Um, why is there salt water dripping out of the drain ports on your Oakley Surf Pack 5.0 Backpack? Wait a minute, you breezed into class and whipped your laptop out of a padded, side-access pocket in that backpack, but that pack is still plenty stuffed. And you were a few minutes late. So you have your music player, shades, and cell stored in those front and side pockets. But were going to go ahead and guess you have a recently-worn wetsuit in a water-resistant compartment somewhere in that Surf Pack.
