Why this product
Why the Yakima SkyBox NX 18?
At 18 cu ft and 45 lbs, the SkyBox NX 18 offers the flat bottom interior that maximizes usable space — less wasted volume in tapered corners. Improved aerodynamics keep highway noise manageable. The downside? At this price point, you're competing directly with the Thule Motion 3 XL, which offers dual-side opening and a more refined mount system.
