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 #1 in Best Roof Cargo Boxes

Thule Motion 3 XL

4.7

$1,099.95as of Jun 7

The Motion 3 XL is the do-everything premium box: 18 cubic feet, a torque-limited PowerClick mount that confirms a secure install, and the slickest one-hand operation in the category. It is expensive and long, but reviewers across the board rank it at or near the top for build quality and usability.

Strengths

— 18 cu ft (about 500 L) swallows gear for ski trips and camping without being overly tall
— PowerClick mount has a torque indicator that clicks audibly when securely attached
— Wide single-hand handle and DualSide opening make loading from either side easy

Watch-outs

— List price near $1,150 is among the highest in the category
— At 84.7 inches long it can crowd a roof and block a rear hatch on shorter vehicles
— Heavier than budget boxes at 51 lb to lift onto the roof

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 Motion 3 XL

The premium benchmark, edging out the Yakima SkyBox NX XL on build quality and mount refinement though the SkyBox matches its 18 cu ft for less money. It is pricier and slightly larger than the Thule Force 3 XL, far roomier than the budget Yakima RocketBox Pro 14, and much taller than the low-profile INNO Wedge 660.
