The Thule Motion 3 L is your go-to mid-size cargo box—16 cu ft (450 L) of storage in a sleek, aerodynamic shell. Perfect for family trips, weekend adventures, and everyday errands without taking over the roof.
Fits 5–7 pairs of skis (up to 180 cm), 3–5 snowboards, duffels, camping gear—you name it. It clears most rear hatches and balances capacity with no added bulk.
Mounts fast with Thule’s PowerClick system—tighten until it clicks. Dual-side opening with SlideLock makes loading and locking easy from either side.
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.
