1. Internal Frame
The majority of backpacks today are internal-frame packs, meaning the support rods and frame are built into the backpack and hidden from view. However, there some are still external-frame backpacks, where the rods are separate from the actual pack and stick out (think of those backpacks you see in old

It not only looks better but the rods won't get caught on anything and your bag will also be slimmer, making moving around easier. Additionally, internal-frame packs tend to be lighter as the frame is composed of carbon fiber or tough plastic, which makes them easier on your back as well as more durable.
