 here are
two main types of backpacks: internal frame and external
frame.
Both frame types are designed to place approximately
eighty percent of the weight on your hip and twenty percent
on your shoulders. In doing this, it allows you to maintain
proper posture while hiking.
Internal Frame Pack |
Internal Frame:
These packs perform well when heavily loaded. Because
they conform to your body as you walk,
they are very comfortable. They also have compression
straps on the sides so that you can compress the
pack to fit better. Although they are more comfortable,
internal framed packs are limited to the size of
the bag so that you can not strap many things on
the outside. They also tend to carry the weight
lower on the back which may cause you to bend over
more as you hike.

External Frame:
Packs with external frames are better for strapping
on extra gear. for more items on a smaller pack.
They also have a space between you and the pack
for airflow. However these packs have little flexibility
which can make them unstable while walking.
