Thule Motion 3 L Cargo Box – 16 cu ft of Aerodynamic, All-Season Roof Storage

The Thule Motion 3 L adds serious, weather-protected capacity without bulky looks or excess wind noise. With dual-side opening, secure SlideLock, and the fast, tool-free PowerClick mount, it’s a premium roof box for year-round travel across Canada—ski trips, camping weekends, and long family road adventures.

Thule Motion 3 L – Frequently Asked Questions

How much gear fits in the Motion 3 L?
About 16 cu ft (≈ 450 L) — typically 5–7 pairs of skis (up to ~180 cm) or 3–5 snowboards, plus duffels and boots.
Is it easy to install and remove?

Will the rear hatch clear?
On many vehicles, yes. The Motion 3’s forward position improves hatch clearance—always check your rack/vehicle combo.

Up to 165 lb, but never exceed the load limits of your vehicle or roof rack system (use the lowest rating).
What crossbars will it fit?
Works with most aero, square, round and factory crossbars within Thule’s recommended bar-spread. Verify fit before purchase.

Excellent experience!! We called the store and they answered right away, which was awesome. Ordered a Thule bike rack. The gal on phone said she would ordered it and it came the next day which was a pleasant surprise. Staff was professional and friendly! They will be getting all of our business going forward!
