Why this product
Why the Thule Motion 3 XXL?
The standard Motion 3 XXL delivers 21 cu ft at 55 lbs with dual-side opening and automatic lid lock. It's the largest in the Motion 3 lineup without the Low profile compromise. The downside? At 165 lb max capacity, you'll run out of weight allowance before volume on heavy gear, and storing this box when not in use requires serious garage space.
