Motion 3 Cargo Box delivers sleek aerodynamics and versatile storage across all adventures

What Our Gearhead® Experts Are Saying:


"I’ve used the Motion 3 Cargo Box for everything from weekend ski trips to cross-country road travel. It installs fast, opens from either side, and the aerodynamic shape keeps my fuel use in check. With the variety of sizes, it fits nearly any setup or trip."


Built for seamless travel across every season, the Thule Motion 3 Cargo Box balances rugged performance with refined design. Whether we’re packing skis for the mountain, duffels for a road trip, or camping gear for the desert, it offers a range of volumes and profiles to fit our setup perfectly. The aerodynamic shape helps cut wind resistance and preserve fuel efficiency, while the low-profile options deliver garage-friendly clearance without sacrificing capacity.


Engineered for simplicity and security, the Motion 3 features one-handed opening from either side, a quick-mount system with torque feedback, and a SlideLock system that ensures the lid is locked and latched properly. Inside, premium accessory compatibility—including lights, duffel sets, and liners—adds comfort and organization to our travel routine. From daily use to big expeditions, this is the cargo box we trust to carry it all.
