Wedge 660
INNO
The INNO Wedge 660 is tailored specifically for drivers prioritizing low-profile aerodynamics, highway efficiency, and overhead clearance. Unlike bulbous, high-volume haulers, this box hugs the roofline with an 11-inch vertical height, reducing wind drag and cutting down on cabin noise. Testing outlets consistently praise the Wedge 660 for its sharp styling, exceptional build quality, and ability to clear standard residential parking garages when mounted on mid-size SUVs. Underneath its sleek exterior, the Wedge 660 uses an innovative manufacturing process utilizing multi-layer plastics that yield surprising stiffness. Reviewers consistently note that the lid opens smoothly with virtually zero wobble, shutting with an authoritative latching click. Mounting is managed via INNO's Memory Mount system, which allows users to set clamp tension once; subsequent installations require only flipping a cam lever into place. Dual-side opening adds convenience during loading. The obvious compromise with any low-profile box is vertical volume. While it easily swallows downhill skis, snowboards, trekking poles, and low-profile camping mats, it will not accommodate tall hard coolers, thick camp totes, or overstuffed duffel bags. It appeals strongly to skiers and year-round adventurers who want minimal impact on vehicle handling, but anyone needing to pack deep cargo containers should look toward taller, traditional shapes. **Highlights** - Ultra-low 11-inch vertical profile clears low garages easily - Memory Mount system allows rapid, tool-free crossbar reinstallation - Rigid, high-gloss lid minimizes twisting when lifting open - Aerodynamic wedge shape reduces highway wind resistance - Dual-sided opening accommodates straightforward gear organization **Watch-outs** - Restricted vertical clearance prevents hauling tall totes or coolers - Premium pricing relative to its modest total internal capacity - Gloss finish is vulnerable to surface scratches from low branches

SkyBox Carbonite
Yakima
The Yakima SkyBox Carbonite is a dependable, utilitarian staple across the outdoor recreation community. Built for drivers who want straightforward, durable storage without unnecessary cosmetic frills, this workhorse box has spent years proving its reliability in tough conditions. Available across a wide spread of volumetric sizes from 12 up to 21 cubic feet, it offers options tailored to everything from compact sedans to full-size overland rigs. The exterior features Yakima's textured Carbonite dimpled lid, which provides decent structural stiffness while hiding cosmetic scratches from trail brush and loose gravel far better than glossy finishes. Independent reviewers emphasize its practical, tool-free mounting system that works reliably across aero, round, and square crossbars. The SuperLatch system physically separates latching from locking, meaning the key cannot be removed until all locking points along the rim are fully engaged, preventing accidental highway spills. The aging design does show some drawbacks when compared to modern updates like the NX series. The internal mounting clamps occupy more vertical space on the cargo floor, creating small obstacles around which gear must be packed. The lid can also feel somewhat heavy and flexible on the largest models, requiring deliberate guidance to latch. Still, for proven durability and high volume per dollar, the Carbonite remains an enduring favorite. **Highlights** - Textured Carbonite finish resists and masks cosmetic scratching - Wide variety of capacity options ranging from 12 to 21 cubic feet - SuperLatch security ensures all pins are engaged before locking - Dual-sided access eases packing across tall vehicle platforms - Proven durability under long-term exposure to sun and winter elements **Watch-outs** - Internal mounting hardware protrudes higher into usable floor area - Lid shows torsional flex on the larger volume configurations - Bulkier external profile generates noticeable drag on smaller cars
