You're backpacking around Europe. The center of your existence is going to be your backpack. Choose wisely.

You want a backpack that not only goes over the shoulders but secures snugly at the waist.

Types of backpacks:

• External frame -- good for trekking, but bulky and heavy for city travel.
• Internal frame -- keeps everything self-contained, but limited options for external attachments.
• Wheeled -- preferable, but sometimes not as back friendly.

Ultimately, buy the biggest, lightest pack you can manage. Do not start out with it completely full.
