapped in a rugged AeroSkin shell built to last for years and stay dry in foul weather. The trade-off is a boxier, slightly noisier shape and plainer looks. For durability per dollar, it is the smart Thule.

Strengths

— 18 cu ft fits four pairs of skis and poles or bulky camping gear for a family of four
— Tough AeroSkin shell shrugs off years of weather and daily use
— PowerClick mount with torque indicator and SlideLock auto-locking lid, like the Motion

Watch-outs

— Boxier, less aerodynamic shape than the Motion can add wind noise
— 165 lb load and 18 cu ft match rivals, so it wins on value not capacity
— Long 84.8-inch body crowds shorter roofs and can block a hatch

How they stack up

INNO Wedge 660

The low-profile alternative to the tall, high-volume boxes here. It carries far less than the 18 cu ft Thule Motion 3 XL, Yakima SkyBox NX XL, and Thule Force 3 XL and even less than the budget Yakima RocketBox Pro 14, but its 11-inch height makes it quieter and more aerodynamic than all of them, the pick when sleekness and clearance matter more than maximum space.

Thule Force 3 XL

Shares the Thule Motion 3 XL's 18 cu ft and PowerClick mount for less money, trading the Motion's aerodynamic shell for a tougher, boxier one. It costs about $80 more than the Yakima SkyBox NX XL but matches its volume, and it is far larger than the budget Yakima RocketBox Pro 14 and the low-profile INNO Wedge 660.
