The short answer

INNO Wedge 660 comes out ahead by a clear margin (4.5 vs 4.0). 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
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

Yakima SkyBox NX XL
Ranked #5 in Best Roof Cargo Boxes
Yakima SkyBox NX XL
3 sources2 derived$849as of Aug 1

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

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.
