The biggest roofbox here, this could have swallowed our gear twice over – and it’s long enough for skis, too. The styling is not to all tastes, yet the box is well made and sturdy. We like the wider-than-average lid opening, but would prefer dual side hinges. Given the enviable construction, the relatively short three-year warranty is surprising.
