Backpacking through Europe to "find yourself" or heading to your first weekender at your big brother's fraternity house (where, let's face it, you could probably end up "finding yourself"), there's a pretty big chance The North Face has the perfect bag for your souvenirs, whether it's a shamrock from Ireland or a bra from one of the Delta Gamma girls.
If you're planning on a serious, multi-day excursion, The North Face Base Camp Duffel wouldn't be a bad way to go. Another good choice would be the Rolling Thunder Wheeled Duffel, which lets you roll it or carry it and is great on space while meeting those wonderful airline requirements.
Perfect for work, campus, or site seeing, you can't go wrong with a shoulder bag from The North Face. The Calyx Classic Shoulder Bag gives you space and organization with magnetic front closure, front and back zippered and Velcro pockets, as well as a cell phone pocket.
