Trade the pocket-filled backpack of your high school days for Timbuk2's Hidden Messenger bag, made from 90 percent recycled PET bottles. Though it doesn't have the same organizational qualities of other Timbuk2 messengers, it's designed to fold up into itself so you can toss it easily in your bag for trips to the grocery store, carrying home extra books from the library, or using as a carry-on for trips home. Plus, it's also not as bulky as other bags, so you can carry books and papers for one class at a time without hauling a giant bag. (Timbuk2, $30)
