Why this product
Why the Thule Force 3 L?
The Force 3 L gives you 16 cu ft and 165 lb capacity with Thule's Quick-Grip mounting and central locking — it's the practical choice when you don't need the Motion 3's premium finish. At 43 lbs, it's nearly identical in specs to the Motion. The downside? Single-side opening only, and the materials feel a step below the Motion line.
