External Aluminum Frame Backpacks

Every backpacker needs a good backpack.  They need a sturdy and durable backpack to carry their gear.  In addition, the choice of a backpack is essential to a good backpacking experience because differences in design can affect the weight and ease of carrying a backpack.  The backpack you choose should be comfortable and able to hold all your essential gear.  There are two basic types of backpack construction- external frame and internal frame. 

External aluminum frame backpacks are backpacks that have the frame on the outside.  The actual pack bag is hung on the frame.  They are usually rather large and extend above the head when worn.  They usually have a lot of pockets and allow for space between the back and the pack for excellent ventilation.   An external aluminum frame backpack is suited to carrying heavy loads, but should be used on-trail only.  They have a high center of balance so they make falls very easy if a person is on uneven ground or tries to bend down.    

Internal Aluminum Frame Backpacks

Internal aluminum frame backpacks have the frame on the inside.  They fit snug against a persons back which makes them easier to carry than an external aluminum backpack.  A person will have a natural sense of balance with an internal frame aluminum backpack so they are good for both on or off trail.  The smaller size means they carry less, though.  They also do not have as many pockets as an external aluminum frame backpack.

When making the choice between an external aluminum frame backpack and internal frame aluminum backpack you really should focus on a few factors.  First you need to determine the average load you carry.  Consider if you need a lot of pockets or compartments.  Next you should think about your typical backpacking trip and what type of terrain you usually travel on.  These things will help you determine which type of backpack is best for you.

Internal aluminum frame backpacks and external aluminum frame backpacks each have their own good and bad points.  The choice will really depend on the type of hiking a person is going to be doing.  External aluminum frame backpacks are good for heavy loads and trips on trails and smooth terrain.  Internal aluminum frame backpacks are good for smaller loads and for more diverse and rough terrain.
