The trip to campus is an adventure all on its own, so we travel with the Recon 30L Backpack in tow. This one massive pack has enough space to get us from 7:30 economics to our dreaded night class without taking a trip back to the car. Not only is the main compartment large enough for textbooks, snacks, a sweatshirt, and all our chargers, but there's also a separate stash made just for keeping our computer safe and sound. Still doesn't sound like enough space? Pockets and daisy chains cover the outside of the pack, so nothing gets left behind.
