The Oakley Kitchen Sink Backpack offers every conceivable innovation, from a mobile phone pocket to a padded sleeve that holds a laptop up to 17". The top storage compartment is compression molded to protect eyewear ? or use it for a media player and take advantage of the headphone port. Cable zipper pulls let you add a lock to secure the main compartment. The mid-body access flap includes an inner organizer, and a compartment at the bottom has drainage ports for wet or soiled items. You also get plenty of pockets, attachment points and tie downs.
