Whether you need a pack for class or for a party afterward, grab yourself the DAKINE Prom Pack.
Slip your laptop into the DAKINE Women's Prom Pack and head to class. Afterward, grab a couple cold drinks from the insulated cooler pocket and kick back with friends. The DAKINE Prom Pack includes 1750cu inches of cargo space to get you through a long day of hitting the books, and the front organizer pocket keeps your pens, phone, and iPod quickly accessible. This fully featured pack even has a fleece-lined sunglasses pocket to keep your shades at the ready.
I haven´t actually used it yet, but I´m sure I will. It has lots of compartments which I look for in a bag, it even has one that keeps your drinks cold! :) It is also a really cute backpack with the pattern on it.
