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 #2 in Best Roof Cargo Boxes

Yakima SkyBox NX XL

4.6

$849as of Jun 8

The SkyBox NX XL is the value pick at the top of the size chart: 18 cubic feet of genuinely usable space thanks to a flat floor, a taller nose for small bags, and a stiff three-rib lid, all for less than Thule's comparable box. It is heavy and a touch noisier with a sunroof open, but it is the best all-rounder for the money.

Strengths

— 18 cu ft of usable space, undercutting the comparable Thule boxes on price
— Flat, flush interior floor lets large items slide in without snagging straps or ski edges
— Taller nose stores duffels and totes up front where space is usually wasted

Watch-outs

— Reviewers noted more wind noise with a sunroof open than some rivals
— At 53 lb it is the heaviest box here to lift onto the roof
— Mount is good but lacks the torque indicator of Thule's PowerClick

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.

Yakima SkyBox NX XL

Matches the Thule Motion 3 XL and Thule Force 3 XL at 18 cu ft while costing less than the Motion, making it the best-value large box. Its flat floor is roomier in practice than the boxes it competes with, and it dwarfs the budget Yakima RocketBox Pro 14 and the low-profile INNO Wedge 660.
