Internal or External Frame?

The Difference Is Personal

Choosing between an internal frame and external frame backpack is really just a matter of personal preference. However, there are differences in how each is packed and their individual capabilities for storage and comfort.

Internal Frame

Internal frame backpacks can be identified by their, usually, flexible, padded frame that is held in the fabric of the pack. One advantage of this type of pack is that it holds the weight closer to the body, moving the center of gravity closer. This is good for uneven terrain and cooler weather.

Backpacks with internal frames usually do not have as many storage options as those with external frames. The pockets are also, usually smaller. This can make packing and quick retrieval of items difficult.

External Frame

External frames can be identified by their obvious metal or plastic external skeleton which the backpack itself attaches to. The advantage to this pack comes in warm weather, where airflow between the pack and the adventurer keep them cool. However, it pushes the center of gravity backwards, changing how the weight is carried.

External frames usually have bigger compartments and attachment places for more storage and gear. This makes them much better for longer stays in the wilderness as well as for packing for multiple people, such as for children who can not carry as much weight.
