The backpack is a key component of any hiker or camper gear. Choosing the wrong backpack can lead to pain, exhaustion and even potential damage. The performance of the internal frame backpack and the external frame backpack is different, so choose the style that best suits your personal fitness and the way you plan to use the backpack. The interior frame backpack is fairly flexible and is designed to keep the load close to the body. They have many support points on their shoulders and waist and a comfortable fit on their back. The outer frame backpack is sturdy and durable. The rigid frame is easy to support heavy objects, but depends on fewer support points on the body. The outer frame backpack is slightly away from the body, while the inner frame backpack embraces the back. If you are prone to overheating, or hiking in very hot weather, you may prefer the airflow associated with the outer frame pack. Adjusting the installation of the internal frame components can overcome this difference to a certain extent. The inner frame backpack tends to push the center of gravity slightly forward, while the outer backpack pulls the body slightly back. The slight nudge of the internal packaging makes it easier to maintain balance on uneven terrain, but the pull of the external packaging allows you to walk upright more naturally. The outer frame package is larger in size and wider in shape than the inner frame backpack. The shoulder strap is usually narrower on the inner frame package, making the arms completely free. If you plan to take part in activities such as skiing, rock climbing or hiking by rebrushing, the in-house frame backpack provides better operability. Compared to the external frame pack, the internal frame backpack has fewer individual pockets and compartments. This can make them more difficult to pack. Items needed to arrive quickly can also be more difficult. There are a wide variety of storage points on the outside of most external frame backpacks that allow you to quickly pack, open the package and get to what you need. The external frame provides a location for attaching additional items that are not suitable for packaging. Lisa Fritscher is a freelance writer specializing in adventure travel for the disabled.
