Scream 25

At first glance, the Mountainsmith Scream 25 backpack looked a bit smaller than I first imagined—but after filling it with my books, an extra scarf, and coat, I realized that it was reminiscent of the carpetbag Mary Poppins carried around. Due to my love of Mary Poppins (as well as my constant search for a magical bag like hers), I was thrilled that the Scream 25 could fit all of the random stuff that I carried around with me. While it works great around campus or on light day-hikes, the small waist straps aren’t built to support overzealously heavy loads—thankfully, the thick shoulder straps help make up the difference. $70;
