In terms of security, the skyboxes in Yakima are among the best. The Super Latch Safety bars along either side of both of these types ensure that the lid is always closed fully.

These boxes are even more secure thanks to the three-lock system, which makes them very impossible to break into. As a result, you shouldn’t have to worry about your belongings being stolen when traveling or while camping.
