With its long and narrow design, the Yakima RocketBox Pro 11 Cargo Box won't monopolize every last inch of space on your cross bars. At 226cm, this box is plenty big for your longest skis or board, and it'll still have plenty of room for all those on-mountain extras you need throughout the day. Included SKS locks mean your gear stays safe when you're transitioning to apres activities or pulling off the interstate for a bite to eat. Dual-sided opening and a simple push-button mechanism promote easy access to everything inside. The RocketBox Pro 11 mounts to Yakima's round, square, and aero bars, also fitting a wide variety of factory and aftermarket crossbar systems.
