Updated SkyBox with improved aerodynamics and quieter ride
Last reviewed: April 2026
At a glance
Why this product
At 21 cu ft and 50 lbs, the SkyBox NX 21 is Yakima's largest flat-bottom box — that interior design means less wasted space in the corners compared to curved competitors. Improved aerodynamics keep it reasonably quiet. The downside? 50 lbs is manageable but not light, and Yakima's mounting system still requires more fiddling than Thule's PowerClick.
