Timbuk2 Vault Backpack 1953cu in

The last time you commuted to class with a backpack that had mesh pockets and other dangling bits, a car ended up clipping a loose strap, and you never saw it again. The Timbuk2 Vault Backpack comes in a strapless, streamlined style so you don't have to tell your professor another bizarre story about how you lost your homework. Timbuk2 even added a side slip pocket for your U lock with you're riding.
