The Thule Motion 3 XXL is built for serious hauling—whether it's gear for the whole family or long road trips. With a cavernous 21 cu ft (600 L) capacity, this is the largest box in the Motion 3 family—and it still looks sleek and rides quiet.
Fits 5–7 pairs of skis (up to 215 cm), 3–5 snowboards, duffels, camping gear—you name it. Still clears most SUV rear hatches and works with all major crossbars.
It mounts quickly with Thule’s PowerClick system—tighten until you hear the click. Dual-side opening and SlideLock make loading and securing gear easy from either side of your vehicle.
Outdoor Sports Center includes free installation with every Thule box we sell. We’ve been selling and installing Thule longer than just about anyone—when it comes to rooftop cargo, we’re the local experts. Come see us or give us a call at (203) 762-8797—we’re happy to talk through box and rack options with you.
