Why We Like The Thule Motion XT Cargo Box

The Thule Motion XT Cargo Box optimizes gear storage atop our adventure mobiles. It's available in three sizes to suit our personal needs, with each size able to hold up to seven pairs of skis or five snowboards. Its spacious interior holds all our gear without drastically reducing fuel economy, thanks to its sleek aerodynamic shape. It easily and securely mounts to nearly all Thule crossbars with its PowerClick dial, which provides an audible click when it's fully secured in place.
