From Thinkgeek:

This Marvel x MadPax Spiderman Backpack holds everything required for your secret identity, like your Daily Bugle badge, your camera, and your tablet for taking notes. You can throw whatever you need in here, which is useful because there aren’t pockets in Spidey’s costume (unless it’s Rob Liefeld’s Spidey, but we’re going to just pretend like that didn’t happen). Hey, look! A backpack!
