At first glance, Cocoon's nylon and water-resistant sling bag looks like a giant iPad fanny pack. Its awkward shape makes for a horrible over-the-shoulder messenger bag, but it's actually meant to be carried behind the back like a one-shoulder backpack. In that position, however, it feels ripe for someone to rob your iPad from behind. This bag does have a nice side pocket and an additional MP3 player pocket, plus the debatably useful Grid-It card, which has overlapping elastic bands for holding various gadgets in place. Honestly, we would have preferred slipping our gear into pockets instead.
