The Thule Motion 3 XL is the perfect all-rounder—offering 18 cu ft (500 L) of cargo space while maintaining a sleek, aerodynamic profile. Ideal for family trips, sports gear, and daily hauling without adding bulk or noise. Fits 5–7 pairs of skis (up to 200 cm), 3–5 snowboards, duffels, and camping gear—while clearing most SUV rear hatches and pairing seamlessly with major crossbar systems. Mounts fast with Thule’s PowerClick system—just 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.
