Why this product
Why the Thule Force 3 M?
At 13 cu ft and 37 lbs, the Force 3 M is a solid entry-level Thule box — Quick-Grip mounting, central lock, 165 lb capacity. Here's the thing: for weekend trips and ski season, 13 cu ft handles two people's gear comfortably without the bulk of a larger box. The downside? Single-side opening, and the ABS construction feels less premium than the Motion line.
