Actually this isn't nessesarily true. If your internal frame pack fits
well enough you can put as much weight on the hips as with an external
frame pack and take as much weight off the shoulders. Plus since it
rides closer to the back and weight can be loaded lower than with an
external its a much better choice for cross country trippin'
