Packs your Mac and your board.
The Trap Door skate carry on the DAKINE Covert Pack isn't exactly like those trap doors people always happen to lean against and then fall through in the movies. But it is a wide strap on the back of the pack that turns this laptop-compatible daypack into a skateboard carrier. When you get to class, pull your 13 x 10inch laptop out of the Covert Pack and stash your shades in the padded sunglass pocket. An organizer pocket keeps pens, keys, and your cell handy.
