Why this product
Why the Thule Force XT XL?
The Force XT XL delivers 18 cu ft at just 37 lbs — that's significantly lighter than the Motion 3 XL at the same capacity. Central locking and 165 lb capacity cover the essentials. Here's the thing: if weight matters more than dual-side opening, this is a smarter buy. The downside? Single-side opening only, and the Force XT line lacks the Motion's premium fit and finish.
