Yakima RocketBox Pro 11

The RocketBox Pro 11 is Yakima's smallest hard box at 11 cu ft and 35 lbs. It fits compact cars and small crossovers where larger boxes won't work. The downside? At 35 lbs for 11 cu ft, you're getting less volume per pound than almost any competitor, and the entry-level construction means basic mounting hardware and less refined seals.
