The short answer

INNO Wedge 660 comes out ahead by a narrow margin (4.5 vs 4.3). The gap is mostly about Skiers and minimalist packers who want a sleek, quiet, low-clearance box for flat gear rather than maximum volume. — read the strengths below before deciding.

Higher ratedRanked #1 in Best Roof Cargo Boxes

INNO Wedge 660

4.5

3 sources1 derived$866as of Aug 1

At 11 inches tall, the INNO Wedge 660 is the low-profile specialist: the quietest, most aerodynamic and best-looking box here, and a natural fit for skis, poles and flat gear. Volume is the sacrifice, since the shallow 300-liter interior handles bulky items poorly. Skiers and minimalists who want a sleek box that barely changes their roofline have no better option.

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

Ranked #3 in Best Roof Cargo Boxes

Thule Force 3 XL

4.3

3 sources2 derived$929.95as of Aug 1

Thule's value workhorse gives you the same 18 cubic feet and PowerClick mount as the pricier Motion, wrapped in a rugged AeroSkin shell built to last for years and keep gear dry in foul weather. The Force 3 XL pays for that with a boxier, slightly noisier shape and plainer looks. On 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.
